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: Se describe un sistema de determinacion de posicion hibrido. Un dispositivo movil puede determinar un numero de pseudoalcance sobre la base de un primer sistema de determinacion de posicion, como un sistema de posicionamiento global. En casos donde la posicion del dispositivo movil es indeterminada debido a un numero insuficiente de pseudoalcances de satelite, el dispositivo movil recibe informacion de posicion incompleta de otros dispositivos. Los otros dispositivos incluye un segundo dispositivo movil. El primer dispositivo movil puede determinar su posicion sobre la base de un numero indeterminado de pseudoalcances de satelite determinando pseudo alcances para otros dispositivos moviles. En otras modalidades, el numero de pseudo alcances de satelite puede ser insuficiente para generar una determinacion de posicion absoluta de un solo dispositivo movil. En esta condicion indeterminada, los dispositivos moviles pueden determinar una ubicacion comun del grupo o pueden determinar un posicionamiento relativo de los miembros del grupo.

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 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.
