With the help of European ham radio operators, Aalborg University engineering students have established two-way communication with their home-built, ESA-sponsored satellite AAUSAT5.
AAUSAT5 was launched from the International Space Station on 5 October2015. Following initial difficulties in establishing a two way communication link with the satellite from the control centre in Aalborg and attempts to improve the ground station performance, the investigation revealed that the northern location of Aalborg, relative to the satellite’s orbit, was a contributor to the communication issue. Therefore the project team reached out to ham operators in more southern locations in Europe for help.
Aalborg University sent special equipment down to a German ham radio operator. From his location south of Frankfurt, this operator now acts as the relay station between the student’s control centre in Aalborg and the satellite whenever it passes over Europe. In this way, communication has been established.….. READ MORE
