GPS Integration Receiver-Programmable (GPS-PRO) Open Architecture Receiver Design and Unique Applications

Khien B. Nguyen, John G. Haiges

Abstract:	With the widespread applications of GPS and the ever changing and evolving GPS requirements and capabilities, both in the commercial and military markets, there is a need for a flexible open architecture GPS receiver that would support laboratory development testing of GPS receiver design concepts, integration schemes, and GPS applications. The experience of the Central Engineering Activity (CEA) GPS Laboratory at NRaD San Diego supports the need for such a receiver. The special investigations and R&D GPS projects conducted by NRaD frequently require novel integration or data collection capabilities. These would only be readily available in a flexible receiver with a high degree of adaptability to the laboratory’s ever-changing needs. The GPS Integration Receiver-Programmable (GPS-PRO) receiver, which utilizes an open hardware and software architecture, provides the necessary flexibility to perform this function. The GPS-PRO uses Commercial Off-the-Shelf (COTS) hardware, an open architecture for external sensors, external communications and control, digital control, open software architecture, functional breakout points, and an upgradable daughter board concept for application specific systems. Such a receiver configuration provides the flexibility to interchange or insert new hardware or software modules in order to evaluate their performance in a controlled environment or provide an integrated system solution. The GPS-PRO flexible (programmable) functionality allows for its use as a design tool for R&D and hardware in-the-loop testing, application specific tailoring for low cost, small size customer demands, while providing benchmark performance capabilities.
