Interpolated distance may be about correct just by accident, not because of more accurate raw data. Edge 520 plus and my iPhone for a test hike. We also found that most GPS devices overreport distances, though usually by less than 3%. The Best Choice Is… For nearly every purpose, people will find an iPhone or Android performs better than a Garmin or other outdoor GPS unit. Two and a half years ago we conducted a test to see which was more accurate for recording distance and elevation data: a standalone GPS unit or a smartphone running a GPS app like Strava. How GPS in your Smartphone works. Garmin Oregon 450t Handheld GPS Navigator. what’s my longest one day ride of the year? Errata: In my previous post, where it says “number of revolutions” should have said “number of wheel revolutions”. Your iPhone … It seems that the new Sony GNSS chips used by Garmin from 2019 onwards can only use the E1 frequency (Galileo) and the L1 frequency (GPS). Mountain Bike Deals, Copyright 2020 Blue Spruce Ventures LLC | Ah, indeed. He writes code and manages the business. SALES AND PROMOTIONS . Might also be a pain if you are wearing gloves. But I would say that GPS technology is changing so fast, and improving, that buying a fixed cycling device as opposed to using your smartphone is leaning towards the smartphone, in my opinion, because they incorporate new GPS tech each release and you replace your smartphone more often. I’d like to get a Garmin, but I can’t help but think that the phone apps will catch up pretty quickly to the accuracy and quality of these watches? All the devices we tested were within 3% of our one-mile benchmark, and all but the iPhone apps were completely consistent from test to test. Like most cyclocomputers on the market, the Cateye Velo 7 measures the frequency and number of revolutions the bike wheel makes to determine speed and distance. Proponents of Garmin and other standalone devices may cite the battery life, accuracy, and ruggedness as reasons to prefer these units. Garmin vs IPhone: Accuracy. Ridiculously good deal. It is every bit as accurate (and fast) as a dedicated GPS device (which I used to use extensively). The latter sounds more plausible, but the other two explanations could also be at play here as well. Please check a document to certify athletic road races (USATF). But found instead that both sites had ALL my rides. It will show how to calibrate the bike (pages 9-17). Thinking I had somehow left out some small ride in Strava, I searched in vain for the discrepancy. Support . The Garmin Edge 520 does deserve props, however, because it was more consistent than the iPhones. We've had a lot of data discrepancies between the two. Where it says “point to point mean square error” would be better understood if it says “point by point mean squared error” so the error of each GPS point is averaged, and not the error in distance between two inaccurate GPS locations. At least for the calibration. What do you use for wilderness exploration? Another thing I have noticed is the difference in online services. A: Great question because everyone gets this one wrong. The cost, ease of use and battery life are probably more important. It’s even worse doing a hike or run to the point of being unusable. Blog Careers. Well, after this second round of testing, we can confirm the track is indeed a quarter-mile track, as more than one device measured 4 laps at exactly 1 mile. And even limiting it to that, it’s flawed. The map … When I had my iPhone 6 I noticed on my best time on some sprint KOM was 16s and to this day my overall (everything) has improved yet my best time is 18s and I cannot beat it no matter what, even if I physically feel much faster. I conducted an initial “calibration run” with an iPhone and both watches for 30 minutes, in an open area with a good GPS signal. Garmin eTrex vs iPhone for GPS accuracy 22 June 2019 / 0 Comments / in GIS, Google My Maps, GPS, News / by Anthony Bennett. So, to get exactly 1 mile from our test, we should have set the wheel circumference to 228cm, which seems like a big difference from 233cm–more than the amount I would expect the tire to deflect. I use MotionX GPS extensively and the accuracy is always much worse than every other iPhone in my family (iPhone SE, iPhone 6, iPhone 5). The test took place at around 4pm local time with partly to mostly cloudy skies. (Again, this is a shame because the on-device summary for the single test we were able to complete with the Trywin shows zero elevation gain or loss, which is pretty much spot-on correct.). What’s your opinion on using an iPhone app like Runmeter vs the dedicated GPS watch? So, it’s possible our actual riding tire circumference was less than 233cm. For this measure, we would expect elevation variation (that is, the difference between the minimum and maximum elevations) during the tests to be essentially zero since the track is flat, though to account for a slight variation in elevation around the track, we’ll say that 1 foot of elevation variation is just as accurate. Best MTB Gear | 6. Widgets, Explore Rather than being an all-purpose communication … There are more factors, like battery life, roughness, easy of use, configuration options, screen readability etc… The result: the Cateye Velo 7 reported our 1-mile test circuit was 1.02 miles long, or 2% longer than the actual length. 5. I know is a 3 year old article but it still appears in the first page in google. I have detailed 1:50000 Topo maps for the whole of NZ (and Australia) pre-loaded on my phone. But measuring the delta of short distances like a thousand readings around a short 1 mile track can have a lot of compounded error. To be fair, your watch does have some great features that a phone simply can’t replicate. This next generation GPS … phone's GPS probably not accurate enough? How to Use the Singletracks App to Find and Ride... Singletracks App Updates + Singletracks Trail Challenge Launch, Hitcase Pro and ChestR: Your iPhone is an Action Camera, Strava Creating BOM Award to Recognize Pricey Bikes. It’s impossible to conclude that the smartphone is more accurate when it has cancelling errors (one must use point to point mean square error to really assess the accuracy) We believe Gaia GPS is the best app to use your smartphone as an outdoor GPS, but there are dozens of other apps you will likely find preferable to a Garmin, as well. I quickly learned that the iPhone’s battery capacity is so poor that I cannot use it as the exclusive GPS for hikes over about 4 hours. There was some question last time as to whether our track was a metric, 400m track or a quarter-mile track. 2. Discussion. I totally agree that we shouldn’t expect any of the GPS devices to be perfect. Of course this could be due to the mix of devices we used in the two tests or even the weather, but it does seem plausible that GPS hardware and software are continuing to improve. The Accuracy of GPS and GLONASS. We used the same running track as in our 2014 test to ensure a course of known distance in a controlled environment. The Lezyne Mini GPS had a real problem here, showing wild elevation variations of up to 53 feet in a single test. Best Bike Trails | Your mileage may vary. Since the only comparison that matters to me is among my numbers (i.e. Fenix … I put all my rides into both Garmin Connect and Strava. Apple Watch Vs Garmin Forerunner 220. I think you were missing the other mike’s point about the test. Your distance isn’t representative to what people are trying to do. The included documentation suggests a circumference value based on wheel diameter and tire size, which in the case of our test bike, was 233cm. If you’re just using GPS for navigation, I totally agree that any unit you chose will be more than accurate for that purpose. Every lap as you turn around the track you are making many measurements of location but each one can be off by 30 meters and the quality of your satellite lock is changing as you turn. I was actually pretty shocked to see how well each device did in our test. In this post, I wanted to publish my results on a little testing of the accuracy of the GPS on my iPhone 5, specifically in a location with no cellular service, no data, and no WiFi. So at least for me, the F5x has trouble keeping track. So can the device get the data from the satellites. While some of the phones with Snapdragon 855 here have their dual-frequency GNSS abilities enabled - the OnePlus 7 Pro and Oppo Reno 10x - they don't necessarily show better accuracy than, say, the Pixel 3 with Snapdragon 845, or the LG G8 with Snapdragon 855 itself. GLO 2 can receive position information from both the GPS and GLONASS satellite constellations, allowing it to connect to up to 24 more satellites than devices that rely on GPS alone. Singletracks may receive compensation for purchases made through affiliate links in this article. The good news is your phone doesn’t need a cell signal to find your location. Support Us | Fair enough. 43. Hence the value of multiple constellations. Everyone hates seeing the ‘battery life: 10%’ sign flash up on your screen, half way through a 50-mile ride.The Wahoo Elemnt has a stated life up to 17 hours, whilst the Garmin Edge 520 lists a 15 hour span. For the devices we tested this time around, the Strava and Endomondo apps on iPhone reported the closest average elevation to actual (1014.4 and 1013.5, respectively) while the Bryton Rider 330 reported the least accurate elevation, averaging 733.7 feet across the three rounds of testing. Given the rapid advances in phone technology, we decided to test if your iPhone could really give you the same accuracy as a GPS watch on the trails. So trying to measure a distance of 1609 meters, to less than 1% error, with a tool that at worst can be off greater than 1.5% or 30 meters for each measurement is not valid. ** This does depend heavily on the layout of the course, which we will detail in a future article. Your bike computers like Cateye will be far more accurate, while the altitude will be more accurate on a GPS. Right now, there's a CNET exclusive on the 4.3-inch Garmin Nuvi 1390T, which costs a mere $89.99 and includes lifetime traffic data. Most of the time we want to know if we are on “the route” or way off and if we passed the “half-way point”, how far is it to the cut-off etc. That second part blows my mind. But any device can be in the shadow of satellites due to ground based objects and therefore it doesn’t have a good reading for that last measurement or a satellite it was using sets and it needs to acquire a new bird coming over the horizon. Cancel; Up 0 Down; Reply; Verify Answer Cancel; 0 sis651 over 1 year ago. It has GPS, it has a heart rate sensor, it even has an altimeter and shares an app with the Garmin Forerunner 935. If you’re point is to show out what each device does to Strava KOM’s then actually go test all the devices on your bike at the same time and do 10 different KOM’s in your area and see which ones if any give you better results vs the official elevation and distance Strava has for the KOM.

Thank you for your considered reply, and I … Thomas. $135.15 at Amazon. GPS is only accurate at best to a few meters and at worst to 30 meters. The Trywin GPS listed in the results is an inexpensive GPS we picked up online and reviewed several months ago. Yet, the summation for the year’s total was not the same. The Endomondo app had problems as well, showing an average of 12 feet of variation per test. Some Garmin watches can be configured to either record every second, or only record when something happens, such a change in heart rate or change in direction, something they call "smart recording." Also, it should be noted that the Strava app itself only reports distances to the nearest 0.1 miles, so we had to run the iPhone 6s data through an online tool to get more precision, meaning that result is not 100% verified. A dedicated community for Garmin users to ask questions, provide answers, and share feedback. In fact, the reason we decided to do this test was because people were arguing about whose device was more accurate, and who was “cheating” by using an inferior device. So, if you want to repeat the test in the future, you need to have a set of tests. Andrew founded Gaia GPS. This is a followup post to How to Find Your GPS Coordinates on an iPhone. GPS vs Smartphone APP. 3. That does not mean it is not useful. The more satellites and the better quality signal the better the accuracy. Compared to our first test, it seems GPS devices and apps are becoming even more accurate than they were even just a couple years ago. I placed my GPS on a few caches (everyone does when they get a new unit ) and it was in the 2-4 ft range. You are playing within the error bars of the device. Both the Edge 520+ and my iPhone worked just fine, but F5x lost tracking 3 times (for a long period of time) during a one hour test hike. Unfortunately the button combos and menus are so complicated I failed to correctly start and/or stop the device during our first two tests. Even by pure luck, you can save couple of seconds at the start and at the end as the algorithm chooses the closest points to start and end, specially in short segments. Sometimes up to 2mph difference and 1mi or more difference on a 10mi ride. Close. After reading through all the comments on our previous test, we knew we needed to perform a follow-up test, and since it’s been more than two years since the first test, we would need to bring in a new crop of GPS devices. Garmin Autoland. About Us | iPhone X GPS accuracy is the same as iPhone 8, 7, 6S, 6, 5S and all recent galaxy phones. Discussion. One that measures optimal conditions: Long straight line without big trees or buildings on a clear day (this will be very close but can help detecting weaknesses in GPS antenna or algortihms, as well as helping to calibrate speed sensors), then you can vary the scenarios: Twisty road, elevation changes, under canopy, near buildings or big rocks, wet conditions, etc… (don’t forget repeatability of tests). My question is I am debating between a SD card for my Garmin or using my old iPhone 5s as a dedicated GPS by saving the maps for my areas. The Garmin Drive 52 & Traffic is one of the … Without wasting any time, let’s review some of the most accurate GPS devices available on the market today. The least accurate device in our test was the Bryton Rider 330, which consistently underreported our control distance by 3%. ), I have my answers without any loss. The short version is this: your GPS signal is separate from all of these, so you can still get an accurate location from your iPhone’s Compass app. Send us a note at firstname.lastname@example.org, and we’ll post your story. This allows GLO 2 to lock on to satellites approximately 20% faster and remain connected even at high speed. * The Lezyne Mini GPS we tested is an older model, and is not the same device that is currently on the market. I don’t have to use data to download maps for … Your 2nd best option is the number of revolutions, but the way you measured it it not right. The Garmin Edge 520 comes in close behind, adding just another foot or so to the variation. It depends. The most common objection to using a smartphone for backcountry navigation is, “Where I hunt there’s no cell signal”. The short version is, while smartphones might not have GLONASS support (the Edge 520 in this test does include it), they’re often able to use additional sensors like Wi-Fi and cell tower triangulation to improve accuracy over a single constellation system. According to my calculations, the cyclocomputer clocked 706 revolutions during the test. It even looks to me, that iPhone might not always match a previously created Strava segment on “random” route, if there’s so much variation as it looks like. Just … gps or phone.

Your tests really don’t have much value. Yet, in MTB, it’s completely unrealistic to rely on GPS (trees, rocks, bridges, buildings, electric lines) or speed sensor with the wheels jumping from rock to rock or sliding while breaking into a corner. 4. Measuring elevation is notoriously tricky for any device, whether the device is using GPS signals, a barometric altimeter, or both. Posted by 1 year ago. The chart above shows the elevation profiles generated by each app and device. 6. Due to this reason, the best accurate GPS devices have used supporting programs such as the DGPS (Differential GPS), WAAS and GLONASS to boost accuracy. MTB Podcast | However, these needs can all be addressed, while still offering the benefits and low price of a smartphone: For my money, a smartphone with Gaia GPS is the best outdoor GPS for backpacking and backcountry skiing. Proponents of smartphones point out that they offer better maps, larger screens, better software, for a fraction of the cost of a standalone GPS unit. tagnut69 . Strava segments are just a ridiculous competition: One may use an e-bike, other has a far lighter bike or better tyres, the next got lucky with a strong tailwind… or someone crafted a GPX file… Well, after this second round of testing, we can confirm the track is indeed a quarter-mile track, as more than one device measured 4 laps at exactly 1 mile. Can a Smartphone Replace a Dedicated GPS? Using other GPS apps and MotionX together I discovered multiple problems. GPS accuracy VS Garmin. The differences lie in the antennas, receiver resistance to noise and how many satellites it can triangulate with. The wheel-based cyclocomputer we used for this tes… I also know a few riders … While absolute accuracy might not be all that valuable, hopefully these test results at least hint at relative accuracy among devices and device classes. Close. Q: What is the accuracy of the iPhone GPS? Elevation data collection, on the other hand, is much more variable, and the use of online services like Garmin Connect and Strava can have a big influence on the accuracy of that data. Can you save points and things on the phone like waypoints on a GPS? As one reader mentioned, the traces for the GPS units are FAR more consistent than both iphone traces. I will now run home from work … That is because none of the smartphones come with a GPS chip in them. How accurate is GPS? On this measure, the Strava App on iPhone 6s is the most accurate, averaging just 1.2 feet between the minimum and maximum elevations reported. 6 comments on “ iPhone GPS vs Garmin eTrex ” Jeff M on September 14, 2011 at 10:43 AM said: When I upgraded to an iPhone I thought that my days of carrying a Garmin 60CSx were over.

This is because the sat nav devices of TomTom are exclusive for those that you can use in car travel. However, if we are talking about the product line, Garmin wins as the more diverse. IMBA Epics | Below, we’ll discuss why an iPhone or Android is better than a Garmin, and also talk about what Garmin and its proponents will tell you. While knowing the actual elevation above sea level during a ride is interesting, most mountain bikers are more interested in knowing how much elevation change was experienced during the ride. Not knowing the “true” value, I have simply decided to accept the value direct from the head unit as “the” distance. Posted by 3 years ago. Singletracks Merch | Member. This time around, we added a wheel-based cyclocomputer for comparison, and performed multiple rounds of testing to get a sense of both accuracy and consistency among the devices. Of course we need to do more testing, but this suggests that two riders, with the exact same device riding the same course at the same time, should get nearly identical results. But an iPhone has access to better maps, better software, at a price that can’t be beat if you already have the phone. Last year’s total mileage reported between the two sites differed by 6 miles (out of a total of 3200). Garmin’s tracks are by far much more consistant between each test, with least variation. The iPhone 5 looks to be around $500-600, the Samsung Galaxy S4 around $400-500, and the Google Nexus 5, though a great value, is still $349-399. I find the GPS units far more flexible, so you can have more constellations, WAIS, enable 1s recording. Officially, the iPhone 6s running Strava and the iPhone 6s Plus running Endomondo were the most accurate in our test (±0.67%), followed closely by the Garmin Edge 520 (+1%). In that test we found that GPS apps, running on a smartphone or even a tablet device, can record very accurate data. Shop now. 2. This time around we ran three, one-mile tests instead of a single, 10 lap, 2.5-mile test. Any thoughts? Garmin Drive 52 & Traffic. In fact, official running events require the use of a similar, wheel-based device for certifying course distances, because this method is generally known to be quite accurate. This is as against Garmin, which has GPS devices that can be used when biking or hiking, among others. There was some question last time as to whether our track was a metric, 400m track or a quarter-mile track. Both Garmins and iPhones are suitable for getting GPS information, offline, without cell service. Archived. The bottom line point is that you probably could run the tests over and over exactly the same and come up with different results each time. In fact, the Strava app on an iPhone and an Asus tablet reported more accurate data than any of the standalone GPS devices we tested. We used the same running track as in our 2014 test to ensure a course of known distance in a controlled environment. This was to calibrate and set-up the Apple Watch (as per the instruction manual – see the results below). GPS or smartphone for geocaching? Archived. The two most popular watches are the Garmin Forerunner and Apple Watch. Each test took place with a short rest in between to stop and restart all the devices. I believe it has to do with the delay (8sec, 10sec, 30sec ?) Either Strava rounds off the numbers before summing a little differently than Garmin Connect, or there is a loss in precision in the transfer from Garmin to Strava (I use the automatic link), or the Garmin summary is taken from the activity summary data supplied by the unit (which would be summed before any conversion and storage) whereas the Strava distances are computed from the track points then summed (extra steps so extra opportunity for round off error). Terms | Privacy, First published January 25, 2017 @ 4:27:29. And while the Trywin GPS does measure elevation data, we don’t have a way to get the raw data off the device to analyze it, making it impossible to compare to the other devices. 1. Riding up and down hills will show less than actual mileage on a GPS. Quote ; Share this post. My running club has a mix of fitness watch users. What’s more, GLO 2 updates its position information at 10 times per second; that’s … (The Cateye Velo only accepts whole numbers, so we used 233cm.)

Hiker, hunters, offroaders, skiers, and even professional firefighters, rangers, and researchers have adopted smart phones for outdoor recreation and work. However, averaging all the device readings across all the rounds of testing shows an overall average reading of 1.003 miles, which makes a strong case for saying the true length of the test route is indeed 1.0 miles. I was keen to find out how the iPhone and the dedicated GPS device compared. Where it says “WAIS” should be “WAAS” The Apple Watch is on my left. Your gold standard should have been the track, but you don’t know if it’s 400m or 1/4 mile. Hi all, I'm curious to how accurate Strava is on my iPhone SE. I wish I could dig up the conversation but someone literally suggested that Strava should flag KOMs that were earned using a smartphone vs. “more accurate devices” like Garmin GPS units. DISCOVER . Using data and research from our previous test on this track, the correct elevation for the track should be between 1,014 and 1,015 feet above sea level. Good points Mike. It is frequently connected to 7 instead of 8 that older iPhones show in the same area. So, my hope is these results convince virtual racers they should stop stressing over virtual race results, since there is no way to definitively say ANYONE’S results are 100% accurate. The garmin users are mostly the same using … Smartphone apps still dominate in terms of accuracy, and inexpensive GPS units appear to report the least accurate data. This article looks at the pros and cons of using a dedicated GPS vs a Smartphone for backcountry navigation to help you select the best device for your next hunt. Cool idea, but I’d have liked to see some better test cases essentially. It’s a shame, too, because in the third test when the GPS actually worked, the Trywin turned out to be the most accurate, off by just 0.3%. GPS sampling rate allows a watch to turn off the GPS receiver for short periods to conserve battery life while sacrificing GPS accuracy. I suggest you read that for a little context. The Oregon 450t is our first pick for a handheld GPS device. More important to the buyer is what satellite constellation the device uses. With a smart recording in normal GPS mode, the GPS system is … We all leave our phones in the car. It should be noted that neither the Strava or Garmin data was taken directly from the device, allowing those respective online services to potentially correct the data in the cloud. The Strava KOM is based off mapping data for its distance and elevation change so that seems like a decent, demonstrable control case for the different results. Even the stalwart of cycling distance measurement, the cyclocomputer, clearly has its flaws and can’t be considered much more or less accurate than GPS and smartphone devices**. Reply. Support Center Aviation Support. For nearly every purpose, people will find an iPhone or Android performs better than a Garmin or other outdoor GPS unit. You could buy a Garmin Edge and a Garmin Nuvi for less than the Google Nexus 5! Enter your email address to receive our top stories via email each week.
