UWE-1 ( U niversity of W ürzburg E xperimentalsatellit) is a Pico - amateur radio satellite , which, with the help of the faculty of computer science and mathematics, by students of the University of Würzburg was built.
Data
UWE-1 is one of three student satellites that were launched into space by the European Space Agency's SSETI Express . On October 27, 2005, it was placed in 690 km high orbit. He was supposed to stay there for about three to five years until he was replaced by UWE-2 . The cube-shaped satellite weighs around 1 kg and has an edge length of 10 cm and thus corresponds to the Cubesat standard.
Down- / uplink frequency was 437.505 MHz, modulation was 9600 baud AFSK. The amateur radio call sign of UWE-1 was DPØUWE. The last contact with the satellite took place on November 17, 2005. An identical UWE test model was made available to the Deutsches Museum in Munich, where it will be exhibited in the space department together with a test model of the successor UWE-3 .
function
The primary task of UWE-1 was to carry out telecommunications experiments. Among other things, it was about data transmission on the Internet under space conditions: The current Internet protocols had to be adapted to the more difficult conditions in space - on earth, the transport of data on the web works very reliably, but in space delays and disruptions can increase occur. UWE-1 also served as a test laboratory for highly efficient solar cells , whose performance and durability were to be examined.
