Note

e basic conguration of the GPS system is 24 satellites orbiting the Earth at an altitude of 20,000 km with at least four satellites traveling in six dierent orbits. e GPS receiver acquires data from four satellites and calculates the latitude, longitude, altitude, and time. You can start measuring once the GPS positioning has been performed and this information has been received. You can receive more detailed GPS navigation data (satellite orbital information) if you wait 15 minutes aer initial GPS signal acquisition, which improves measuring accuracy.

However, note that GPS positioning is not 100% accurate or reliable at all times even with the more detailed GPS data because of atmospheric conditions and the usage environment.

Note AGPS - Reducing the GPS Positioning Time

You can reduce the GPS signal acquisition time by connecting the device with a smartphone and then retrieving GPS satellite information from a network server. Refer to the Epson View website for more information.
