ALMANAC STATUS
This command requests almanac status information corresponding to the currently
used satellite almanac data stored in RAM. The GPS receiver continually captures a
complete new almanac to internal RAM while tracking satellites. If an existing
almanac is stored in RAM on power-up, satellite visibility information will be
available immediately. If no almanac data is stored in RAM on power-up, the
receiver will download a new almanac and then compute satellite visibility
information.
Almanac data is stored in memory only while main or battery back-up power is
applied.
