摘要： A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.

摘要： A navigational apparatus and method for augmenting a GNSS signal to the GPS simulator with alternative position, navigation, or timing (PNT) data, wherein the GPS simulator encodes an RF-simulated GPS signal based on the alternative PNT data when the GNSS signal is not available or is denied. The alternative PNT data may be provided by one or more of an Inertial Measurement Unit, Inertial Navigation System (IMU/INS) module and oscillator coupled to the GPS simulator.

摘要： An antenna system includes a right-hand circularly polarized antenna for receiving Global Navigation Satellite System (GNSS) signals and located on a receiver housing; a vertical semitransparent screen for providing an Down/Up ratio DU 9 0 = DU ( θ e = 9 0 ∘ ) = F ( - 9 0 ∘ ) F ( 9 0 ∘ ) of −13 dB or better for at least some GNSS frequencies; the semitransparent screen being connected to a ground plane of the antenna; the ground plane being connected to a conductive receiver housing; the semitransparent screen further comprising a horizontal slot to which sets of lumped impedance elements are connected. Each set includes several lumped elements; where the lumped elements are capacitors and/or inductors and/or resistors; where the lumped elements in each set are connected in parallel or series; and the semitransparent screen including at least 4 segments arranged symmetrically around the center of the antenna and connected to each other.

摘要： A method of receiving and decoding non-legacy GNSS signals and re-transmitting these in real-time as legacy GPS (L1-C/A) signals decoding into standard PVT/PNT information then re-encoding using a real-time GPS simulator as legacy GPS code signals, and outputting as a legacy GPS antenna signal. A navigational apparatus for performing the method may further include an Inertial Measurement Unit, Inertial Navigation System (IMU/INS) module and oscillator coupled to the GPS simulator for providing an inertial location signal supplementing the GNSS signal to the GPS simulator, wherein the GPS simulator encodes the RF simulated GPS signal based at least in part on the inertial location signal for a period when at least one of the GNSS signal or the PVT/PNT signal is not available.

摘要： This disclosure describes methods, systems and machine readable media that can provide position solutions using, for example, pattern matching with GNSS signals in urban canyons. In one method, based upon an approximate location in an urban canyon and a set of 3D data about building structures in the urban canyon, an expected signal reception data can be generated for both line of sight and non-line of sight GNSS signals from GNSS satellites, or other sources of GNSS signals, at each point in a set of points in a grid (or other model) in the vicinity of the approximate location). This expected signal reception data can be matched to a received set of GNSS signals that have been received by a GNSS receiver, and the result of the matching can produce an adjustment to the approximate location that is used in the position solution of the GNSS receiver.

摘要： First information is obtained from a sensing device at a first time. The first information corresponds to a radio signal received at the device from a candidate location. The device is at a first location at the first time. Second information is obtained from the device at a second time. The second information corresponds to a radio signal received at the device from the candidate location. The device is at a second location at the second time. A system determines that a pattern is in each of the first and second information and determines relationships between the candidate location and the device at each first and second location. The system obtains inverses of the relationships and determines estimates of the received radio signals based on the information and inverses. The system measures or estimates energy emitted from the candidate location based on the estimates.

摘要： In one embodiment, the present invention includes a method of receiving and decoding military L2 or L1 P(Y) or M-Code signals and re-transmitting these in real-time as legacy L1-C/A signals. The decoding process of the P(Y) or M-code is done through the programming by the user of secret keys into an embodiment of this invention. These military code signals are then decoded into standard PVT/PNT information which are typically transmitted on an industry standard serial port and format, which are then re-encoded using a real-time GPS simulator sub-system as legacy L1-C/A code signals, and transmitted to the output of the embodiment of this invention as a standard antenna signal. This output signal could be made compatible with any commercial L1-C/A code GPS receiver, and may thus be decoded by the GPS receiver as if the signals had been received directly from the Satellites. In one application of this embodiment of this present invention the legacy GPS receiver does not know the difference and cannot differentiate between signals generated by this embodiment of the present invention versus true GPS satellite signals received by a real GPS antenna. This embodiment of the present invention allows efficient replacement of legacy GPS antennae without having to change any of the system, setup, cabling, or programming of the legacy GPS receiver system. Another embodiment of this present invention may receive Glonass, BeiDou, or Galileo signals, and output legacy GPS signals to allow a glueless retrofit of legacy GPS receivers to Glonass, BeiDou, or Galileo compatibility.

摘要： It is provided a joint receiver and receiving method for navigation signals located at adjacent frequencies. The joint receiving method includes: receiving a first navigation signal and a second navigation signal which are located at adjacent frequencies (S1); and calculating a frequency estimation of a virtual wideband navigation signal constructed based on the first navigation signal and the second navigation signal (S2), wherein the virtual wideband navigation signal is an asymmetric BOC-like navigation signal having a virtual carrier and a virtual sub-carrier. With the joint receiver and joint receiving method, not only power gain but also bandwidth gain can be obtained, and the ranging precision can be significantly improved.
