GNSS/INS (Global Navigation Satellite System/Inertial Navigation System) systems have found widespread usage in industry, especially in automated agriculture. Automated agriculture requires high frequency, precise, steady and smooth attitude solutions. This necessitates smooth error patterns in navigation solutions. Given that navigation solutions can be derived from different information sourc...

The growing population of space debris poses an increasing threat to spacecraft operating in low Earth orbit. By taking advantage of aerodynamic drag, a gossamer sail can be used to dramatically reduce the time it will take for a satellite to deorbit. In addition to rapid deorbit time, a gossamer sail also offers the capability of stabilizing a satellite’s attitude. The deployment system utiliz...

This paper investigates alternate control techniques for the attitude control of a three axis stabilized flexible communications satellite consisting of a large reflector and a solar array. The control configurations consisted of three classes: Class 1 sensors and actuators co-located on the central body, Class 2 actuator on the central body and sensors distributed, and Class 3 -actuators and s...

For most satellite missions, it is essential to decrease the satellite angular velocity. TheΒ algorithm is a common algorithm to stabilize the spacecraft by using magnetorquers. Controlling the satellite using the magnetorquers is part of the attitude control subsystem detumbling mode. Due to oscillating disturbances in the space environment, the required initial conditions needs analysis. As a...

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...
