Abstract:	In this paper a system design is described for a fault tolerant GPS/Inertial inteerated svstem suitable for use in future launch vehicles (FLV). ?I?o incriase the robustness of the navigation system an inte rated GPS inertial fault-tolerant system design is proposed, %i I, T s approac allows dual failures to occur in any component of the system without affecting the performance of the FLV navigation or guidance. Three levels of FDI are proposed to detect failures in the inertial instruments, the GPS receivers or the integrated navigation solution. The design of the fault tolerant INS and GPS systems under consideration for FLV applications and the proposed implementation of the FDI algorithms are described in this paper. Simulation results on the performance of the proposed algorithms are also included to demonstrate the benefits of this approach for FLV applications.
