Abstract

This paper discusses the simulation and flight test results of an integrated dual airborne laser scanner (DALS)/inertial navigation system (INS) navigator onboard Ohio University's DC-3 aircraft over Athens, Ohio. The use of two airborne laser scanners, integrated with an INS form an alternative means of navigation in non-GPS and unknown terrain environments. In these environments the usual integration of GPS and INS will no longer be a viable option. This paper will address both a feed-forward and a feedback coupled method without an available terrain database and show flight test results onboard Ohio University's DC-3.
