Low cost inertial/GPS integrated position and orientation systemfor marine applications

This paper describes the Low Cost Position and Orientation System (LCPOS), comprising the integration of a low cost “tactical grade” inertial measurement unit with GPS position, velocity and heading aiding data. LCPOS was designed to be a cost-effective alternative to a high performance costly ship INS (SINS). The demonstrated accuracy of the LCPOS integrated navigation solution is comparable to that of the SINS
