GPS/TDOA Hybrid Location Algorithm Based on Federal Kalman Filter
Generally, accuracy of GPS(Global Positioning System) is higher than that of cellular network. But in tall building urban area or indoor, relatively weak GPS signal makes the positioning unstable and inaccurate. TDOA(Time Difference of Arrival) is one of the most widely used positioning methods in cellular mobile communication systems, but its accuracy is not high enough to meet the growing dem...
متن کاملEvaluation of Tdoa Techniques for Position Location in Cdma Systems
The Federal Communications Commission (FCC) has adopted regulations requiring wireless communication service providers to provide position location (PL) information for a user requesting E-911 service. The Time Difference of Arrival (TDOA) technique is one of the most promising position location techniques for cellular-type wireless communication systems. The IS-95 Code Division Multiple Access...
متن کاملKalman tracking based on TDOA for UMTS mobile location
The TDOA approach is qualitatively different in networkbased positioning systems from the mobile-based positioning systems. In network-based systems, the TDOAs are the time difference of arrival of a signal sent by the UE (User Equipment) and received by several BSs (Base Station). Conversely, in mobile-based systems the TDOAs are equal to differences in pairs of BS TOAs (Time of Arrival) measu...
متن کاملData Compression Trade-offs for Tdoa/fdoa Geo-location Systems
The research results reported on here focus on new data compression methods that can enable Air Force systems to more rapidly and effectively share data for precision geolocation of RF emitters. The work was focused in four areas: (1) New Theoretical Results: We extend the previous rudimentary insight into how to use data compression to accomplish trade-offs between the sequence of tasks in a l...
متن کاملHybrid TDOA/AOA Geometrical Positioning Schemes for MS Location Estimation
Abstract To achieve more accurate measurements of the MS location, it is possible to integrate many kinds of schemes. In this paper we combine time difference of arrival (TDOA) from three base stations (BSs) and angle of arrival (AOA) information at the serving BS to give location estimation of the MS. Based on the non-line-of-sight (NLOS) environments and the knowledge of NLOS error statistics...
