Can anyone please tell how to test that GPS module.? and please tell what is meant by the 1PPS signal of the GPS. By reading that signal through the software, can we test the GPS? Thanks in advance Puneet

Timing -- PPS (pulse per second), coneect it to a oscilator or a timing source to measure accuracy. 3. CEP -- log position data. .... Hpoe this helps in deciding, BRM
