determine its location. Some other terms you will encounter on the GPS Signal Status screen
include:
Antenna Sense = SSSSS
SSSSS reports the status of the antenna sense circuit. There are three main flags (OK, Over
Current, and Under Current). The three flags are described here:
OK Flag
The OK flag is displayed if both antenna sense bits are cleared. This indicates that the antenna
is drawing current within the normal range.
Over Current Flag
This flag is displayed if the over current bit is set. This indicates that too much current is being
drawn through the circuit and the overload protection circuit is limiting the feed current. The
receiver will attempt to continue the normal acquisition and tracking process regardless of the
antenna status.
Under Current Flag
This flag is displayed if the undercurrent bit is set. This indicates that little or no current is being
drawn through the circuit, which may be due to a disconnected antenna, a severed antenna
cable or a damaged antenna. The receiver will attempt to continue the normal acquisition and
tracking process regardless of the antenna status.
Undercurrent indication < 8 mA
Overcurrent indication > 80 mA
NOTE:
This condition will also be present if a GPS antenna splitter that does not contain a
load to simulate an antenna being present is being used.
Latitude = [N:S][DD MM SS.SSSS]
Longitude = [E:W][DDD MM SS.SSSS]
Where: N = North latitude
S = South Latitude
E = East Longitude
W = West Longitude
D = Degree
M = Minute
S = Second
Quality = QQQQQ
QQQQQ = Result of GPS qualification, either PASSED or FAILED. The GPS signal is
considered qualified when at least one satellite is received having a vehicle ID of at least 4 that
are available for Position Fix Usage while in the normal mode of operation (Or at least 1 satellite
that is available for position fix when the unit is single satellite mode).
Information on each satellite the receiver is currently tracking is presented in table form. The
table columns are described below:
CHANNEL = Channel Number of the GPS receiver, 1…12
VID = Vehicle (satellite) Identification Number, 1…37
