EPHEMERIS DATA INPUT
This command will cause the receiver to accept satellite ephemeris data input via
communications port 1 (pin 2). The receiver keeps the ephemerides decoded from
all satellites in RAM, as long as the 3v BATT voltage is applied to the receiver and
the ephemerides are still valid (t-toe < 4 hours).
The input format is identical to the format output by the previous Oncore Receivers
using the output ephemeris command. This allows 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.
