How to test CW25-TIM GPS module that is connected through RS232 ?

[puneetnepsam]

CW25-TIM GPS is connected to our controller through the RS232 interface.
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

Re: GPS module testing

what do you want to test?

1. sensitivity -- you need simulator
2. 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,
