  • Patent number: 9912036
    Abstract: An approach for determining remote terminal antenna alignment in a satellite communications system is provided. A point in time for an expected conjunction of an a remote terminal antenna, a satellite in communication with the remote terminal and the Sun is determined based on predetermined positional data. An interference level imposed by the Sun on communication signals between the antenna and the satellite is measured at a number of respective points in time. A one of the points in time is determined when the interference is at a peak level. Then information regarding alignment of the antenna with respect to the satellite is determined, wherein the determination of the antenna alignment information is based on a comparison between the one point in time of the peak interference level and the expected point in time of the conjunction of the antenna, the satellite and the Sun.

  • Patent number: 9891325
    Abstract: A global navigation system includes a first navigation receiver located in a rover and a second navigation receiver located in a base station. Single differences of measurements of satellite signals received at the two receivers are calculated and compared to single differences derived from an observation model. Anomalous measurements are detected and removed prior to performing computations for determining the output position of the rover and resolving integer ambiguities. Detection criteria are based on the residuals between the calculated and the derived single differences. For resolving integer ambiguities, computations based on Cholesky information Kalman filters and Householder transformations are advantageously applied. Changes in the state of the satellite constellation from one epoch to another are included in the computations.
