摘要： A method and apparatus for determining time-of-day in a mobile receiver is described. In one example, expected pseudoranges to a plurality of satellites are obtained. The expected pseudoranges are based on an initial position of the mobile receiver and an initial time-of-day. Expected line-of-sight data to said plurality of satellites is also obtained. Pseudoranges from said mobile receiver to said plurality of satellites are measured. Update data for the initial time-of-day is computed using a mathematical model relating the pseudoranges, the expected pseudoranges, and the expected line-of-sight data. The expected pseudoranges and the expected line-of-sight data may be obtained from acquisition assistance data transmitted to the mobile receiver by a server. Alternatively, the expected pseudoranges may be obtained from acquisition assistance data, and the expected line-of-sight data may be computed by the mobile receiver using stored satellite trajectory data, such as almanac data.

摘要： A method and apparatus for locating a remote unit (or node) is provided herein. During operation, location-finding equipment (106) will determine a gross location of non-located nodes (104) by determining distances of the nodes (104) to reference nodes (105). Additionally an error estimate in the location for each node is determined. A first subset of nodes having relatively lower error estimates are “promoted” to reference nodes, and a second subset of nodes having higher error estimates are again located based on a distance to the newly-promoted reference nodes.

摘要： The locations of pseudolites and the location of a stationary reference station are previously known by a user processing unit, and codes and carrier phase of signals transmitted from the pseudolites are measured by the stationary reference station, a moving reference station and a rover receiver. Data of the codes and the carrier phase measured by the stationary reference station, the moving reference station and the rover receiver are transmitted to the user processing unit using a data link. The user processing unit determines a baseline between the stationary reference station and the moving reference station, and a baseline between the moving reference station and the rover receiver. The two baselines and the previously known location of the stationary reference station are employed to determine the position of the rover receiver.

摘要： A method and an apparatus using a low Earth orbiting (LEO) satellite signal to augment the Global Positioning System (GPS) for finding a location vector between a GPS user receiver and a GPS reference receiver. The GPS user receiver computes a LEO user-reference carrier phase difference and a GPS user-reference carrier phase difference for the LEO satellite signal and a GPS satellite signal, respectively, received simultaneously at the GPS user receiver and the GPS reference receiver. Carrier phase double differences are computed from a difference between the GPS user-reference carrier phases from two GPS satellites and either the LEO user-reference carrier phases from two LEO satellites or the GPS user-reference carrier phase from one GPS satellite and the LEO user-reference carrier phase from one LEO satellite. The location vector is computed from a difference between the double differences for two satellite geometries. The GPS reference receiver communicates the reference carrier phase data to the GPS user receiver through the LEO satellite. An ionospheric delay model is determined by tracking the LEO satellite signal as the LEO satellite traverses the sky. An optional calibrator corrects for measurement delay in determining the carrier phases in the GPS user receiver and the GPS reference receiver.
