Abstract:	A GPS-SBAS Receiver is developed around a Digital Signal Processor with optimize usage of hardware and software in the system. The receiver is designed and engineered for use in avionics application after FAA TSO certification. Important aspects of the receiver are reliable hardware and safety features. The failure analysis of the receiver hardware for various navigation functionalities shows acceptable performance. The power-on self test and continuous online tests to detect hardware failure enhance the safety and reliability of the equipment. Additional hardware to detect failure improves the test coverage of the equipment. Comprehensive Receiver Autonomous Integrity Monitoring (RAIM) ensures reliable performance and safety of the system while in use in an aircraft anywhere in the world during the en-route, terminal and non-precision approach phases of the flight.
