Abstract:
1. An inertial navigation system, the system comprising: a sensor block; an outer shell having a first half shell and a second half shell; a mid plate; wherein the first half shell and the second half shell of the outer shell mate with the mid plate and substantially surround the sensor block; a plurality of gas pads connected to the outer shell that suspend the sensor block in gas creating a near frictionless environment to allow the sensor block to move to any angular position; a first gas plenum that substantially surrounds the first half shell; a second gas plenum that substantially surrounds the second half shell; and a plurality of gas jets for applying a torque to the sensor block; wherein the first gas plenum and the second gas plenum mate with the mid plate and substantially surrounds the outer shell; wherein each of the plurality of gas pads is adapted to receive pressurized gas; wherein the outer shell and the sensor block are separated by a gap created by the pressurized gas.
