Prototype Testing of an Integrated Doppler/GPS Navigation System

James L. Maida

Abstract:	The AN/APN-217(V)5 consists of a Doppler Radar and Global Positioning System (GPS) receiver that are combined into a fully integrated navigation system. The production GPS will be a dual channel, P-code, Ll/L2 receiver which is physically embedded into the existing APN-217 Doppler form factor. The test results obtained from the CIA-Code, L1, prototype receiver were very favorable. In assessing the data and comparing it to the overall system design and test objectives, it can be seen that the system performance was excellent and the results showed design goals were met. The results demonstrate that we have been able to achieve an overall position accuracy in the range of 20 meters SEP (Spherical Error Probable) and velocity accuracy on the order of 1 meter/second with the prototype system. This paper presents the results obtained during both ground and flight tests of the first prototype version of the APN-217(V)5. The paper also looks at a brief synopsis of the system's history and development, as well as some of the overall design objectives and mission applications. Basic system level design and functional operation will also be discussed to support the overall understanding of the system concept.
