Ground Tracking Orientation Sensor (GTOS)

ISC proposes development of a laser-based sensor for applications in measuring position and orientation of soldier weapons systems. The proposed sensor concept is designed to continuously track movement of the weapon in six degree of freedom. A preliminary analysis shows that a miniature sensor (including battery) can be packaged in a volume of 1 inch wide by inch high by 4 inches long. Modeling of the miniature laser system showed the proposed sensor is capable of achieving mm range resolution and sub mili-radian angular resolution when the distances between the sensor and ground is 1 meter of less. Innovative approaches in laser receiver design and signal processing algorithms provides the key elements required to achieve the desired performance in a small, lightweight sensor package and low unit cost. In the Phase I, ISC proposes to develop the GTOS baseline design configuration, signal processing approach and receiver focal plane array architecture. A proposed Phase I Option will develop the sensor readout IC (ROIC) unit cell circuit design.
