ANT DLY (antenna delay) displays the user-entered value that is used
to compensate for the propagation delay of the antenna cable.
Position
Position area of the status screen provides four types of information:
MODE (hold or survey), LAT (latitude), LON (longitude), and HGT
(height).
MODE indicates whether the unit is set to Hold or Survey position
mode.
When Hold is displayed, the unit’s antenna position has been provided
by the user, or the average position has been found after completion of
survey.
If the unit is in the position Hold mode, the LAT, LON, and HGT “held”
position coordinates will be displayed.
If Survey: 57.3% complete is displayed, for example, the Receiver is
set to survey mode trying to determine the position of the antenna. The
% value indicates the progress of the surveying.
At the beginning of a survey (0% completion), the following “estimated”
position coordinates will be displayed:
INIT LAT indicates the estimated latitude (North or South) position of
the unit in degrees, minutes, and seconds.
INIT LON indicates the estimated longitude (East or West) position of
the unit in degrees, minutes, and seconds.
INIT HGT indicates estimated height of the unit’s antenna, in meters
above the GPS ellipsoid for 58503B (in meters above mean sea level,
MSL, for the 59551A).
Once survey starts, the following “averaged” position coordinates will
be displayed:
AVG LAT indicates the average latitude (North or South) position of the
unit in degrees, minutes, and seconds.
AVG LON indicates the average longitude (East or West) position of the
unit in degrees, minutes, and seconds.
AVG HGT indicates average height of the unit’s antenna, in meters
above the GPS ellipsoid for 58503B (in meters above mean sea level,
MSL, for the 59551A).
