Title: Hybrid Guidance System for Relative Navigation
Agency: NASA
Contract: NNG06LA29C
Award Amount: $69,990.00


Future NASA architectures and missions will involve many distributed platforms that must work together. This in turn requires guidance, navigation and control (GN&C) technology such as systems that determine spacecraft relative range and attitude. The proposed Hybrid Guidance System (HGS) will be such a system, providing increased relative navigation accuracy and robustness while reducing mass, volume, and power consumption by a factor of 2 to 4. The HGS's key innovation is integration of three proven and developed sensor technologies (laser-based retro-image pattern matching, laser range-finding, and correlation) into a low-power package. We will develop non-linear navigation estimation algorithms to fuse the sensor outputs together as well as to integrate the system output with other on-board navigation systems. The state estimate generation using three different techniques will increase the system's robustness through the ability to reject faulty measurements from one component of the system. Phase I of the SBIR will verify feasibility of the HGS design and the navigation algorithms and will culminate in a realistic mission simulation of vehicles using the HGS as part of an integrated GN&C system. The results of this simulation will serve as an excellent springboard to Phase II HGS prototype hardware and embedded software development.
