‘B’ – *Boresight
Syntax:
B
station
<>
Purpose:
This command causes the tracking receiver to be electronically aligned in
orientation with the user system coordinates. This results in azimuth, elevation
and roll outputs equal to the boresight reference values (usually 0,0,0 which is the
system default) at the current orientation. The tracker then produces outputs
relative to this reference. Any receiver orientation can be designated as the zero
orientation point. The command parameter is defined as:
station
the number of the station to be boresighted.
Relatives:
b, G
Default:
The zero orientation condition occurs when the receiver orientation corresponds
to the transmitter orientation.
Example:
The receiver may be mounted on a person’s head to measure where it is pointing.
When the subject’s head is looking at a given object, the user may want the
system angular outputs to be zero. The user can designate this receiver orientation
as the zero orientation by sending the boresight command:
B1<>
This results in azimuth, elevation, and roll outputs of zero at this orientation. As
the subject’s head moves away from the boresight point, the orientation angles are
still measured relative to the transmitter, with the zero points shifted to the point
where the boresight occurred.
