UWE-2

UWE-2 (University Würzburg's Experimental satellite 2) was a follow-on picosatellite technology demonstration project within the CubeSat family standard, developed and built by students of the University of Würzburg, Germany. The overall objective is to demonstrate the capabilities of attitude determination and control in picosatellites.^[1]

Mission

Integration of UWE-2 in the cleanroom

Developed by the University of Würzburg, its scientific objectives are:

• tests of methods and algorithms for attitude determination
• optimisation of internet protocol parameters, in order to adapt to the specific space environment.

Launch

On 23 September 2009, at 06:21 UTC, UWE-2 was launched by a Polar Satellite Launch Vehicle (PSLV) launch vehicle (PSLV-C14) together with Oceansat-2 and three further CubeSats in a polar orbit at 720 km altitude. Successful operations could be initiated. Use of SPL (Single Picosatellite Launcher) of Astro und Feinwerktechnik Adlershof GmbH (Berlin), Germany, for the deployment of the CubeSats.^[1]

UWE-2 followed the earlier UWE-1. UWE-3 is also planned.
