  • Patent number: 10866323
    Abstract: The present invention discloses a test method and arrangement for testing GNSS signals within a test chamber. The test chamber inner walls are supplied with transmitting antennas supplying simulated satellite signals, originating from a signal generator. Dynamic satellite movements are simulated by interpolating several transmitted signals in order to create a single true satellite transmission signal. All visible satellites are taken into account in order to create simulated GPS signals across the whole virtual sky. Phantom objects may be used near the device under test and the phantom object may be moved or rotated in preset patterns within the test chamber. Radio channel information can be modelled according to several different real-life environments, and also reflections from any surfaces and different multipath options are taken into account in the modeling, and also in the transmission antenna angles towards the device under test.

  • Patent number: 10866325
    Abstract: Apparatus and methods permit the use of a microelectromechanical systems (MEMS) oscillator in a satellite positioning system receiver, such as a Global Positioning System (GPS) receiver. Techniques to ameliorate jitter or phase noise disadvantages associated with MEMS oscillators are disclosed. For example, a receiver can use one or more of the following techniques: (a) use another source of information to retrieve ephemeris information, (2) perform advanced tight coupling, and/or (3) use a phase-locked loop to clean up the jitter or phase noise of the MEMS oscillator. With respect to advanced tight coupling, an advanced tight coupling processor can include nonlinear discriminators which transform I and Q data into linear residual measurements corrupted by unbiased, additive, and white noise. It also includes an amplitude estimator configured to operate in rapidly changing, high power noise; a measurement noise variance estimator; and a linear residual smoothing filter for input to the navigation filter.

    Abstract: A location system acquires a first set of Global Navigation Satellite System (GNSS) satellites from a first set of raw GNSS signal data received by a GNSS receiver, using all of the coarse acquisition (C/A) codes for the system of GNSS satellites, to determine a first set of GNSS satellites to use for location processing. At a later time, the location system determines respective sets of GNSS satellites as subsets of successive sets of previously determined sets of GNSS satellites. When the number of identified satellites is less than a threshold, the location system again acquires a set of GNSS satellites from raw data using all of the C/A codes for the system of GNSS satellites.
