SMARTnet(TM) - First Results of the Telescope Network

Situation awareness of objects in the geostationary regime is of great interest for collision avoidance by active satellites as well as for scientific research on the space debris population and their evolution over time. As the number of satellite operators and researches in this field is large, it makes sense to set up a sensor network with multiple entities to combine all available sensor measurements for a comprehensive situational picture. This will allow for cost sharing and optimising observation strategies to gain as much information as possible about the desired objects. Therefore, the German Space Operation Center, GSOC, together with the Astronomical Institute of the University of Bern, AIUB, are setting up a global optical sensor network called SMARTnet(TM): the Small Aperture Robotic Telescope Network. The main objective is the free exchange of all information gathered, mainly in form of tracklet observations, within all partners involved. In this paper, the principles of SMARTnetTM are presented, how other entities can join the network and how tracklets are exchanged. The first two stations at Zimmerwald and Sutherland are introduced as well as possible future locations for additional telescope stations. Furthermore, results from the first two stations are shown. Additionally, a short insight is given in the data processing chain like object correlation, orbit determination, and cataloguing function
