TechnoSat

Nanosatellite for the Demonstration and Verification of Novel Components and Subsystems
Point of Contact

The TechnoSat project, which is funded by the German Aerospace Center (DLR), aims to design, build and start a nanosatellite. Primary mission objective of the TechnoSat mission is the demonstration and verification of newly designed components and subsystems for nanosatellites. The secondary mission objective is the design and operation of the adaptive and reusable nanosatellite platform TUBiX20. The adaptivity implies in this case that the platform can be adjusted to different payloads, orbits and mission scenarios. TechnoSat itself has a mass of approximately 20 kg and measures about 305 x 465 x 465 mm without antennas.

Lupe

TechnoSat carries several payloads:

 

Laser-Retroreflectors

Laser-Retroreflectors are implemented on satellites to enable high-precision range measurements. To this end, lasers on the ground are aimed at the satellite and the time required for the laser pulse to travel to the satellite and back again is measured. Usually, reflectors for laser ranging used on satellites are specially developed. The presented experiment on TechnoSat shall verify the suitability of cost-effective, commercial reflectors for laser ranging on small satellites. The experiment consists of 14 Laser-Retroreflectors distributed over the satellites outer surface each with a diameter of 10 mm. Before integration the reflectors have been characterised by the Helmholtz-Zentrum Potsdam - GFZ German Research Centre for Geosciences. Range measurements are carried out by the International Laser Ranging Service through various stations all over the world while the German Space Operations Center (GSOC) performs satellite orbit determination and propagation based on the distance information. The obtained laser ranging data are moreover used for studies regarding attitude changes of the spacecraft, which are executed by the Austrian Academy of Sciences (ÖAW).

Launch and Operations

TechnoSat was launched as 12th satellite of Technische Universität Berlin on a Russian Soyuz 2.1 rocket on Friday, July the 14th at 8:36 am Central European Summer Time into an 600 km Sun synchronous orbit. After successful launch the satellite's beacon, as well as first telemetry was received during the first pass over the ground station in Berlin. Currently, commissioning of the payloads, as well as platform experiments are being performed.

Further steps will be announced on the News page of the Chair of Space Technologies of Technische Universität Berlin.
