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.
