ALMANAC STATUS MESSAGE (@@Bd)
This command requests the almanac status information corresponding to
the currently used satellite almanac data (in RAM), as well as the
almanac data currently stored in receiver nonvolatile memory
(EEPROM). The GPS receiver captures a new almanac to internal RAM
first and uses this data immediately to compute satellite visibility
information. The receiver also copies the RAM data to nonvolatile
EEPROM using a slow background process. Consequently there is a
delay between the receipt of a new almanac and copying the new one to
EEPROM. The user is given status information on both almanac data
sets.
