    Abstract: A hybrid laser countermeasure line replaceable unit and method of upgrading therewith is provided. The unit includes two generable laser beams, namely, a first pulsed laser beam and a second continuous wave laser beam. Further embodiments may have multiple pulsed and continuous wave laser beams as necessary. The two beams in this single unit either may be generated from a single gain medium or may be generated from multiple gain mediums inside the line replaceable unit. The two beams may be combined if necessary to provide greater likelihood of success as a countermeasure to defend against optically guided incoming threats to a vehicle, such as military aircraft.

  • Network test system
    Patent number: 9825842
    Abstract: A network test system seeks to improve visibility into the real-time operation of a network system or subsystem of a spacecraft through the use of a port from each relevant network to a spacecraft test interface. The network test system includes a packet switch operatively coupled downstream from a SERDES receiver and operatively coupled upstream from a SERDES transmitter. The packet switch in conjunction with the signal replicator in the SERDES receiver taps off a data stream of the network activity so that the port allows an observation device to passively observe the network activity. The system is adapted to increase real-time observation of network activity without disturbing the network.
