Abstract :
This paper discusses the various aspects of using airborne laser scanners (ALS) in terrain referenced navigation (TRN) systems. The paper addresses the system performance of these new ALS-based systems and compares their performance to traditional terrain referenced navigation systems based on radar altimeter and baro-altimeter sensors. The TRN system comparison also includes an inertial measurement unit (IMU) error sensitivity analysis and a discussion on the requirements imposed on the information content in the terrain elevation database by the remote sensor. The paper will use flight test data collected with Ohio University´s DC-3Flying Laboratory in Braxton, WV to evaluate the various methodologies and analyses
