Attitude Control System for Arc-Second Stabilization of 30-kg Micro Astronomy Satellite
نویسندگان
چکیده
This study focuses on the development of a precise attitude control system for small satellites. In general, conventional methods used for attitude control in standard-sized satellites are not applicable to small satellites because of constraints of power consumption, space requirements, and mass. In addition, small satellites are more greatly affected than standard-sized satellites by attitude disturbances because of their relatively small moment of inertia. Although magnetic disturbance is considered negligible in standard-sized satellites, it is dominant in small satellites. To realize precise attitude control in small satellites, the satellite should use an attitude control method that satisfies the abovementioned constraints and reduces the effect of magnetic disturbance. This study proposes a new method to solve these problems. Through an example of an astronomical observation mission using small satellites, it is demonstrated that precise attitude control is feasible in small satellites.

Application of Magnetic Sensors to Nano- and Micro-Satellite Attitude Control Systems
These days, nano (1 kg – 10 kg ) and micro (10 kg – 100 kg) – satellites, which are smaller than conventional large satellite, provide space access to broader range of satellite developers and attract interests as an application of the space developments because of shorter development period at smaller cost. Several new nanoand micro-satellite missions are proposed with sophisticated objectives...
متن کاملFinite-time stabilization of satellite quaternion attitude
In this paper, a finite-time control scheme is presented for stabilization of the satellite chaotic attitude around its equilibrium point when its attitude is confused by a disturbed torque. Controllers and settling time of stabilizaton are obtained, based on the Lyapunov stability theorem and finite-time control scheme. This method is satisfied for any initial condition. Numerical simulations ...

Celestial positioning has been used for navigation purposes for many years. Stars as the extra-terrestrial benchmarks provide unique opportunity in absolute point positioning. However, astronomical field data acquisition and data processing of the collected data is very time-consuming. The advent of the Global Positioning System (GPS) nearly made the celestial positioning system obsolete. The n...
