Experiences of GPS Attitude Determination within a Helicopter Pod

M. Elizabeth Cannon, Manfred Haverland

Abstract:	The paper describes the navigation system of a helicopter pod designed for wind and turbulence measurements. For this application, the navigation package must provide position, speed, attitude and turn rates with a rate of 50 Hz. ln order to achieve the required performance GPS, inertial and other measurement systems are combined. Since the helicopter pod is designed for shipbome operation, alignment of the inertial system is a difficult task and cannot be solved using standard methods like magnetic flux sensors. Therefore, in addition to the standard navigation package, a GPS interferometry system was implemented for attitude determination. The development, implementation and testing of the GPS attitude determination system in static and land kinematic mode are discussed and results achieved to date are presented.
