  • Patent number: 10732295
    Abstract: The positioning receiver according to the invention comprises means for storing configuration information and information on its reception conditions, which is processed in order to calculate a current and/or predicted precision of the positioning calculation. Advantageously, at least some of this information is integrated into a variation model of a Kalman filter integrated into the receiver. The invention notably allows a more rapid convergence on a reference precision in a mono-frequency operating mode and transitions between a mono-frequency and bi-frequency mode to be smoothed. Advantageously, the precision information is delivered graphically or in numerical form to the user.

  • Patent number: 10694382
    Abstract: A mobile device, which includes a satellite navigation system receiver with embedded confidential seed key for generating Galileo message authentication codes (MACs) for any desired time instant, generates a MAC for a given time instant and transmits the MAC or a derived code as a verification code. A receiving entity authenticates the satellite navigation system receiver by comparing the obtained verification code with an available verification code known to be valid for the given time instant. The satellite navigation system receiver is considered to be an authentic satellite navigation system receiver of a mobile device only, in case the at least one obtained verification code matches the available verification code. Selected further actions are enabled only, if the satellite navigation system receiver is considered an authentic satellite navigation system receiver.

  • Patent number: 10658729
    Abstract: Various arrangements for aligning a satellite antenna is presented. An expected date and an expected time for an expected conjunction of the satellite antenna, a satellite that transmits data to a remote terminal and the sun may be determined using positional data. A signal may be received by the antenna that comprises a data transmission from the satellite and interference from the sun. Based on the received signal, a date and time during which an interference level is at a peak interference level can be determined. An azimuthal or elevational alignment for the satellite antenna to be aligned with the satellite based on the time during which the interference level is at the peak interference level may be determined. An alignment of the satellite antenna may be performed based on the determined azimuthal or elevational alignment.

  • Patent number: 10656240
    Abstract: Determining a signal emitter location involves receiving a signal of interest (SOI) at detection devices, generating a time stamp corresponding to the arrival of the SOI at each detection device, and communicating digital data samples and the time stamp to a time-difference of arrival (TDOA) computer system. The TDOA computer system determines a TDOA of the SOI at the detection devices relative to an arrival time at a first one of the detection devices having an earliest time stamp. It determines a first solution to identify the emitter location in accordance with a first TDOA solution method. It evaluates the reliability of the first solution and selectively uses a second solution if the first solution is insufficiently reliable.

  • Patent number: 10642560
    Abstract: A tracking system is described having at least two mobile transmitter/receivers (“transceivers”) which sense and respond to at least one tracking transceiver. The signals sent to and received from the mobile transceivers are analyzed to get a distance (range) that each is from the tracking transceiver. This can be converted into a position relative to the mobile transceivers. If there are enough transceivers, and at least one knows its absolute location, the absolute location of the mobile transceivers may be determined. Existing smartphones, cellphones, WI-FI® wireless standard routers, BLUETOOTH® wireless standard devices, and near-field devices that have on-board processors, can be modified to run executable code to implement the current invention. They may communicate using at least one of the modalities for tracking.

  • Patent number: 10627526
    Abstract: A position is determined using GNSS (Global Navigation Satellite Systems) with an antenna assembly having a number of antennas that are oriented with different direction vectors. Antenna-received signals are supplied to an evaluation assembly, which includes GNSS receivers and an evaluation device. The antenna-received signals are detected with regard to their satellite-related signal-to-noise ratio and, in relation to each satellite, the satellite-specific signal-to-noise ratio measured values that are positively distinguished in their signal-to-noise ratio from other signal-to-noise ratio measured values relating to the same satellite are selected. A satellite-related main direction vector signal is formed from each of the direction vector signals of the antennas. The main direction vector signals are compared with the orientation vector signals that characterize the position of the respective satellites in orbit; in the event of minor deviations a position indication is given.
