In this paper a Parallel Manipulator (Stewart Platform) is used to align and maintain the position of the photovoltaic panels in relation to the Sun. The system is designed on a Stewart platform with two degrees of freedom providing a significant advantage towards reaching the maximum accuracy and economy for this positioning task. To avoid measurement the(More)
Active magnetic control have been used to develop the rotating stabilization of tethered nano-satellites. It uses magnetic control to stabilize the orbit position by controlling angular velocity of rotating TCS. The system uses Earth's magnetic field as energy source to interact with a long conductive tether and consecutively reach the rotational stability(More)
In this work a parallel manipulator (Stewart platform) is used to align and maintain the position of the secondary mirror of a radio-telescope. The six degree of freedom platform gives the significant advantage to reach the maximum performance for the positioning task. This system uses six lineal actuators with changeable lengths to obtain the desired(More)
