This process normally only needs to be performed once.

Perform this process if the device has not been used for several months.
Note
The basic configuration 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 different orbits. The 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 after 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.
