MEASURING GNSS LEVER ARM OFFSETS
To accurately position your LIDAR data, the position from the GNSS antenna must be transferred to the
onboard positioning system. This is done by using lever arm offsets. If your system is mounted on an
M600 with the GeoCue integration kit, the offsets have been preset by a GeoCue technician and should
not need to be modified. If you are not using the GeoCue integration kit, or are installing the True View
on a different aircraft, you will need to measure the offsets, then log in and enter them into the APX-15
(Figure 41). The position is referenced to the APX-15, which is enclosed inside of the housing and
cannot be physically measured to. Therefore, you must measure to a physical point on the True View
frame, then add or subtract offsets to the APX-15. The instructions below explain the physical reference
points to measure to, and the offsets between those points and the APX-15.
An assumption is made that the True View sensor will be aligned with the heading of the aircraft, and
the aircraft will fly forward during data collection. The True View battery compartment is the front of
the LIDAR sensor, so it should face the heading (front of aircraft).
