In early 1990’s Danish companies, universities, and research institutions - with active economical support by the Danish government - started an ambitious program to design and develop a domestically built satellite, the Ørsted satellite.
The result was a huge success: the Ørsted satellite was launched in 1999 and was operated for more than 10 years.
AAU did provide attitude determination and control design and software hosted a secondary groundstation.
This was - of course - gained with high interests from the students and they more or less requested a cubesat project to be launched.
And as a consequence AAU Cubesat was initiated in 2001.
The rest is history :-)
A cubesat is 10cm x 10cm x 10cm with a weight of 1 kg.
