‘G’ – Boresight Reference Angles
Syntax:
G
station
,[Az
ref
],[El
ref
],[Rl
ref
]<>
or
G
station
<> to read back the current boresight reference angles
Purpose:
This command establishes the bore-sight reference angles for a particular station.
When the system is boresighted with the
), the line-of-sight vector (Azimuth, Elevation, and Roll angles) will assume
these values. If all the optional parameters are omitted, the system returns the
boresight reference angles for the specified station as an output record of type ‘G’.
The command parameters are defined as:
station
the number of the station whose reference angles are to be fixed.
Az
ref
the azimuth reference angle.
El
ref
the elevation reference angle.
Rl
ref
the roll reference angle.
Relatives:
B, b
Default:
The system default boresight reference values are: 0, 0, 0
Example:
The user may wish to set the boresight reference values to an orientation that
corresponds with the application. For example, if the application required an
output of 0, -15, 0 following a boresight, reference angles should be applied with
the G command:
G1,0,-15,0<>
The boresight command (B1<>) will now cause the azimuth, elevation, and roll
data output to be 0, -15, 0 respectively.
