Chapter 5 - I/O Commands
ALMANAC STATUS MESSAGE (@@Bd)
Applicability: M12+ Timing and Positioning Receivers
This command requests almanac status information corresponding to the satellite almanac data
currently 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.
Legacy Code Compatibility: The @@Bd command was implemented in an identical fashion on
Motorola VP Oncore receivers.
