Abstract

Systems, methods and apparatus related to a self-preservation/self-protection system (SPS). The SPS system includes a local area situation awareness sensor suite (LASASS), multiple central pattern generator (mCPG) decision circuitries and related actuators. The SPS system utilizes the LASASS, mCPG circuitries and actuators to perform the desired processing and effectuate changes in the position of an object to be detected or avoided.

one or more navigation sensors configured to acquire navigation data relative to the spacecraft and provide the acquired navigation data to the guidance control circuit and the mCPG circuits, the mCPG circuits generating a related pattern control signal; and
one or more actuators configured to receive one or more guidance control signals from the guidance control circuit and one or more pattern control signals from the mCPG circuits to actuate one or more mechanisms of the spacecraft to adjust a position of the spacecraft based at least in part on the received guidance control signals from the guidance control circuit and based at least on a larger part on the pattern control signals from the mCPG circuits.
