摘要： A system for accurate geospatial location and time transfer using radio transmissions without satellite signals. A position and timing measurement system uses standard uncorrelated radio broadcast signals, each of which transmits on an assigned frequency from a known position defined in latitude and longitude, and each of which transmits a modulated or unmodulated carrier signal. A reference unit at known fixed position receives the said standard broadcast signals in the vicinity, samples the frequencies and content values of their signals and broadcasts the said measured frequency and content data nearly simultaneously with a time mark representing the time of said measurement and further broadcasts its position in latitude and longitude. A mobile unit at an unknown position to be determined receives the said standard broadcast signals in the vicinity and measures the time of arrival of their broadcast, recording the time of said measurement.

摘要： Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described. The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.

摘要： In aspects of environment dead zone determination based on UWB ranging, a system includes ultra-wideband (UWB) radios associated with respective devices in an environment. An automation controller receives UWB ranging data from the UWB radios, and can monitor locations of the respective devices in the environment. The automation controller can detect a loss of coverage by a device connected in the environment, and determine a coverage dead zone within the environment at the location of the loss of coverage by the device based on the UWB ranging data. A computing device can implement the automation controller that receives the UWB ranging data from the UWB radios, and monitors the locations of the respective devices in the environment. The automation controller can detect the loss of coverage by the device, and determine the coverage dead zone within the environment at the location of the loss of coverage by the device.

摘要： According to one aspect of the presently disclosed subject there is provided a system implemented in a mobile carrier for determining a position of the mobile carrier by using a processing and memory circuitry (PMC) and a satellite communications on the move (SOTM) antenna system, being configured to maintain a communications link from a satellite communications (SATCOM) having a spatial position. The system is configured to obtain data indicative of the spatial position of the SATCOM, the estimated altitude of the mobile carrier and the direction of the antenna towards the SATCOM spatial position and to determine the position of the mobile carrier.

摘要： A method for signal evaluation in a locating system that includes multiple radar sensors whose locating ranges overlap one another. The method includes evaluating the signal of a first of the radar sensors and identifying distance cells that are not empty, for at least one of these distance cells: selecting a second of the radar sensors and determining a distance range in which the objects situated in the distance cell would have to be situated from the viewpoint of the second radar sensor, and classifying the object configuration in the distance range, based on the signal of the second radar sensor.
