Attitude Determination for the Pico-Satellite UWE-2
نویسندگان
چکیده
Modern miniaturization technologies enable the realization of very small satellites at masses below 1kg, nevertheless limited attitude determination and actuator performances raise challenging control problems. Specific attitude determination aspects discussed at the example of UWE (University of Wuerzburg Experimental satellite), a standardized pico-satellite platform related to technology demonstration and space research. UWE-1 is in orbit since October 2005 and successfully completed its mission on telecommunication experiments. The successor satellite UWE-2 is focusing on an advanced Attitude Determination System (ADS) based on miniature sensors. This paper will address implementation details for the ADS, presenting in particular results from the performance evaluations in simulations and tests.

Networked Control of Cooperating Distributed Pico-Satellites
In spacecraft engineering a paradigm shift is emerging with the tendency from traditional, single, large, and multifunctional satellites towards cooperating, distributed small spacecraft systems. In particular modern miniaturization techniques allow realization of satellites with continuously smaller masses, and thus enable cost-efficient implementation and launch of distributed multi-satellite...
متن کاملRobust UKF Insensitive to Measurement Faults for Pico Satellite Attitude Estimation
In the normal operation conditions of a pico satellite, conventional Unscented Kalman Filter (UKF) gives sufficiently good estimation results. However, if the measurements are not reliable because of any kind of malfunction in the estimation system, UKF gives inaccurate results and diverges by time. This study, introduces Robust Unscented Kalman Filter (RUKF) algorithms with the filter gain cor...
