Regarding connection of GPS module to Google maps

Submitted by Bharath on

Sir,
By using two GPS module we can get the coordinates of those Arduino boards. But I want to know how both Arduino recognize that any of them are in there prescribed range and send signal to each of them. I am trying to measure there distance in Google maps for a long distance like in kilometers range. So how to connect them to Google maps. Do we also need GSM module for both boards.
