Abstract: Systems and methods are disclosed herein to use a vehicle back-up camera as a cost-effective dead-reckoning sensor in satellite-based vehicle navigation systems. Since the back-up camera may already use a display of the navigation system for display, the data from the back-up camera may be easily obtained and integrated into the navigation system. The data from the camera is received by a navigation receiver wirelessly or through a wired connection. The image is processed to determine the speed, heading, turn-rate of the vehicle to aid the satellite-based navigation system if the satellite signals are inadequate. Thus, enhanced vehicle navigation- performance can be obtained without adding new sensors and/or connecting to a vehicle data bus.

Abstract: The present invention is related to location positioning systems, and more particularly, to a method and apparatus for using satellite state information from two or more different satellite systems in navigation processing. According to one aspect, it makes use of GPS extended ephemeris functionality to produce satellite state vector estimates for GLONASS satellites. These satellite state vector estimates can be used alone or in combination with GPS satellite vectors to provide updates to the receiver's navigation processing. According to further aspects, the GLONASS satellite position and trajectory information is extrapolated with a GPS gravity model rather than the GLONASS model, thereby allowing it to be extrapolated more accurately and for longer periods of time than the GLONASS model allows.

Abstract: Systems and methods are disclosed herein for using a switched mode TCXO or VC-TCXO in a satellite navigation receiver where the switched mode TCXO or VC-TCXO may operate either in an active compensation mode to compensate for temperature induced frequency error or in a second fixed compensation mode where the TCXO or VC-TCXO is not compensated for temperature. The switched mode TCXO or VC-TCXO is operated in the active compensation mode when satellite acquisition performance may be improved from a reduction in the range of oscillator frequency error. The switched mode TCXO or VC-TCXO may be switched to operate in the fixed compensation mode when satellite tracking performance is sensitive to discontinuities in the phase, frequency, and/or frequency rate of the oscillator clock when temperature compensation is applied.

Abstract: Systems and methods are disclosed herein for using a switched mode TCXO or VC-TCXO in a coherent receiver application where the switched mode TCXO or VC-TCXO may operate either in an active compensation mode to compensate for temperature induced frequency error or in a second fixed compensation mode where the TCXO or VC-TCXO is not compensated for temperature. The switched mode TCXO or VC-TCXO is operated in the active compensation mode when receiver performance may be improved from a reduction in the range of oscillator frequency error. The switched mode TCXO or VC-TCXO may be switched to operate in the fixed compensation mode when receiver performance is sensitive to discontinuities in the phase, frequency, and/or frequency rate of the oscillator clock when temperature compensation is applied. In addition, the switched mode VC-TCXO may operate in a transparent mode to allow change to the oscillator or a latched mode to prevent change to the oscillator.
