First Claim
Patent Images
1. A system comprising:
- a first assembly comprising a first global navigation satellite system (GNSS) antenna operatively associated with a first accelerometer set;
a second assembly comprising a second GNSS antenna operatively associated with a second accelerometer set;
a rigid body that is operatively connected to the first assembly and the second assembly, wherein the first and second assemblies are separated by a predefined distance, whereby movement of the rigid body causes both the first and second assemblies to move; and
a processor configured to computer a baseline vector between the first and second assembly and further configured to compute rotational information using data from the first and second accelerometer sets.

Abstract
A system and method for providing location information using a long baseline accelerometer/GNSS system. A first set of accelerometers is operatively associated with the first GNSS antenna while a second set of accelerometers is operatively associated with a second (or more) GNSS antenna. The multiple assemblies are separated by predefined distances and held rigid to each other. Accelerometer data is combined with the GNSS data to provide improved navigation and location information.
