Development of SIS - Satellite controller Integrated with Star sensors -
نویسندگان
چکیده
SIS is a Satellite controller Integrated with Star sensors, which has been developed as a prototype model of a compact, low-cost satellite controller. SIS integrates attitude sensors into a star sensor and integrates several electronics for star identification, attitude determination, attitude control, and data handling into a single processing unit. SIS meets high reliability requirements by adopting a modified voting system even though it employs high performance commercial parts to increase the calculation speed. Consequently, we can drastically decrease the size and cost of the satellite controller. SIS will be included in the payload of the SERVIS-1 satellite scheduled for launch at the end of this year.

متن کاملDesign and evaluation of a digital processing unit for satellite angular velocity estimation
A satellite’s absolute attitude and angular rate are both important measurements for satellite missions that require navigation. Typically, these measurements have been made by separate sensors, with star cameras being used to determine a satellite’s absolute attitude, and gyroscopes being used as the primary rate sensors. Recently, there have been multiple efforts to measure both of these quan...
