Abstract

Herein, we presented the design result of the GAK GPS/INS system. The navigation system has dual-coupled methods due to the installation configuration of the GAK. Before the GGB jettison, GGB is navigated in loosely-coupled GPS/INS navigation, while a tightly-coupled GPS/INS navigation is used after jettison. We also described the test methods to evaluate the navigation performance. With fourteen monitoring parameters related to the navigation Kalman filter and PDU, we determined the status of loosely-coupled GPS/INS navigation systems before the GGB jettison. After jettison, we proved that the navigation system met the performance requirement using the DGPS post-process method.
