RaceCapture GPS: Difference between revisions

Revision as of 20:01, 5 February 2016

GPS is a complex and sensitive system that can be affected by many different factors. Number of satellites, nearby radios, weather, terrain and obstructions all affect GPS data. To get the best GPS signal and quality, use these tips.

Use 10Hz for best balance of performance / accuracy

If you are at a track that has lots of elevation changes, obstructions (bridges, hills, buildings, etc), keep the update rate at 10Hz.

25 and 50Hz can be used when you have clear horizon to horizon view all around, with minimal obstructions and terrain- such as flat plains or desert terrain.

Clear view of sky

Make sure the GPS antenna is mounted in a location with a full view of the sky. The best place is on the roof of your car, or under the front or rear window.

Away from transmitting devices

GPS antennas can be affected by other transmitting devices. ideally, place the GPS antenna as far away from them as possible. If you notice GPS accuracy issues while an in-car radio is transmitting, check the frequency that the radio is broadcasting on. If necessary, change to a different broadcasting frequency / channel.

Use latest RaceCapture/Pro firmware
