"Thirty-three minutes after the launch, we established radio contact with the 2.5-ton COMSATBw-2 satellite via the antennas of the Indian ground station in Bangalore. Seventy DLR scientists and engineers were involved in taking control of the spacecraft," reports Thomas Kuch - Director of Mission Operations for the German Space Operations Center (GSOC) - at DLR Oberpfaffenhofen. GSOC has been running successful space missions since 1968. At present, DLR has five satellites for scientific and commercial Earth observation under its control, as well as the European research laboratory Columbus on the International Space Station (ISS).
COMSATBw-1 in orbit since October 2009
In October 2009, flight engineers at GSOC took control of COMSATBw-1, the Germany armed forces' first communications satellite. "COMSATBw-2 will also be positioned by the Space Operations Center in a geostationary orbit over the next few weeks, at an altitude of approximately 36,000 kilometres. In other words, it will be 'parked' in its intended orbital position," explains Thomas Kuch as he runs through the next steps for this mission. This will be followed by the 'commissioning' or initial operation of the satellite subsystems. Antennas and solar panels will be deployed and subjected to in-orbit tests lasting several weeks. In the course of these tests, the satellite will be configured for its intended application.
"Following the successful operational acceptance of COMSATBw-2 in orbit, the new satellite system will be handed over for regular operations, which are scheduled to last for the next 15 years. At DLR, 30 members of staff will be involved in these operations," states Mission Operations Director Kuch.
The satellites COMSATBw-1 and COMSATBw-2 form part of the German armed forces' SATCOMBw programme. Alongside the two communications satellites, this system includes stations and monitoring equipment on ground, and - for the first time - it facilitates autonomous, worldwide transmission of voice and data as well as video and multimedia applications. The entire system is scheduled to commence full-scale operations by early 2011.
