Figure 4-1. GPS Info
The GPS Info screen includes status information for the current number of satellites in view, time
zone, antenna, and the current time and date.
The following list describes the type of information shown on the GPS Info screen:
l
GPS Info D 00:00:36 — The current time and date. The time is shown in military time (24
hours) and uses the HH:MM:SS format to represent hours, minutes, and seconds. The date is
shown in MM/DD/YYYY format to represent the month, day, and year. The letter shown just to
the right of
GPS Info is used to troubleshoot an issue with the unit's GPS lock.
l
Ant: OK 00/00/00 — The antenna status. If the antenna is disconnected or loose, the status
message Antenna OPEN displays. If the antenna is shorted, the status message Shorted
displays.
l
3D Fix SV 07/07 — Shows whether a 2D or 3D GPS lock has been obtained and the number of
satellites seen by the unit. In this example, 07/07 refers to 7 satellites in view out of 7 possible
satellites. A 2D lock requires 3 satellites, while 3D lock requires at least 4 satellites. If the unit
sees an insufficient number of satellites, move the antenna until at least a 2D lock (preferably a
3D lock) is achieved.
If no satellites are seen, the message Acq Sat appears in the display on the left side. The
message 3D Fix displays when the unit has established communication with at least four
satellites.
l
UTC Setting: -06 — The Universal Time Constant (UTC) that is used by the GPS system.
IMPORTANT:
GPS lock is not needed for the GPS360 to operate. The internal clock updates as
soon as the internal GPS locates satellites. For synchronized interruption or interference, make sure
the antenna position enables at least a 2D lock.
