On February 1st 2018, one of the first nanosatellite networks ever was successfully deployed in space.
The platform and its main components were developed by TU Berlin during the S-NET project. Main features of the platform are:
– 10 kg class
– single point of failure tolerance on component level
– 3-axis attitude control
– optimmized for distributed missions
The S-band transceiver SLINK was developed in cooperation with the company IQ wireless. The system works on S-band frequencies and uses modern transmission methods, such as adaptive coding and modulation schemes. The protocol enables network communication with several nodes. The following parameters make SLINK ideal for nanosatellite payload:
The newly developed deployment system for nanosatellites was produced jointly with the company Astro- und Feinwerktechnik Adlershof. The lifetime of the mission depends highly on the orbit injection accuracy of the nanosatellites from the rocket upper stage. Hence, the system ensures most precise deployment during separation.
The relative distance control was realized via utilizing differential drag between the satellites by changing the attitude w.r.t to flight direction.
The respective TLEs are: 43186, 43187, 43188, 43189.
