Compact Optical Inertial Reference Unit (COIRU)

ATA proposes to develop a Compact Optical Inertial Reference Unit (COIRU) to address the requirements of the Optical Inertial Reference Unit (OIRU) for Navy Tactical Airborne High Energy Laser (HEL) Application solicitation. The COIRU proposes the following innovative technical approach to address the customer challenges: Single center mounted spinning mass gyroscope as the inertial stabilization sensor Gyroscope rotor caging to the gyroscope case using a stable platform actuators controller design Swappable fiber-coupled laser source that does not degrade optical alignment Gyroscope signals digitized in the base of the COIRU mechanism A simple digital and power interface for operation ATA"s proposed COIRU addresses all of the requirements of the solicitation topic and offers improved optical IRU performance in an incredibly small package (2"x2"x2") at a very low price ($120,000/unit). ATA anticipates a successful Phase I and Phase II effort will provide a very small optical IRU that can operate in a wide variety of military environments including airborne, ground, and sea-based. Because of the COIRU"s small size and performance capability, it can support a wide variety of applications such as high-energy lasers, target designation, laser radar and laser countermeasure systems.
