Interferometric GPS Attitude: A Stochastic Error Model

Abstract

During the August 1992 sea trial off the west coast of Vancouver Island, onboard the CFAV Endeavour, data was collected from a relatively new type of GPS (Global Positioning System) receiver which measures attitude (heading, pitch and roll) as well as the usual GPS measurements of position and velocity. GPS attitude has the potential to provide rapid and precise attitude for a relatively low cost. Attitude is conventionally determined using inertial equipment, which for precise work is very expensive, large and requires a long settling time after turn-on. The receiver being evaluated on this sea trial was an Ashtech Three-Dimensional Direction Finding System (3DF). This report provides some general background on GPS attitude technology, presents the attitude errors observed during this sea trial and characterizes these errors as stochastic processes, Navigation, Global Positioning System, GPS, Attitude, Interferometric, Sea Trial, Error Model.
