With the launch of the first CubeSat a trend of easy access to Low Earth Orbit was started. Today many educational institutes around the world design, build and operate CubeSats for educational as well as scientific purposes. This paper presents designs and development in hardware and software made to achieve a flexible ground segment at the Luleå University of Technology Space Campus in Kiruna, Sweden. The existing ground station is adapted to support more frequencies and modes of operation to enable future satellite projects at the university easy access to space communications. New equipment has been procured and integrated with existing equipment in a new location using a 19-inch server rack. The article presents a ground segment design using software-defined radio to promote flexibility and adaptability. A in-house developed sequence control board is presented that enables the ground station to quickly switch between full duplex and half-duplex modes.
