Mini-satellites, laptop satellites, cubesats and other concepts reflect a new type of satellite:
Cheap, easy to realise and easy to launch – but easily lost in space in some cases. The Distributed Ground Station Network (DGSN) is a solution that matches this new approach to satellites. DGSN is a network of small ground stations, each of which will receive a wide spectrum of radio frequencies.
Each received signal will be time-correlated with an on-board GNSS system. When at least five ground stations receive the same signal, an algorithm can position the signal and track it via multilateration. The resulting data will be transmitted via the internet to a central server. In summary, DGSN provides communication links to smallscale missions, facilitates tracking of small satellites, and offers important raw and positioning data to satellite owners. With the DGSN, tracking cubesats could hardly be easier thanks to the following characteristics:
› Faster than services currently on the market
› Global in scope
› Reasonably priced
Thanks to DGSN, no mission will be lost in space.
«The Distributed Ground Station Network (DGSN) is the fitting solution for cubesats and other small satellites: the low budget solution based on open source provides new services to this dynamic new market.»
