Abstract: In a method for refining a position estimate of a low earth orbiting (LEO) satellite a first position estimate of a LEO satellite is obtained with a GNSS receiver on-board the LEO satellite. The first position estimate is communicated to a Virtual Reference Station (VRS) processor. VRS corrections are received at the LEO satellite, the VRS corrections having been calculated for the first position estimate by the VRS processor. The VRS corrections are processed on-board the LEO satellite such that a VRS corrected LEO satellite position estimate of the LEO satellite is generated for the first position estimate.

Abstract: A method for acquiring positioning information includes receiving downlink data in a plurality of downlink slot frames, and receiving at a mobile terminal within one of the downlink slot frames, broadcasted global positioning system (GPS) orbital description data. The GPS orbital description data information relates to a first group of orbiting satellites within operable range of the base station (BS) providing the broadcasting of the GPS orbital description data. The method further includes performing GPS-based positioning for the mobile terminal based upon signaling received from a second group of a plurality of orbiting satellites in conjunction with the GPS orbital description data, such that at least one of the second group of the plurality of orbiting satellites is the same as some or all of the orbiting satellites of the first group.

Abstract: A forward link repeater frequency watermarking (FLRFWM) system and method that enable accurate position location of mobile stations in areas where repeaters are present by watermarking repeated signals with repeater information. A repeater watermarks a forward link signal with a (unique or non-unique) fast frequency modulation waveform watermark every time a signal passes through the repeater. A mobile station detects and/or identifies the fast frequency watermark on the forward link signal to determine repeater information that aids the network position determination entity or mobile station position location system in determining position location using AFLT and/or A-GPS systems. A forward link fast frequency watermarking system described herein achieves minimal impact on FL, AFLT, and GPS performance, good detection, identification and false alarm probabilities, short time-to-detect/identify, and good detection/identification sensitivity.

Abstract: In a method for providing location-based information over a network, a plurality of GPS reference data sets, corresponding to a plurality of respective local areas, are acquired at intervals such that each GPS reference data set is updated on a continuous basis. A plurality of aiding data sets are generated at intervals based on the respective GPS data sets, whereby each aiding data set is updated on a continuous basis. The generated aiding data sets are stored at intervals on a data-storing network server, whereby updated aiding data sets are available on a continuous basis for access by a requesting entity via communication with the data-storing network server.

Abstract: A method and apparatus for taking, transmitting, storing, processing, distributing and using data indicative of the position of a mobile object on the Earth's surface. More specifically, the latitude, longitude and altitude for the current position of a mobile object is measured, and the data for that position is periodically transmitted along with ancillary information to a central base station for persistent storage of the data in a server. Such stored data is thus available on past and current positions of the mobile object for use by various computer applications to derive information about the object's movements.
