Relative position control device by output measurement for one spacecraft in a spacecraft group that forms a formation

摘要

The device has three send/receive antennas (A1-A3) installed on an observation satellite of a group of satellites and sending/receiving radio frequency signals. A measurement unit (MM) delivers power sets associated with one of the other satellites. A storage unit (BD) stores cartographic data sets representing powers of the signals received by the antennas based on transmission directions. A processing unit (MT) compares each power set with the data sets to estimate the directions of the signals sent by the satellites with respect to a reference system tied to the observation satellite.
