    摘要: A system and method of determining a pointing vector using two GPS antennas and a single GPS receiver is disclosed. Two stationary GPS antennas, with a separation preferably less than half of a wavelength (˜100 mm) may use a single receiver to determine the pointing vector of the system. Incorporation of a three axis angular rate measurement allows pointing determination during system rotation. Incorporation of three axis gyroscope system allows pointing determination while in motion. The system provides the ability to sense multipath and jamming. Also the system can potentially eliminate the impact and certainly alert the user that the measurement may not be reliable.

    摘要: An optical detector uses an auxiliary integrating capacitor is used to determine the optical flux rate when the charge on the well capacitor approaches or reaches linear saturation. The voltage across the primary linearly operating integrating well capacitor is monitored to detect its linear saturation. The auxiliary capacitor charges at a predetermined rate from the start of the integration interval, and the voltage across it is sampled when the monitored voltage across the primary linear integrating well capacitor reaches linear saturation. The voltage across the auxiliary capacitor at this point is function of the rate at which the primary well capacitor was filling, and this voltage is processed as the illumination level for the integration period.

    摘要: A light source is injected into an optical path of a camera to provide a controlled background to insure optimum uniformity of performance of the camera. An optical system, camera, image background measurement system, source intensity control, and light source comprise a closed loop control around the light source to control an operating point of the camera. Intensity of the light source is decreased as intensity of a background flux is increased.
