EPHEMERIS HOLD OPTION (@@AA)
In normal operation the GPS receiver automatically acquires and uses
the latest satellite ephemerides from the GPS satellites. When the GPS
receiver detects a new ephemeris data set, it collects the new data and
immediately begins using the new data.
If the user enables the Ephemeris Hold Option the GPS receiver holds
the current ephemerides in memory and will not collect new ephemerides
from the GPS satellites. With ephemeris hold enabled, the GPS receiver
will only accept and use new ephemeris data input via the RS-232 port.
Ephemeris Hold Option is always disabled at power-on.
Default value: Disabled
