Sensor Position
The measurement (in mm) of the vector offset from the origin of the sensor mounting frame, which must be stated (e.g. gimbal, platform, or ECEF coordinate system), to the origin of the sensor perspective center, L. Offset vector describes the position of the sensor perspective center relative to a gimbal position (if any) which, in turn may be referenced to the platform coordinate system; or the offset may be given directly to the platform coordinate system, if known. Conditional in the case where a sensor may provide position information directly referenced to, say, an ECEF system.
