UWE-3 ( U NIVERSITY W ürzburgs E xperimentalsatellit 3) is a German Experimental satellite , the November 21, 2013, a Dnepr-1 from Dombarovsky started successfully.

history

After UWE-1 and UWE-2 , it is the third picosatellite built by students from the University of Würzburg . The project was funded by the Federal Ministry of Economics and Technology until the end of 2014. With a weight of one kilogram and a diameter of ten centimeters, UWE-3 is just as heavy and large as UWE-2.

aims

The scientific objectives of the construction of the small satellite are:

  • Extension of the attitude determination system to the attitude control system
  • Test of robust hardware and software designs based on commercially available hardware under space conditions

Course and results

The mission goals could be achieved by the end of the one-year funding. Two months later, in spring 2015, new sponsors were found for another multi-year operation. Several software updates were made to the on-board computer to improve position control, among other things. The device, including the power supply with a battery, is technically in excellent condition even after four years (as of May 2018) in space. A temporary failure of the transmitter could be remedied by an automatic restart. The mission is monitored, among other things, with the help of private radio amateurs who receive and forward the data sets sent daily on the operating status. With the received attitude control data it was even possible to create a simulation film that clearly shows the flight of the rotating satellite over Würzburg.
