Figure 4. Connection diagram for the RT on the Survey Trolley
Note: The connection is shown here with the SATEL radio option. The Freewave and other radio
options are similar.
The RT will need to be configured correctly for use on the Survey Trolley. Table 2 lists the critical
configuration parameters that should be used with the Survey Trolley. Other parameters can be left at
the default values.
Table 2. RT configuration on the survey trolley
Parameter Setting
Orientation Default settings: y-axis right; z-axis down
Primary Antenna Behind 0.230; left 0.075; above 1.520; overall accuracy 0.01
Dual Antenna No
Initialisation Speed 1 m/s
Displace Output Ahead 0.125; right 0.105; below 0.095
This configuration sets the measurement point for the survey at the centre of the wheel contact patch
for the front right wheel of the Survey Trolley. It is normally easier to survey using a wheel as a
marker rather than a point on the Survey Trolley.
A suitable configuration for the Survey Trolley is installed in the folder:
C:\Program Files (x86)\OxTS\RT-Range\Survey Trolley
This can be installed using NAVconfig.
To initialise the RT on the Survey Trolley push the Survey Trolley in a forward direction at a speed
exceeding 1 m/s. You should be going straight when the RT initialises. Afterwards you should make
some turns, accelerate and brake so that the RT can estimate some of the errors in its sensors.
The battery recommended for use with the Survey Trolley is a lead-acid battery. This should be kept
in a charged state; it should be recharged immediately after each use. Lead- acid batteries tend to
degrade if left in an uncharged state.
