  • Publication number: 20040193373
    Abstract: A method and system for continuously monitoring a constellation of Global Positioning System (GPS) satellites from space is disclosed. The system utilizes a plurality of GPS receivers respectivelyinstalled on-board the GPS satellites. The on-board GPS receivers receive the navigation signals transmitted by its host GPS satellite in addition to the navigation signals from all of the GPS satellites in view. The system further utilizes a Kalman filter which can also be installed on-board one or more of the GPS satellites in space to achieve further isolation from the master control station. The method comprises the steps of providing a plurality of GPS receivers on-board the GPS satellites and substantially continuously receiving at the GPS receivers navigation signals from the GPS satellites in view of the GPS receivers, and continuously determining a range from the navigation signal of each GPS satellite in view of the GPS receivers.

  • Patent number: 4155096
    Abstract: To boresight the laser of a laser designator system to the null point of an automatic television tracker, by selectively causing the laser beam to be retroreflected to the video sensor of the system, which interfaces with a television tracker. The tracker locks onto the retroreflected laser spot, with the tracker error signals, in a feedback control loop, being used to control the video sensor raster bias to center the sensor sweeps about the laser spot, thereby nulling the tracker error signals and achieving boresight with the laser automatically.
