Satellite signals travel through our atmosphere, which slows them down slightly. The Flagstaff Summit Road is an out-and-back, but notice how the part of the route with the black circle is some 50 meters off the road itself. fit file from a Garmin Edge 500 with older firmware, shows measurement error. Measurement Error: If you’ve ever downloaded a GPS file only to find your path on the map is parallel to a road but not actually on it, that’s measurement error, as shown in this Garmin Connect file from a recent ride to test GPS accuracy. Based on the time difference between when the wave was sent and received, a GPS unit figures out how far away each satellite is and uses that info to pinpoint your location-a process known as trilateration. Those satellites send out radio wave signals picked up by your device.
GPS devices gather data from a group of 27 satellites that orbit Earth twice a day, following exact trajectories such that, at any given time at any given location on earth, at least four are visible. Understanding the reasons why GPS discrepancies happen might help you eliminate some error, or learn to live with it until a better alternative arrives. By using GPS, “we operate on a system that’s inaccurate to some degree,” she says.

“Each difference has a different driver,” explains pro cyclocross racer Elle Anderson, who, as part of Strava’s customer support team, deals with these questions every day. GPS lies, if we want to call them that, derive from a number of issues and affect metrics from distance to average speed to elevation gain. For Android, simply tap the pin icon at the top.Play icon The triangle icon that indicates to play
Then, for iOS, tap the gear icon to bring up route options menu followed by Pin This to pin the route. To pin a route on the RideWithGPS app, select your desired route from your route list in the app. This will sync the route the next time the sync process (outlined above) is completed. Click the a small “pin” icon above the route name in the column on the right of the route map to pin the route.

If Wi-Fi is not available, once a route created or pinned in your RideWithGPS account, it is loaded into the ELEMNT App, and can be synced via Bluetooth to your ELEMNT/BOLT/ROAM. Sending Routes to an ELEMNT via Bluetooth ® Once synced, simply select a route to start navigation with Turn by Turn directions ( cues required).Sync time depends on the number of routes in your RideWithGPS route library and typically takes just a few minutes. Note: RideWithGPS routes are not synced automatically, so this process must be repeated for new routes to appear.
Any pinned routes are displayed with a star. All routes which appear under "My Routes" on the RideWithGPS website will appear on this page of the ELEMNT /BOLT/ROAM, as shown below.
