Tubsat-N

TUBSAT -N and N1 were the first nano-satellites of the Institute of Aeronautics and Astronautics (ILR ) at the TU Berlin. The development and construction of the satellites took over the ILR, with project management by Prof. Udo Renner, funding was provided by the Federal Ministry of Education and Research. The satellites were communications and technology test satellite.

The satellites were launched together as a coupled system and have been separated from each other in orbit. The idea was to launch this a stack of up to ten TUBSAT -N1 satellite together and only separated in orbit at independent platforms. Each of the sub-satellites could have taken over their own tasks. However, the money was only enough for two satellites.

Mission History

The launch took place on 7 July 1998 with a Russian Schtil -1N rocket. For the first time satellites were thereby brought from a submerged submarine, the K -407 Nowomoskowsk, into orbit. The launch site was located in front of the Kola Peninsula in the Barents Sea.

The communication experiments were essentially those of TUBSAT -A but with more modern technology and significantly reduced volume and mass requirements. The planned re-entry into the atmosphere took place a year later.
