The Design of Integrated Navigation System Based on MBSE

This paper proposes a schema for the design of an integrated navigation system including two inertial navigators, two Global Position System (GPS) receivers and a Doppler velocity sensor(DVS) with applications of Model Based Systems Engineering (MBSE). First, requirement analysis and function analysis are accomplished with Rhapsody. Then the architecture of the system is designed to identify the subsystems and allocate the use case to the subsystems. Finally, the results of simulation show that the design of the system can satisfy the system requirements proposed previously.
