As prime for the scientific-technical payload and responsible for the military repeater, Tesat-Spacecom is responsible for the design, construction and verification of the core elements of the German space mission “Heinrich Hertz”.
Aladin’s magic lamp ready for take off: After 16 years of preparation and tough technical difficulties, Aeolus is finally ready to go for its final destination in low earth orbit. Weighing 1.4 tons, Aeolus carries the payload “Aladin”(Atmospheric Laser Doppler Instrument), which is based on the concept of LIDAR (Light detection and ranging), a method related to RADAR, but with laser beams for distance measuring instead of radio waves.
After getting online Aeolus will help improve weather forecasts and be of high importance for climate research, since through its new technology it will be possible to perform global wind measurements for the first time from the ground up to a height of 30 kilometers.
For the success of this mission, Tesat supplies several Reference Laser Units (RLU) and a subsystem.
We keep the fingers crossed that the launch will not have to be delayed a second time and the current window to be final, opening tomorrow night at 23:30 CEST.

Recently an editor of the VDI-Nachrichten paid us a visit for his research on laser communications and EDRS-C, having no fear bringing our experts to their limits and asking difficult and uncomfortable questions. The result is an exciting and extensive article with the headline „Lichtgestalt“ („Shining Light“).
The article describes our LCT135, which we developed and produced in cooperation with DLR IKN, and its role within Airbus’ SpaceDataHighway.
Many thanks to Iestyn Hartbrich for the well-written article.

The final countdown for Tara, Samuel, Anna and Ellen begins: Only 1 hour and 30 minutes until the new Galileo satellites are launched into orbit onboard an Ariane 5 launcher.
In short: the European Galileo program is the counterpart to the US GPS system and is though an independent, global satellite navigation system. Tesat-Spacecom's part for the four new satellites was to deliver the essential TT&C transponders, which are being used to properly determine the position of an object in space and though are crucial for a satellite-based positioning serivce.
The launch can be found at this link, the launch is today at 13:00 CEST.

Tesat takes part in European Union’s research and innovation programme Hi-FLY to take RF data links to the next stage. But let’s first clarify: What is the Hi-FLY project? And why is it so important?
Berlin, 26.04.2018: At today’s press conference Airbus Defence and Space, the Institute for Communication and Navigation of the German Aerospace Center (DLR-IKN) and Tesat-Spacecom published their cooperation with the aim to equip the ISS with a high capacity direct-to-earth Laser Communication Terminal.
Backnang, 12.04.2018: Tesat's Laser Communication Terminal for CubeSats, CubeL, is on track after recently the Critical Design Review (CDR) was successfully held at the German Aerospace Center (DLR) in Oberpfaffenhofen. This was an important milestone for the development program on the way to its demonstration mission, which is planned to launch later this year.
Satellite communication reaches new peak
Backnang, 11.04.2018: Tesat-Spacecom established 10,000 connections between satellites using its Laser Communication Terminals (LCT). Tesat's LCTs transmit massive amounts of data at up to 1.8 Gbps over distances of 80,000 km in orbit. In addition, the company develops significantly smaller LCTs for Direct-to-Earth applications.
Backnang, 21.02.2018: Exactly ten years ago on 21st February, 2008, a government-to-government cooperation between the United States and Germany to establish a laser link between two operational satellites in Low Earth Orbit (LEO) started a new chapter in the history of space. The German radar satellite TerraSAR-X and the U.S. Missile Defense Agency satellite NFIRE, both equipped with Laser Communication Terminals (LCT) manufactured by Tesat-Spacecom, established the first successful and stable orbital laser link.
The LCT135 with its 135 mm narrow aperture is the smallest terminal in the geostationary orbit. Working in a daily routine it is the powerhouse within the European Data Relay System called SpaceDataHighway. Under the ESA ScyLight program Tesat-Spacecom has now spawned the next evolution step for our well known GEO Laser Communication Terminals LCT135, by further developing and implementing new additional features to make even more applications possible. Therefore the GEO LCT135 will get – beside other new features – a data rate upgrade to nearly 4 Gbps, and a flexible and switchable mode between LEO and GEO scenarios to enable laser links over distances of 80,000 km in space in just seconds.
