UWE-1

UWE -1 ( University of Würzburg, Experimental Satellite) is a pico amateur radio satellite, which was built by students at the University of Würzburg.

Data

UWE -1 is one of three student satellites of the European Space Agency were shot into space from the SSETI Express. On 27 October 2005, he was placed in a 690 km high orbit. There he was to remain for about three to five years, until he is replaced by UWE -2. The cube- shaped satellite is about 1 kg and has an edge length of 10 cm and thus corresponds to the CubeSat standard.

Down-/Uplink-Frequenz was 437.505 MHz, modulation was 9600 baud AFSK. The amateur radio call sign of UWE -1 was DPØUWE. The last satellite contact on 17 November 2005. A structurally identical UWE test model was made ​​available to the Deutsches Museum in Munich is available, where it is issued together with a test model of the successor UWE- 3 in the aerospace department.

Function

Task of UWE- 1, it was primarily to conduct telecommunications experiments. This is discussed included data transmission over the Internet under space conditions: it was to adapt the standard Internet protocols to the difficult conditions in space - on earth but does the transportation of data on the Web very reliable in space can be amplified delays and disorders. occur Furthermore served UWE -1 as a test laboratory for high-efficiency solar cells whose efficiency and durability should be investigated.
