Navigation with satellite communications |
September 8, 2009 |
| A Low Earth Orbiting (LEO) satellite is used for broadcasting differential navigation corrections. Using LEO satellites, the "footprint" of the beam is much smaller than for geosynchronous satellites. Datalink bandwidth requirements are reduced to sufficiently cover an entire footprint a |

Satellite navigation system using multiple antennas |
April 11, 2006 |
| A satellite navigation system using multiple antennas for providing the position of multiple fiduciary points on an object even when fewer than four satellites are visible to some or all the antennas. Satellite signals from the multiple antennas are fed into at least one receiver. Th |

Rapid adjustment of trajectories for land vehicles |
November 4, 2003 |
| A method for adjusting a desired trajectory of an automatically guided vehicle guidance system to match a physical constraint such as an obstacle or boundary. The method works around obstacles and boundaries as they occur, consistent with the original trajectory. The method is independen |
