US 2006/0234641 A1 · System for using an existing cellular network to detect incidents of GPS jaming

Abstract

A system for detecting incidents of GPS signal jamming utilizes one or more cellular telecommunications networks where GPS signals are received at various geographically dispersed base stations for timing or synchronization purposes—e.g., certain CDMA-based mobile phone networks. Each base station is outfitted with a data routing subsystem that routes data relating to interruptions in the received GPS signal, as detected by the base station, to a real time national database. The database stores and processes the received data, and is configured to be accessed by government or other officials for assessing GPS interference across the geographic area covered by the cellular network(s). The GPS interruption/interference data may be graphically displayed, and it may be correlated with other relevant data.

Claims20

Dependent claims

A system for detecting global positioning system (GPS) signal interference at a cellular network base station, said system comprising:

a data router configured to cause interference data to be routed to a database if the base station issues a GPS alert, wherein the interference data relates to GPS signal interference detected at the base station.
