Remote Gps Antenna/Receiver Connection; Table 21: Gps Start-Up Time - Motorola MTS LiTE Installation, Configuration And Basic Service Manual

Initial Start
This is the first time an MTS is powered on or after the almanac or position information has been
erased from non-volatile memory (NVM). The site needs to locate 4 satellites and then train the
reference oscillator from an unknown state.
Warm Start
The MTS has been previously powered up and the non-volatile memory contains valid almanac and
position information and the reference oscillator was trained before starting the site. The times quoted
are for a power-off restart. A software restart will be slightly faster.
Soft Restart
This is an MTS restart, where power is maintained during the reset, for example, the remote MTS
restart after software upgrade. The GPS receiver will continue to track satellites during the MTS restart,
thus eliminating the search for satellites phase of start-up.
