Abstract: A method, GNSS simulator, and non-transitory computer readable medium for providing a simulated global navigation satellite system (GNSS) signal. The method includes receiving, by a GNSS simulator, a precision timing signal and one or more items of ephemeris data from a GNSS receiver based on a decoded GNSS signal received by the GNSS receiver. The precision timing signal and the one or more items of GNSS ephemeris data are received in a digital format over a communication network. A simulated GNSS signal is generated, by the GNSS simulator, based on the received precision timing signal and one or more items of ephemeris data. The simulated GNSS signal is transmitted, by the GNSS simulator, over a coverage area. A GNSS system for providing a simulated GNSS signal is also disclosed.

Abstract: A reference management apparatus includes a reference signal housing, a fixed length propagation device, an oscillator device, and a reference management computing device. The reference signal housing having a propagation signal output and a propagation signal input. The fixed length propagation device is coupled between the propagation signal output and the propagation signal input. The reference signal management computing device is coupled to the oscillator device and the propagation signal input.

Abstract: A method, non-transitory computer readable medium and timing computing device for subnanosecond time synchronization. A difference between synchronized measurements of one of a plurality of satellite signals from a reference receiver and another receiver for each of N values within a cycle is determined. A clock bias error is calculated for each of the N values. The calculated clock bias errors are stored in a vector over time for each of the N values, with one of the vectors for each of the N values. A trajectory of the vectors over time is determined. The one of the vectors with a best convergence over time is selected. A timing signal is adjusted based on the N value for the selected one of the vectors with the best convergence over time.

Abstract: A method, non-transitory computer readable medium, and apparatus that determines a GPS location includes obtaining assisted GPS data of locations of a plurality of GPS satellites, current time, and initial location data of the receiver computing device. A GPS signal from one or more of the plurality of GPS satellites within a frequency range and time range is acquired based on the obtained assisted GPS data, current time, and initial location data of the receiver computing device. The one or more acquired GPS signals are integrated over a frame period of two or more seconds. A GPS location for the receiver computing device is determined based on the one or more integrated GPS signals.

Abstract: A method, computer readable medium, and system for managing a mobile communication network includes identifying one or more mobile communication devices within a region. One of the one or more identified mobile communication devices which have been dynamically formed into one or more clusters having a tree structure and are at least partially meshed together is elected as a cluster head in each of one or more clusters based on one or more parameters.

Abstract: A method, computer readable medium, and system for providing a mobile communication network includes dynamically forming a plurality of mobile communication devices into one or more clusters based on one or more parameters, each of the one or more clusters having a tree structure. Each of the one or more clusters are at least partially meshed together. At least one virtual identifier is dynamically assigned to each of the plurality of mobile communication devices based on the tree structure of each of the one or more clusters. The virtual identifier provides address information for routing communications between two or more of the plurality of mobile communication devices.

Abstract: A system is described for providing one or more remote paging receivers with accurate time of day information utilizing a paging provider which encodes page messages into RF signals corresponding to baseband signals for transmission via a paging channel to the receivers. The system includes the receivers and a controller. The controller sends a first page message, which defines an on-time point, to the paging provider for transmission via the paging channel to the receivers, and then sends a second page message to the paging provider for transmission via the paging channel to the receivers. Further, the controller detects the transmission of the first page message in the paging channel and determines a time of day when the on-time point of the first page message was transmitted by the paging provider in the paging channel. The second page message sent by the controller comprises data defining this determined time of day.
