Date and Time Commands
8.9.1
Set Receiver Time
Command:
yyyy:MM:dd:hh:mmTS
. . . TS sets the receiver (UTC) time when not locked to the GPS. The
command is ignored when the Model 1095A/C is locked to satellites.
When the receiver is initially activated, and has not locked onto satel-
lites, acquisition time may be improved by giving the clock an initial
estimate of UTC time, which it can use (with stored position and
almanac data) to determine which satellites and Doppler shifts to use
in acquisition.
