    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.
  • VDI-Nachrichten: Shining Light

    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...
  • Live: Launch of 4 new Galileo satellites

    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...
  • Tesat-Spacecom participates in EU research and innovation programme Hi-FLY

    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?
  • Gigabit Connectivity for the International Space Station

    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.
  • World's smallest Laser Communication Terminal from Tesat on track - CDR...

    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.
  • 10,000 laser links between satellites established

    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.
  • Tesat celebrates 10 Years of Laser Communications in Space

    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...
  • Advanced capability evolution for optical Laser Communication

    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 –...
  • Live: Launch of SES-14 and Al Yah 3

    Tomorrow, on the 25th January, at 23:20 CET (live stream starts at 22:05 CET) an Ariane 5 ECA will launch two satellites - the SES-14 and the Al Yah 3 - into a geostationary transfer orbit. A rocket launch per se is a event you don't want to miss, but - needless to say - for us it's always a very special moment when our equipment gets shot into space, such as a variety of Ku- and Ka-Band OMUXes, IMUXes, Switches, Filters and MPMs.
  • Live: Launch of Sentinel-5P

    Today at 11:27 am CET the European Sentinel-5P satellite of the Copernicus program starts with a Rockot from Plesetsk Cosmodrome in northern Russia. In addition to the great fact that this launch is one of the few that takes place during the day and you do not have to stay up late or get up early, the mission of the Sentinel 5P is a remarkable one: With its state-of-the-art Tropospheric Monitoring Instrument (Tropomi), it measures a variety of trace gases such as nitrogen dioxide, ozone,...
EDRS-A launch
Tesat decisively involved with Laser Communication Terminal and Relay Payload

PI1272 – Backnang, 04.02.2016: On January 29, 2016, the first laser node of the European Data Relay Satellite System (EDRS) was successfully launched into the orbit on board a Proton missile at 11:20 pm Central European time. The Eutelsat 9B telecommunication satellite reached its destination at around 36,000 kilometers above the equator after a nine-hour flight time, where it is now subjected to in-orbit tests.

With this great step for intersatellite communication, the cornerstone for the new data highway in space has been laid, with which up to 50 terabytes of data from the orbit can be sent to Earth every day. The faster access to satellite data is one of the main advantages of the new satellite system, in addition to the independence of ground stations from other continents.

The space company Tesat-Spacecom was responsible for the development and production of the Laser Communication Terminal (LCT). This highly complex terminal, which now looks back on 20 years of continuous development and consists of more than 7,500 individual parts, is the heart of datalink technology between satellites and allows a data transmission rate of up to 1.8 gigabits per second over a distance of 45,000 kilometers.

In addition to the LCT, the high-tech company from Backnang was also responsible for the Hybrid Relay Payload EDRS-A, including system design, manufacturing and procurement as well as system tests. For this purpose, modulators, TWTAs and filters from Tesat were installed. Other components were also used, which were procured in advance by the internal Parts Agency.

About Tesat: Over the course of five decades, Tesat-Spacecom has developed in-depth expertise in manufacturing of payload equipment for communication satellites and has established itself as a clear European market leader. On its 60,000m² premises in Backnang, Germany, 1,200 employees develop, assemble, integrate, and test systems and equipment for telecommunication via satellite. To date, more than 700 space projects have been completed. The accumulated in orbit lifetime heritage exceeds 250 million hours.
