The most important step, the deployment of the antennas, took place 30 minutes after the orbit insertion. This activity, which his conducted autonomously by PEGASUS, is one of the most critical ones. Fortunately, everything worked as planned and the first beacon was received only 3 hours after the launch by the ground station network of PEGASUS (http://spacedatacenter.at/pegasus/index.php). Since then, the ground station network established by the Space Technology Group, is continuously receiving data from the Satellite. The information contained in the beacons allow a preliminary assessment of the satellites functionality and health. Following the establishment of a sound communication with the satellite, the downloading of the so-called House Keeping Data (HKD) was initiated. They HKD contain a comprehensive summary of all relevant satellite parameters and subsystem status such as temperatures, voltages, current values, magnetic field measurements, gyration data and many more. In total, the HKD contains 40 parameters with a time resolution of 1 second over the complete mission time. Nearly all subsystems of the satellite are by now commissioned. Beside of the nominal operation the following activities were conducted as part of the commissioning phase during the last months:
• Successful commissioning of the GPS
• Successful deployment of the MagBoom (for magnetic field measurement)
• Deployment of the Langmuir probes (unfortunately no feed-back available if deployment is successful)
• Activation of the Attitude Determination and Control System and de-tumbling of PEGASUS
