Tracking of Occluded Navigation Satellite Signals |
| 摘要 |
A navigation system for navigating a vehicle includes a position module for determining a current position of the vehicle by tracking at least one satellite signal, and an estimation module for identifying, upon an interruption of the tracking the satellite signal, an object blocking the satellite signal. The estimation module is also configured for determining, using a property of the object, a next position of the vehicle at a distance from the current position at which the navigation system reacquires the satellite signal, and the navigation system also includes an acquisition module for determining a phase of the satellite signal at the next position and for initializing, upon reacquiring the satellite signal, the tracking of the satellite signal using the phase. |

1. A navigation system for navigating a vehicle, comprising:
a position module for determining a current position of the vehicle by tracking at least one satellite signal; an estimation module for identifying, upon an interruption of the tracking the satellite signal, an object blocking the satellite signal and for determining, using a property of the object, a next position of the vehicle at a distance from the current position at which the navigation system reacquires the satellite signal; and an acquisition module for determining a phase of the satellite signal at the next position and for initializing, upon reacquiring the satellite signal, the tracking of the satellite signal using the phase. |
