    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...

  • 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.
LCT135 in test bench

As the worlds’ only serial manufacturer of in-orbit certificated and tested laser communication terminals, Tesat is chasing its own records. Now another LCT135 terminal has been produced, tested and qualified in record time and is ready for delivery.

Backnang, 21.11.2018: Sentinel-1C will be ESA’s 8th satellite of its Copernicus program. Despite monitoring arctic sea-ice, mapping and surveilling marine environment, Sentinel-1C will support in monitoring and mapping land-surface as well as forest, water and soil and support humanitarian aid in crisis situations. As well as its predecessors, Sentinel 1A&B and 2A&B, it will also be equipped with a standard LCT135 from Tesat for low-earth-orbit (LEO) purposes. The now manufactured, tested und qualified LCT is a rebuild of the already in-action terminal onboard the other Sentinels and is expected to be launched in the first quarter of 2020.

"Even though Tesat has already produced and put into operation more than ten terminals, it is always a special moment, when a new LCT is thrusted into its test bench and put through its paces”, so Matthias Motzigemba, Head of Sales Communication Systems at Tesat. “Being the worlds’ only serial manufacturer of space-certified laser communications technology can be easing, but is also challenging to prove again and again that you are capable to surpass yourself.”

Following this approach, Tesat will be the first company to launch the lightest ever Direct-to-Earth (DTE) laser terminal at the beginning of 2019. Doing so on their own Cube Satellite, the so-called CubeLCT shows dimensions of only 10 x 10 centimeters while weighing less than 400 gram; thus the terminal is capable of bringing LEO to ground communications to a whole new level and speed. Another noteworthy achievement of the German company is to empower the International Space Station with a high-speed data connection through its other DTE terminal T-OSIRIS.

Not only enabling high-speed data transfer between satellites, Tesat is also engaged in developing optical ground stations together with its long-term cooperation partner DLR (German Aerospace Center), with which they have also developed both Direct-to-Earth terminals. Therefore, downlinks from heights of up to 36,000 kilometers down to Earth are possible and can thus – putting on higher data throughput and therefore lower need for data storage – enrich existing solutions and satellite systems with new possibilities and applications.

“Tesat is well prepared for the future with its vast portfolio in laser communications. We can offer solutions for geostationary to low-earth orbit, from satellite constellations to cube satellites, optical ground stations and even for the ISS. As the only company worldwide with such a differentiated and in fact space-tested portfolio we are the one-stop-shop for space based laser communications”, concludes Motzigemba.
