  • Method, apparatus and system for GPS time synchronization using cellular signal bursts
    Patent number: 9341716
    Abstract: A system, apparatus and corresponding method by which to synchronize to a time reference a main module of a device—a main module such as global positioning system (GPS) receiver—using a cellular communication signal received by a cellular module also included in the device. To synchronize the main module to the reference time, the invention provides a method including the steps of: having the cellular module respond to the cellular communication signal by providing to a clock module of the main module a trigger pulse derived from the data component of the cellular communication signal, and also by providing to the main module information relating the trigger pulse to a universal time. The main module is then able to resolve a value for time based on the information relating the trigger pulse to a universal time and the trigger pulse.

  • Extended fingerprint generation
    Patent number: 9304970
    Abstract: A system for creating a representation of a location based on information sensed at the location. For example, apparatuses may comprise various sensors that sense apparatus-related information (e.g., motion, direction, etc.) while also visual, signal, field, etc. information pertaining to a location. Apparatuses may store sensed information about the apparatus while at a particular location, and about the particular location itself, in a mapping database, which may then associate the various types of sensed information with information already stored in the database in order to create a representation of the location.

  • Supporting an assisted satellite based positioning
    Patent number: 8878723
    Abstract: For supporting a satellite based positioning of a mobile arrangement (30, 40) with assistance data, a communication network converts parameters of a dedicated orbit model describing a movement of a satellite (50, 60), which dedicated orbit model is defined for a particular satellite based positioning system, into parameters of a common orbit model describing a movement of a satellite (50, 60). Alternatively or in addition, the network replaces a reference value that is based on a satellite based positioning system time in available parameters of an orbit model by a reference value that is based on a communication system time. After the parameter conversion and/or the reference value replacement, the parameters are provided as a part of assistance data for the satellite based positioning.
