Design of MEMS Based Attitude Determination and Control System for Nanosatellite
-One of the latest manifestations of miniaturization in space applications is the development of standardized nanosatellite. Recent achievements and future trends of Micro-Electro-Mechanical Systems (MEMS) technology have indicated that microtechnology is the critical technologies of future space programs. Enabling technologies for demanding applications will surely make use of MEMS based compo...
متن کاملAn Attitude Control System and Commissioning Results of the SNAP-1 Nanosatellite
SNAP-1 is a low-cost nanosatellite build by Surrey Satellite Technology Ltd. (SSTL), it is amongst other objectives a technology demonstrator for 3-axis stabilisation and orbit control for a future constellation of small satellites during formation flying. The satellite uses a single miniature Ymomentum wheel, 3-axis magnetorquer rods and a single butane gas thruster to ensure a nominal nadirpo...
متن کاملFree Molecule Micro-resistojet: Nanosatellite Propulsion
Constellations and platoons of small satellites can offer an assortment of benefits over larger, single function spacecraft. The strict mass, volume, and power limitations of small satellites will require unique micro-technologies to help develop efficient propulsion systems for maneuvering. The Free Molecule Micro-Resistojet (FMMR) has been analyzed and tested in this study to determine its ap...
متن کاملAas 03-100 Integrated Orbit and Attitude Control for a Nanosatellite with Power Constraints
Small satellites tend to be power-limited, so that actuators used to control the orbit and attitude must compete with each other as well as with other subsystems for limited electrical power. The Virginia Tech nanosatellite project, HokieSat, must use its limited power resources to operate pulsed-plasma thrusters for orbit control and magnetic torque coils for attitude control, while also provi...
متن کاملA Novel Adaptive Unscented Kalman Filter Attitude Estimation and Control System for a 3U Nanosatellite
A novel adaptive unscented Kalman filter (AUKF) based estimation algorithm is proposed for a 3U Cubsat. This small satellite employs a three axis magnetometer and three MEMS gyroscopes as well as three magnetic torque rods and one reaction wheel on the pitch axis. Unlike the existing UKF, in this paper, an n+1 sigma set is used to estimate the nanosatellite attitude instead of 2n + 1 sigma poin...
