Detection and Location of GPS Interference Sources Using Digital Receiver Electronics

Alison Brown, Sheryl Atterberg and Neil Gerein

Abstract:	GPS is now being used to provide positioning and timing information for a number of applications where it is essential that the accuracy and reliability of the GPS information can be assured. These include safety of life systems, such as aircraft navigation during approach and landing, transportation applications such as railroad control, and also critical commercial applications such as mobile communication networks where GPS timing is used. The susceptibility of the GPS signals to interference is of concern to the GPS user community. Because of the low received power of the GPS signals, outages can easily occur due to unintentional interference, and the potential exists to deny access to the GPS signals using easily obtainable RF hardware. In this paper, an advanced GPS receiver is described that includes the capability to detect and locate GPS interference sources. This enables prompt action to be taken to protect the integrity of the GPS signal sources for safety of life or system critical applications of GPS.
