GPS Satellite Acquisition
Operating and Programming Guide 5-9
Facilitating Initial Tracking ______________________________
This command sets an approximate date for faster initial GPS acquisition.
Following powerup, the Receiver obtains the current date from satellite data.
This process occurs automatically. Providing an approximate date, however,
reduces the time to initial GPS tracking by assisting the Receiver in finding
satellites.
