ABSTRACT:
An inertial navigation system is provided. The system includes a gas supported sensor block that is adapted to rotate in three dimensions in a near frictionless environment, a plurality of jet plates adapted to receive two or more pairs of opposing pneumatic nozzles and a plurality of electronically controlled pneumatic valves that provides and controls gas to the opposing pair of pneumatic nozzles. Each pair of opposing pneumatic nozzles is directed at an exterior surface of the sensor block and uses gas flow to move and hold the sensor block in any rotational location without physically touching the sensor block.
