‘r’ – Transmitter Mounting Frame
Syntax:
r
station
,[
A
],[
E
],[
R
]<>
or
r
station
<> to read back the current transmitter mounting frame
Purpose:
This command allows the user to modify the mounting frame coordinates of the
transmitter relative to a particular receiver. It is basically a non-physical rotation
of the transmitter and becomes the new orientation reference for the specified
receiver’s measurements. The command parameters are as follows:
station
the station to be defined
A
azimuth mounting frame angle
E
elevation mounting frame angle
R
roll mounting frame angle
Relatives:
None.
Default:
0,0,0
Example:
If there was a requirement to mount the transmitter upside down, (more
mechanically feasible) then the following command should be used.
r1,0,0,180<>
The orientation measurements for station 1 will now look as if the transmitter had
not been mounted upside down.
