I was wondering if could get the PPS signal from the Sierra Wireless AirPrime MC7750 GPS module to synchronize with my LIDAR. Is there a pinout in the module that i can maybe solder into to get the PPS signal or is there software methods that I can use?

Any help would be appreciated.

Thanks  
Raj

Raj,

Unfortunately there is no PPS signal out of any of the MC units, the only information is through the dev/ttyUSB NMEA port and AT commands.
