Now I understand what that funny reverse connector I found in the box was for - to connect the USB cable from the Garmin to the phone.Īll I have to do is set up the Garmin to send out NMEA sentences, turn off the phone GPS, turn on developer mode and allow GPS mocking to read the external stream instead. So the ideal would be to connect the Garmin to the phone and adjust on the fly. I agree that external post-processing is a hassle, the phone uses local timestamps but the Garmin uses UTC times and we have daylight saving too. I have done a comparision with tracks from the Garmin and Galaxy and there is a significant error (+/-15 metres) using the phone. ![]() My Tracks records and displays your distance. Averaging for waypoints where you stay still for a while improves the accuracy for some purposes. If you have a GPS-enabled Android phone, you can get most of the same features for free with Googles My Tracks. The coordinates returned by my phone are still not very good because the photos are too fast for averaging to take place, if that was enabled. That is a pity because my Garmin 78C does and there is an experimental service in my area. This thread started in 2016! But it reports it does not use SBAS signals. So new phones can see all the new satellites now (2018+). In the GPS Test app I can see all the satellites from US, Russia, China, Japan, EU. Therefore they show different values for the same track.My Galaxy Note 8 seems to receive all constellations. Other apps use different algorithms to calculate the ascending and descending altitude values. M圜arTracks can be set to capture position every 2 seconds for 100 accurate and no-mile loss records. ![]() If you ride a route where you always go up and down less than 10 meters, the ascent and descent altitude values will remain at zero. As it records, you can see the data live, introduce notes regarding your route, and even listen to comments on your progress. The difference between two altitude values must be greater than 10 meters for myTracks to add the difference to either the ascending or descending altitude value. My Tracks is an app for athletes to record the path, speed, distance, and elevation of a given walk, run, bicycle run, or any other outdoors activity in which moving from one place to another is involved. There are many smart phone applications out there that can be used to collect GPS waypoints and tracks, this task sheet covers how to collect GPS tracks with the myTracks - The GPS - Logger iOS app and how to export the tract as a GPX file. Trust the accuracy of your ITIL 4 exam preparation with a training organisation officially accredited by PeopleCert on behalf of AXELOS. The calculation of the ascent and descent values is slightly different as GPS elevation values are even less accurate. The best value ITIL 4 Foundation Exam Preparation available from the leading online Accredited Training Organisation and AXELOS partner: Zindiak Limited. You can enable this in the recording settings. In general, this results in shorter tracks. Even if you stay at one point, the GPS position may change slightly.Īs of version 7.2, myTracks offers both a smoothing algorithm and a detection of whether the iPhone is at rest. myTracks simply sums up the distances between these track points. When I left for hiking, I was not able to track my movement anymore on the City Map2Go App and another app called MyTracks. ![]() ![]() When walking in a straight line, one GPS location may be to the left of your exact position and the next to the right. So each GPS track point has some inaccuracy in latitude, longitude and altitude. The general problem is the inaccuracy of GPS. When you select a location of interest (including features, search results, and dropped pins), a Directions action becomes available. If you compare the track length recorded by myTracks or the ascending and descending elevation values to those recorded by other apps, you may notice a discrepancy. While Field Maps doesnt generate routes or provide directions in the app, it does pass locations to routing apps including ArcGIS Navigator, Apple Maps, and Google Maps.
