A NEW FAMILY OF LOW COST ATTITUDE CONTROL SENSORS

摘要

This paper presents the development status of a new optical sensors generation suited to the satellite attitude measurement requirements. These sensors are : A new two axis fully static infrared Earth horizon sensor (now qualified) designed to measure pitch and roll of the attitude of a three-axis stabilized spacecraft with respect to the Earth horizon. A new multi-purpose, fully autonomous and low cost star tracker. This star tracker (now qualified) provides the attitude control subsystem with 3-axis attitude as well as the satellite angular velocity. A new Sun sensor designed to measure pitch and roll of a spacecraft with a very low cost and low mass.
