摘要
Abstract
Compared to the traditional earth observing satellites,theoretically,agile satellites can maneuver rapidly along three axes and accomplish imaging mission of strip targets in any direc-tion.As for this application,an active scanning imaging mode is proposed on general track.In the process of active scanning,three angles of satellite attitude are changing continuously.The atti-tude planning algorithm is built which can be applied to active scanning process.For the time se-quence planning of one-orbit imaging mission of strip targets,the start imaging time model is built.The SQP (sequential quadratic programming)algorithm is used to solve these equations. Simulation result on a typical scenario validates the planning algorithm of imaging processes.For the imaging quality maintenance,the influence of satellite’s attitude accuracy and stability during active scanning process is analyzed.The engineering controlling requirement is proposed which can be used in the working mode design of satellite.关键词
