to see if the GPS antenna
is locked on the DGPS satellite signal. If it
is not locked on DGPS continue waiting. De-
pending on location it can take 15 minutes or
longer for the GPS receiver to lock on to the
satellite signal and obtain DGPS accuracy. If
GPS position is not working see the Trouble-
shooting section.
7. After the GPS receiver is locked on satellite sig-
nal, set the current Pivot Point position.
(a) Push the
Set Coordinates to Pivot Point
button to set the Pivot Point position to the
current position.
(b) Record the Pivot Point GPS Latitude and
Longitude on the inside of control panel door.
8. Set the Distance to GPS (the distance from pivot
point to GPS tower box). See Figure 24-1.
(a) Select the
Length to GPS (ft) field and enter
the length from the pivot point to the GPS
antenna. Do not enter the pivot length.
The default is 1320 ft (402.3 m), and the
range is 10 to 6554 ft (3.0 to 1997.6 m).
(b) Select the field and enter the plus
tolerance which is the acceptable satellite
data retrieved outside the GPS receiver.
The default is 50 ft (15.2 m) and the range is
10 to 6554 ft (3.0 to 1997.6 m).
A setting of 50 ft (15.2 m) or more is rec-
ommended to allow for variation in the GPS
signal if Wide Area Augmentation System
(WAAS) is unavailable.
(c) Select the Radius - field and enter the minus
tolerance which is the acceptable satellite
data retrieved inside the GPS receiver.
The default is 50 ft (15.2 m) and the range is
10 to 6554 ft (3.0 to 1997.6 m).
A setting of 50 ft (15.2 m) or more is rec-
ommended to allow for variation in the GPS
signal if WAAS is unavailable.
