    摘要: A global navigation satellite system (GNSS) receiver is disclosed. In embodiments, the GNSS receiver includes a tracking engine running on a primary controller, the tracking engine configured to receive a plurality of signals from a plurality of satellites. The GNSS receiver further includes a space-time adaptive correlator (STAC) engine running on an application-specific controller. In embodiments, the STAC engine is configured to: receive initial position data and an initial receiver clock estimate from the tracking engine; construct a spatial hypercube based on the received initial position data; receive the plurality of signals from the tracking engine; interpolate signal strengths of the plurality of signals to generate a plurality of signal intensity curves; integrate the plurality of signal intensity curves within the spatial hypercube for the initial receiver clock estimate to generate a signal intensity hypercube plot; and determine a receiver position based on the signal intensity hypercube plot.

    摘要: Radio communications systems use 100 to 200 satellites in random low-earth orbits distributed over a predetermined range of north and south latitudes. The satellites themselves create a radio route between ground stations via radio links between multiple satellites by virtue of onboard global navigation satellite system circuitry for determining the location of the satellite and route creation circuitry for calculating in real time the direction from the satellite's location at a particular instant to a destination ground station. Directional antennas in the satellites transmit routing radio signals to enhance the probability of reception by other satellites. One embodiment facilitates the creation of satellite-to-satellite links by assigning each satellite a unique identifier, storing orbital information defining the locations of all of the orbiting satellites in the system at any particular time, and including in the radio signal the unique identifier associated with the transmitting satellite.

    摘要: Container tracking systems and related methods. A container tracking assembly comprises a processor having a powered-off state and a sleep state, at least one sensor, a radio frequency transceiver, and a power source in electrical communication with the processor, the at least one sensor, and the radio frequency transceiver. Additionally, the container tracking assembly comprises a non-transitory memory having instructions stored thereon, wherein the instructions, when executed by the processor, are operative to acquire, via the radio frequency transceiver, a current location of the container and cause the processor to enter the powered-off state if the current location of the container does not differ from a previously-acquired location of the container by more than a threshold amount. If the current location of the container differs from the previously-acquired location of the container by more than the threshold amount, the processor enters the sleep state for a first period of time.

    摘要: A device for mitigating satellite navigation spoofing includes processing circuitry which detects correlation peaks for PRNs in a satellite navigation signal. The TOAs of subframes of navigation messages associated with each of correlation peaks are recorded and analyzed to determine if they fall within a specified time window. Based on the analysis, the correlation peaks are classified as legitimate or as spoofed. A correct geographic location is computed from the navigation data associated with the legitimate correlation peaks. Corresponding methods for mitigating satellite navigation spoofing may be embodied in a hardware-based GNSS receiver and in a software-based GNSS receiver.

    摘要: The present disclosure relates to the field of shared bicycles, and particularly relates to a heartbeat control system for shared bicycles. The heartbeat control system may include a server configured to divide an area that includes the shared bicycles into a plurality of parking zones based on a virtual map and determine an off-peak period and a peak period of each of the plurality of parking zones, and a lock control device mounted on one of the shared bicycles. The lock control device may include a network module that is periodically actuated by the lock control device. The lock control device may be configured to obtain, based on a parking zone of the shared bicycle, an off-peak period and a peak period corresponding to the parking zone, and extend an actuation frequency during the off-peak period.

    摘要: Disclosed herein are techniques for managing concurrent reception of satellite position signals and transmission of wireless network signals. In some embodiments, a measurement engine is configured to generate measurements based on Global Navigation Satellite System (GNSS) signals received by a GNSS wireless receiver, including a first measurement based on a first GNSS signal. A determination is made as to whether a wireless transmitter is active in a first frequency band when the GNSS wireless receiver receives the first GNSS signal, where the first frequency band is a frequency band of the first GNSS signal. In response to a determination that the wireless transmitter is active in the first frequency band when the GNSS wireless receiver receives the first GNSS signal, a position calculation operation and/or a clock bias calculation operation can be performed using measurements other than the first measurement.
