  • Patent number: 9445447
    Abstract: A system and a method for establishing short range wireless communication between two vehicle modules. The system determines the availability of a first vehicle module and a second vehicle module to establish a short range wireless communication connection. The determination may be based upon whether the first vehicle module is storing pairing data. The system validates the pairing data at the second vehicle module using a wired connection. If the pairing data is validated, the first and second vehicle modules may establish a wireless connection using at least a portion of the pairing data. When the wireless connection ends, the system may re-determine the availability and revalidate any pairing data via the wired connection before establishing a wireless connection.

  • Publication number: 20160025859
    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.
