    Abstract: A method is described for estimating the coordinated universal time (UTC). The method involves receiving, by a satellite navigation receiver, signals broadcast by a global navigation satellite service (GNSS) satellite. The signals encode a first time of week (TOW) value. The method also involves estimating a first week number (WN) value and a first relationship between the UCT and a reference time of an onboard clock of the GNSS satellite (OFFSET) from time parameter values stored at a local memory. The method determines a first estimate of the UTC from the first TOW value, the first WN value, and the first OFFSET.

  • Patent number: 9638783
    Abstract: Methods, systems, and devices are described for peer-to-peer or device-to-device location services. Mobile devices with a known location (referred to as landmarks) may broadcast their location information and/or a reference signal for other mobile devices (referred to as targets). Landmarks may determine their location through GPS or other location determining means. Targets may have limited or no connection to location determining services, and they may use broadcast information from landmarks, without a request, to determine the targets' location. The targets may determine absolute and/or relative locations. Once a target device determines its location it may assume a role of a landmark to provide broadcast location information to other devices.
