The TET ( T echnology e rprobungs t räger) program is a microsatellite program of DLR as part of the OOV program (On Orbit Verification). It is intended to offer the German industrial and research community the opportunity to verify new technologies in space in order to strengthen the market opportunities of the corresponding technologies on the international space market. Two satellites were originally planned, TET-1 starting in 2010 and the option TET-2 starting in 2011. They are based on the bus system of the small satellite BIRD .
The following eleven payloads were selected for testing for TET-1:
- several new solar cell types
- a lithium-ion battery system
- an infrared camera for fire observation
- a temperature measurement system based on commercial components
- a semiconductor memory
- a two-frequency navigation system ( GPS / Galileo )
- a hardware on-board computer system
- a pico satellite propelled it
- an HF data transmission system
The main contractor for phase A (feasibility) was IABG , in particular payload accomodation. Phases B and C / D (Detailed Definition / Qualification and Production) were completed at the end of 2010. The satellite was built by a consortium of companies led by Kayser-Threde GmbH . Kayser-Threde GmbH was the main contractor and responsible for the integration of the payloads and the development of the payload supply system. The satellite bus was developed and built by Astro- und Feinwerktechnik Adlershof GmbH in cooperation with DLR. The environmental qualification was carried out in the IABG space test center.
The launch should take place in March 2011 as a secondary payload on a Soyuz / Fregat from Baikonur . Due to problems with the two main payloads, the Russian Kanopus volcano and the Belarusian BelKA-2 satellite, this was postponed several times. The launch had to be postponed again in June 2012 because the Russian and Kazakh authorities failed to reach an agreement on the crash zones for the first rocket stages. On July 22, 2012 at 06:42 a.m. ( UTC ), the launch was finally carried out successfully.
