Measurements To Determine Potential Interference To Gps Receivers From Ultrawidebank Transmission Systems Ntia Report Series Ntia Repo

The goal of the Networking in Extreme Environments (NETEX) Program is to create a wireless networking technology that enables robust connectivity in harsh environments and support its integration into new and emerging sensor and Navigation receivers. The NETEX program is focused on the development of an improved physical layer for networked Navigations based on a family of new ultra-wideband UWB devices. UWB devices have the potential to perform a number of useful military Navigation and sensing functions that make them very appealing for warfighter applications. This report is one of a series of NETEX sponsored electromagnetic interference (EMI) test reports that detail the effects of interference from UWB transmissions on legacy military receivers. The purpose of this report is to document the results of EMI testing performed on the AN/ASN-163 and AN/PSN-11 GPS Navigation Receivers using an UWB signal generator as the potential interfering source. The AN/ASN-163 GPS Navigation Receiver is a five channel Miniaturized Airborne GPS Receiver. The AN/PSN-11 GPS Navigation Receiver is a five channel handheld GPS receiver. The report provides detailed descriptions of the UWB signal source and AN/ASN-163 and AN/PSN-11 operating modes, identifies the test methodology and test procedures and presents the results of the test events. The intent of these tests was to determine the relative susceptibility with respect to a standard RF interference signal of the AN/ASN-163 and AN/PSN-11 receivers for several of the primary operating modes of the receivers. Accordingly, a set of thirteen test waveforms were designed and injected into the receivers in order to be able to measure the interference effects. The results of the tests are presented in relative susceptibility plots and summarized in a data table.
