  • Patent number: 8620023
    Abstract: A method and apparatus for detecting objects. An object detector associated with a platform and configured to detect a number of objects is used to monitor for the number of objects. In response to detecting the number of objects, a number of distances to the number of objects detected by the object detector are measured using a distance measurement system. A number of geographic locations for the number of objects is identified using the number of distances, a location of the platform, and an orientation of the distance measurement system.

  • Patent number: 7258306
    Abstract: A system and associated method for compensating for thermal deformation of a spaced-based structure having a spacecraft payload. The system including a beacon source coupled to a first spacecraft for transmitting a first signal and a beacon sensor coupled to a second spacecraft for receiving the first signal and providing measurement data derived from the first signal. At least one attitude sensing device is coupled to the second spacecraft for determining estimated spacecraft attitude data for the second spacecraft. A processor on the second spacecraft is configured to process ephemeris data of the first and second spacecraft, beacon measurement data, estimated spacecraft attitude data, and gimbal angular position data to estimate spacecraft structural deformation.
