VP ONCORE COMMAND REFERENCE

INPUT EPHEMERIS DATA (@@Bf)
This command will cause the receiver to accept satellite ephemeris data
input via the serial port. The receiver keeps the ephemerides decoded
from all satellites in memory as long as backup voltage is applied to the
receiver, and the ephemerides are still valid (t-toe < 4 hours). However,
the ephemeris data that the user inputs via the serial port is only
remembered until the next time the receiver power is cycled, or until it is
replaced as a normal part of decoding new ephemeris data from a
satellite. This is true even though backup power may have been applied
during the receiver off period. The @@AA command
can be used to
prevent the receiver from replacing the user input ephemeris with new
data decoded from the satellites.
The input format is identical to the format output by the receiver for the
output ephemeris command to allow the same ephemeris output file to
be used by the receiver for an ephemeris input file. The receiver echoes
the input ephemeris data format message so the user can validate the
ephemeris data with the new user supplied ephemeris upon completion
of the receipt of a valid ephemeris.
