A General Observation Matrix for Attitude Error Estimation with an Offset GPS Antenna

JUN 92

80 pages

Authors: C. A. Bass; C. Karmokolias; A. Khatri; NAVAL COMMAND CONTROL AND OCEAN SURVEILLANCE CENTER RDT AND E DIV SAN DIEGO CA

In conventional integrated GPS/INS navigation systems, attitude errors are estimated through correlation to, primarily, velocity errors. This correlation develops due to the coupling of the attitude errors to the velocity errors via the presence of specific forces. Other GPS-based attitude measurement techniques typically employ multiple antennas and special receiver hardware. An alternate approach to attitude estimation is proposed. This report exploits the attitude (and attitude rate) information inherently present in ...
