Abstract: A hybrid position determination system is disclosed. A mobile device may determine a number of pseudo ranges based on a first position determination system, such as a Global Positioning System. In instances where the position of the mobile device is underdetermined because of an insufficient number of satellite pseudo ranges, the mobile device shares position information with other devices. The other devices may include other mobile devices. A first mobile device may determine its position based on an underdetermined number of satellite pseudo ranges by determining pseudo ranges to other mobile devices. In other embodiments, the number of satellite pseudo ranges may be insufficient to generate an absolute position determination of a single mobile device. In this underdetermined condition, mobile devices may determine a common location of the group or may determine a relative positioning of members of the group.

Abstract: Signal acquisition assistance data is obtained for receiving devices such as wireless position assisted location devices (208, 210) seeking signals from any source (B1-B10), such as satellite vehicles and base stations. The data may be obtained from previously acquired data, based upon evaluation of changes in parameters such as time and location that may jeopardize validity . In some cases the data may be adjusted for the changes in parameters. Refine d data may be calculated by a receiver using partial measurements of signal sets, particularly if the acquisition assistance data provided by a remote entity includes more distinct parameters than have typically been provided. New data need not be obtained until the validity of previous data expires du e to limitations upon temporal extrapolation using Doppler coefficients, unles s mobile station movement that cannot be compensated is detected, and jeopardizes validity of the previous data.

A mobile device may determine a number of pseudo ranges based on a first position determination system, such as a Global Positioning System. In instances where the position of the mobile device is underdetermined because of an insufficient number of satellite pseudo ranges, the mobile device receives shard position informati on from other devices. The other devices include a second mobile device. The first mobile device may determine its position based on an underdetermined number of satellite pseudo ranges by determining pseudo ranges to other mobi le devices. In other embodiments, the number of satellite pseudo ranges may be insufficient to generate an absolute position determination of a single mobi le device. In this underdetermined condition, mobile devices may determine a common location of the group or may determine a relative positioning of members of the group.

Abstract: Metodos y aparatos para obtener un grupo ordenado de satelites del sistema de posicionamiento satelital (SPS), en vista de un receptor SPS movil, a traves de la comunicacion de una o dos direcciones con el receptor SPS movil. El receptor SPS movil recibe, en una modalidad, un grupo ordenado de satelites SPS procedentes de un sitio de transmision celular. El grupo ordenado de satelites son aquellos en vista del receptor SPS movil en un momento determinado; de modo que el receptor SPS movil puede buscar los satelites SPS de acuerdo con un orden del grupo ordenado de satelites SPS. El orden del grupo ordenado puede obtenerse a traves de varios metodos, de los cuales uno es minimizando la dilucion geometrica del satelite de precision (GDOP); datos altos pueden ser incluidos en la transmision.

Abstract: Methods and apparatuses for removing the effects of cross-correlation on a satellite positioning system's calculation of position are disclosed. The method includes receiving the SPS signals from in view SPS satellites and determining whether a first measurement, corresponding to a first SPS satellite which has been indicated to be a healthy satellite, is to be removed from a set of measurements to be used to solve for a position of a mobile SPS receiver. Determining includes testing the first measurement for a cross-correlation resulting from signals from the first SPS satellite and signals from a second SPS satellite, where the first measurement is derived from the SPS signals. In one embodiment, the signals from the first SPS satellite may be weaker than the signals from the second SPS satellite, which has been indicated to be an unhealthy satellite.
