GPS Jamming in A Laboratory Environment

Gregory D. Rash

Abstract:	Most modem weapon systems and aircraft depend, in part, on the Global Positioning System (GPS) for navigation. This reliance on GPS navigation dictates that laboratory test facilities be equipped to create realistic GPS jamming environments able to verify compliance with jamming specifications. Engineers at the Naval Air Warfare Center Weapons Division (NAWCWPNS) have designed and built a GPS jamming system for laboratory use to test GPS system jamming performance. This paper identifies and discusses issues related to implementing a GPS jamming system in a laboratory test environment. These issues pertain to jamming accuracy requirements, as well as important jamming system design parameters and how they may affect jamming system performance. An example of the Navigation Laboratory jamming system is presented. It addresses fabrication issues, data requirements, error handling, local and remote operations, and how to attain high accuracy and repeatability during the generation and measurement of jamming.
