Simulator Validation Testing of the WAAS Verification Receiver

Ronald L. Brinkley and Rajnish Aggarwal

Abstract:	The use of the Global Positioning Systems (GPS) as a sole means of navigation requires the implementation of augmented systems for improved accuracy and integrity. The Federal Aviation Administration (FAA) is developing the Wide Area Augmentation System (WAAS) to be used by commercial navigation for enroute, terminal, nonprecision approach, and category I precision approach. Two important components, a verified set of Minimum Operational Performance Standards (MOPS) and a validated WAAS MOPS compliant GPS/WAAS receiver, are required as part of the Verification and Validation (V&V) testing of the WAAS system. The WAAS Receiver Test Tool (WRTT), a GPS/WAAS RF signal simulator, was developed at NAWC-AD for the purpose of validating the WAAS MOPS and the newly designed WAAS Verification Receiver (WVR). This paper presents an overview of the WRTT, the test methodology, data analysis and results from the validation testing of the WVR.
