Development of a TRN/INS/GPS integrated navigation system

Abstract

The National Aerospace Laboratory (NLR) has been awarded a contract by the Netherlands Ministry of Defense for the investigation and development of a TRN/INS/GPS (terrain reference navigation system/inertial navigation system/Global Positioning System) integrated navigation system. The integrated system should be capable of providing degraded modes. The three navigation sensors and a dedicated processing unit (for data merging) were configured around a MIL-STD-1553B digital data bus. Due to the inherent complexity of the integrated navigation system, much emphasis was given to careful testing of this system. Initial flight test results indicate that the integrated navigation system showed good performance, even when the performance of the individual sensors was deteriorated.<>
