Satellite formation coordination control was important of reducing the total control fuel cost and keeping the formation safe. If one of the formation satellites was malfunctioned, which loose the orbit maneuver ability, then, the other satellites should transfer to a new position to keep the formation safe. Meanwhile, the malfunctioned satellite can be replaced by a new satellite in the new formation...
How to balance each satellite fuel consumption during the period of satellite formation keeping, which can increase the total life span, is of great importance. For the plane circle formation which center was a virtual satellite, a new formation keeping control method was presented considering the fuel equalization constraint. The satellite which remain fuel was the least was chosed to be the reference...
The online estimation of spacecraft center of mass (CM) plays an important role in the attitude and orbit control law design of large variety mass property spacecraft. Based on spacecraft motion equation, the method of using one point three orientations acceleration together with gyro information to estimate CM was discussed, the main error source and requirement of angle velocity was analysis. Then,...
