The Supplementary Measurement Being Of A Radio-wave Signal Type (ipc) Patents (Class 342/357.29)
  • Patent number: 11022694
    Abstract: Methods of checking the integrity of the estimation of the position of a mobile carrier are provided, the position being established by a satellite-based positioning measurement system, the estimation being obtained by the so-called “real time kinematic” procedures. The method verifies that the carrier phase measurement is consistent with the code pseudo-distance measurement. The method comprises a step of calculating the velocity of the carrier, at each observation instant, a step of verifying that at each of the observation instants, the short-term evolution of the carrier phase of the signals received on each of the satellite sight axes is consistent with the calculated velocity and a step of verifying that at each of the observation instants, the filtered position obtained on the basis of the long-term filtered measurements of pseudo-distance through the carrier phase is dependable.

  • Patent number: 10533862
    Abstract: A transport service system identifies a map matched trajectory for a transport vehicle based on planned route information and location data associated with a trip. The system receives planned route information and location data for a transport vehicle. For each location data point, the transport service system identifies a set of candidate road segments. Sequential pairs of candidate road segments represent transitions. The system uses a map of the corresponding area to calculate a transition probability, the likelihood of traversing from the first candidate road segment to the second candidate road segment. The system identifies transitions that correspond to the planned route and adjusts the transition probabilities based on the identified planned route transitions. Based on the adjusted probabilities, the transport service system determines a most-likely traversed path for the transport vehicle.

  • Patent number: 10460420
    Abstract: Embodiments relate to converting spatial features to a map projection. Initially, a map request that specifies the map projection for a geographic area is obtained. A spatial feature is identified for projecting into the map projection. Until a bisect threshold is satisfied for each line segment in the spatial feature, a bisect is determined for each of the line segments; each line segment is projected into the map projection; and if the bisect threshold is not satisfied for a line segment, the line segment is divided into subsegments, where the bisect threshold specifies an error distance for the line segment after projection. The modified spatial feature is projected into the map projection to obtain a projected spatial feature, and a polar coordinate system that corresponds to the map projection is used to render the projected spatial feature in a spatial map.

  • Patent number: 10324194
    Abstract: A Global Navigation Satellite System receiver for position determination receives from a multitude of satellites a respective GNSS code signal, which are correlated with a reference code signal to obtain an autocorrelation function. A multitude of function values of the autocorrelation function at different discrete chip spacings (chosen asymmetrically with respect to a prompt chip spacing) are analyzed and used in obtaining a test metric. Using the test metric, a decision is made whether the received GNSS code signal is suitable or unsuitable (thereafter excluded) for a position determination due to multipath signal components. A bias removal is performed taking into account corresponding function values of an autocorrelation function that would result from a received GNSS code signal of the satellite unaffected by multipath signal components. This provides a simple method for operating a GNSS receiver minimizing errors in position determination caused by multipath signal components.

  • Patent number: 10137863
    Abstract: A system, configured to mount on an ownship vehicle, includes a transceiver configured to receive positioning signals and receive surveillance signals including surveillance data from a second vehicle and processing circuitry configured to determine a location of the ownship vehicle based on the positioning signals received by the transceiver and determine expected characteristics of the surveillance signals based on the surveillance data. The processing circuitry is further configured to compare the expected characteristics and actual characteristics of the surveillance signals received from the second vehicle and determine that the surveillance signals include a discrepancy indicative of false positioning signals in response to comparing the expected characteristics and the actual characteristics. The processing circuitry is configured to output an alert signal indicating the false positioning signals in response to determining that the surveillance signals include a discrepancy.

  • Patent number: 10051423
    Abstract: Embodiments herein relate to using a convolutional neural network (CNN) for time-of-flight estimation in a wireless communication system. A wireless device may receive, from a remote device, wireless communications including a first transmission time value associated with the transmission of the wireless communications. The wireless device may perform a coarse time-of-arrival (TOA) estimation on the wireless communications received from the remote device. The coarse TOA estimation may be used to generate an estimated impulse response, which may be input to a CNN associated with the wireless device to calculate a line-of-sight estimate. The wireless device may determine a range between the wireless device and the remote device based on the transmission time value and the line-of-sight estimate.

  • Patent number: 10015762
    Abstract: Systems and associated methods for reducing Doppler shifts in the broadband signals between Unmanned Aerial Vehicles (UAVs) and ground stations are disclosed herein. In one embodiment, a method for reducing the Doppler shift of wireless signals includes estimating a velocity of the UAV based on a Global Positioning System (GPS) or an Inertial Measurement Unit (IMU) of the UAV and calculating the Doppler shift of an upload (UL) wireless signal based on the velocity of the UAV. The method further includes predistorting a frequency of the UL wireless signal at the ground station to reduce the Doppler shift at a UAV receiver (RX) and transmitting the UL wireless signal from a ground station transmitter (TX) to the UAV RX. In some embodiments, calculating the Doppler shift of the UL wireless signal is performed at the ground station.

  • Patent number: 9967799
    Abstract: Customized communication routing and regulation thereof are provided. The routing of an incoming communication to a device, wireless or wireline, is based on a routing preference and a presence condition of a mobile device in a home or visited wireless environment served by a confined-coverage access point (AP). The routing preference can be configured for a device that operates in the home or visited wireless environment. The confined-coverage AP can be owned or leased by a subscriber associated with the incoming call or by a third party. Provisioning of routing of incoming call based on a third-party confined-coverage AP can be event-based. Add-on services can be provisioned and configured; screening of incoming call(s) based on screening rule(s) specific to a confined-coverage AP is provided. Customized communication routing to equipment that operates in a confined-coverage area served by a third-party confined-coverage AP can be canceled.

  • Patent number: 9949083
    Abstract: A system and method for improved location tracking of a target device based on location estimates for multiple types of location technologies/sensor types. A received signal strength location estimate of a target device based on wireless transmissions made by the target device received at a plurality of receiver devices at known locations in a location region. A first search area for the target device is derived based on the received signal strength location estimate. An ultrasound based area in which the target device is estimated to be is derived based on reception by the target device of a particular ultrasound beacon in the location region. An intersection of the first search area and the ultrasound based area is computed to produce a second search area. A location estimate of the target device in the second search area is computed based at least on the received signal strength location estimate.
