information. Under these conditions, the DG16 on average recomputes position in
10 to 15 seconds (hot start). If the almanac and ephemeris data are available in
battery-backed memory, but the ephemeris data are more than ten hours old, the
DG16 needs 30 to 40 seconds on average to compute a position (warm start). If
almanac and ephemeris data and a valid position are not available at power-up,
the DG16 computes position in 60 to 90 seconds on average (cold start).
On initial power-up or after issuing the $PASHS,RST (restore defaults) command,
the DG16 reverts to its default parameter settings. Enter the following three
commands to query the DG16 for the current parameter status:
1. $PASHQ,PAR (general parameters)
