20110199260 | METHOD AND SYSTEM FOR DETERMINING A LOCATION OF A CELLULAR BASE STATION UTILIZING MOBILE GNSS VELOCITY AND CORRESPONDING CELLULAR DOPPLER - A GNSS enabled mobile device concurrently receives GNSS signals from GNSS satellites and transmissions from a cellular base station. GNSS-based velocities and GNSS locations are determined for the GNSS enabled mobile device utilizing the received GNSS signals. A cellular Doppler is measured on the cellular base station. A location of the cellular base station is determined based on the determined GNSS-based velocity and corresponding cellular Doppler measurements. The cellular base station may be located by the GNSS enabled mobile device and/or by a remote location server. In this regard, the remote location server may determine the location for the cellular base station utilizing GNSS velocities and corresponding cellular Doppler measurements received from plural GNSS enabled mobile devices in a coverage area of the cellular base station. The determined location of the cellular base station is used to refine GNSS locations of the plurality of GNSS enabled mobile devices when needed. | 08-18-2011 |

20130076564 | METHOD AND APPARATUS OF GNSS RECEIVER HEADING DETERMINATION - The present invention relates to processing information generated by GNSS receivers received signals such as GPS, GLONASS, etc. GNSS receivers can determine their position in space. The receivers are capable of determining both coordinates and velocity of their spatial movement. When a receiver is used in any machine control systems, velocity vector heading (in other words, velocity vector orientation) should be determined along with velocity vector's absolute value. Angle, determining velocity vector orientation, is calculated based on velocity vector projections which are computed in navigation receivers. The accuracy of velocity vector orientation calculated based on velocity vector projections strongly enough depends on velocity vector's absolute value. To enhance the accuracy, a method of smoothing primary estimates of velocity vector orientation angles using a modified Kalman filter has been proposed. The bandwidth of this filter is varied depending on current estimates of velocity vector's absolute value which were calculated based on the same velocity vector projections. | 03-28-2013 |

20140145876 | MACHINE NAVIGATION SYSTEM UTILIZING SCALE FACTOR ADJUSTMENT - A machine navigation system and method for estimating velocity of a machine is disclosed. The method may include receiving, from an odometer, a first signal indicative of a distance traveled by the machine and calculating a scale factor to compensate for an error associated with the first signal. The method may further include determining whether a second signal indicative of a location of the machine is received by the machine and selectively adjusting the scale factor using machine parameters to generate an adjusted scale factor, where selectively adjusting may be performed based on whether the second signal is received by the machine. The method may further include estimating the velocity of the machine based on the first signal and the adjusted scale factor. | 05-29-2014 |
