Hyperspectral instrument leverarm information

Leverarm calculation

The leverarm gives the 3-dimensional vector from the sensor focal point to the point where the GPS positions are referenced. This is measured using metres in a cartesian coordinate frame where (since 2011): X is positive along tail to nose, Y is positive to starboard, and Z is positive down.

Since 2011 the leverarms for the hyperspectral instruments use the same reference point as the LiDAR does (on a virtual PAV 80). This allows the same navigation data to be used for all the instruments on the aircraft. The leverarms are calculated from measurements made by the survey company.
