NMEA Time sets the PC clock to the time from the GPS receiver. The software uses GPGGA, GPRMC 
or GPZDA NEMA sentences to obtain time. Time can be set with additional accuracy by using the 1PPS 
signal from the GPS receiver and optional interface circuitry.

WinOncore12 Software for GPS Receivers (Free)

 

http://www.motorola.com/ies/GPS/products/winOncore™12.html

 

WinOncore12 is distributed with Motorola's Oncore™  evaluation kits and is designed for evaluation and 
testing of Oncore™ GPS receivers. This utility aids the user in initializing and operating the Oncore™ 
receiver. The software includes diagnostics, satellite signal strength readouts, satellite positions, 
navigational information, plotting and printing data from the receiver; and recording and replaying data 
files.  
 
NOTE: You should first initialize the receiver using the Setup Receiver button: 
 No response will be available unless this is done first!
