Modeling and Control - Flexible Structure Spacecraft

Installation dynamics, optimal thruster propulsion, and specific impulse thrust for reignitable fuel motors to regulate pointing error is obtained for geosynchronous (e.g., the Indian National Satellite, INSAT–1B), and sunsynchronous (e.g., the Indian Earth Resource Satellite, IRS–1) satellites parked in transfer orbits. Filter dynamics for slow and fast terrestrial system are obtained. Design for inter satellite link server to maximize drop outlets is given. Technique for extension of commutative rings for coordinated control and communication systems with predetermined target signature in global and protected environment is given. Visibility model of flexible structure terrestrial exploration space monitoring station with associated space coordinate system is given. Technique proposed is applied for information acquisition and synchronization of inertial targets. Design of long range navigation in projective space and robust hybrid controller for AAFM auto pilot system is given. AAFM system reliability is analyzed.
