Model:
GV: Laseref IV P/N HD2001; C130: Laseref V-SM P/N YG4037AB07
Measurements Provided:
Aircraft position (Latitude, longitude, baro-inertial altitude), N-S, E-W ground speeds, baro-inertial (pressure damped) vertical aircraft speed, and aircraft attitude angles (pitch, roll, true heading/yaw).
Measurement Characteristics:
Position and ground speed data subject to Shuler Oscillation drift errors until blended with GPS data in post processing. Additionally there are "transport delays" and digital filtering in the IRU computer that are accounted for in post processing to align measurements with other recorded data.
