Abstract: Technology for measuring orientation is described. Signals can be received from a signal source having a known location via at least two antennas of the interferometer that are separated by a predefined distance. A delay between receiving the signals from the signal source at the at least two antennas of the interferometer can be calculated. A line of bearing (LOB) of the interferometer with respect to the signal source can be determined based on the delay between receiving the signals at the at least two antennas from the signal source. The orientation of the interferometer can be measured in a global coordinate system using the LOB of the interferometer with respect to the signal source.

Abstract: An auction-based distributed method for cooperative multi-target tracking by a plurality of satellites, includes distributed target tracking error and utilization computation as an auction bid across the satellite and uses message-passing to find best bid, handles different tracking requirements via definition of bids and modification of task definition used during the bidding process, and selected a list of auction winners to track the target.

Abstract: A method including: receiving, at a given satellite, a target list, the target list identifying a plurality of targets; identifying a plurality of satellites of which the given satellite is part; generating, at the given satellite, a plurality of satellite-target pairs, each satellite-target pair including a respective one of the plurality of targets and a respective one of the plurality of satellites; identifying a plurality of costs, each of the plurality of costs corresponding to a different one of the plurality of satellite-target pairs; identifying, by the given satellite, a plurality of assignment pairs, the plurality of assignment pairs being identified based on the plurality of satellite-target pairs and the plurality of costs, each of the plurality of assignment pairs including a respective one of the plurality of targets and a respective one of the plurality of satellites that is assigned to track the respective target.
