    Abstract: Raw measurements for a plurality of GNSS satellites are pruned based on signal to noise ratio (SNR) and elevation; with remaining unpruned raw measurements sorted by SNR into a sorted list of raw measurements. A first dilution of precision (DOP) based selecting process is performed to select an initial candidate list of raw measurements. The first DOP selecting process begins by using at least those of said pruned list of raw measurements which exceed an SNR quality threshold. The initial candidate list of raw measurements is sorted by elevation angle. A second DOP selecting process is performed to select a final candidate list of raw measurements. The second DOP selecting process begins by using at least those of the sorted initial candidate list which an elevation quality threshold. The final candidate list is used in position computation for a present epoch.

    Abstract: An apparatus corrects a position coordinate measured by a GPS receiver. Road data representing a position coordinate of a constructed road is included. Locus data representing a plurality of position coordinates of the GPS receiver during a past specified period is generated based on a position coordinate acquired. A road section traveled by the GPS receiver during the past specified period is estimated based on road data stored and a position coordinate acquired. A bias error of a position coordinate measured by the GPS receiver is estimated based on position coordinates at a plurality of points in a road section estimated and position coordinates at a plurality of points represented by the locus data. A position coordinate measured by the GPS receiver is corrected based on a bias error estimated and outputted.

    Abstract: 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.
