Application of gravity deflection compensation to a Kearfott High Accuracy INS (HAINS) is summarized. Flight test data collected at the Central Inertial Guidance Test Facility is analyzed to identify the gravity deflection contribution to overall system performance. The paper discusses the general design of the HAINS INU. It also reviews the analysis procedure employed to evaluate gravity effects and includes detailed analytical results for a number of flight trajectories showing resulting system performance after removal of gravity-induced errors. The conclusions are generally applicable and provide motivation for introducing gravity compensation algorithms into HAINS Quality Systems.
