  • Live: Launch of Aeolus

    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...

    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,...
Hispasat in Test-Kammer

With Hispasat 36W-1, 25 years after DFS-Copernicus a German communications satellite launched once again into geostationary orbit. On board: a payload from Tesat-Spacecom.

The SmallGEO platform has been produced by ESA, OHB and the Spanish satellite operator HISPASAT as part of a project to provide the Iberian Peninsula, the Canary Islands and South America with multi-media services. Tesat's share of this was the communication payload as well as a suitable automatic high-frequency measuring station for the complete integration and test phase.

The payload consists of a transparent Ku-band repeater with 24 channels as well as the Ka-band repeater with three channels. In addition there are two Ku-band antennas covering Europe and America, a controllable DRA antenna (Direct Radiating Antenna) and the Ka-band antenna. An OBP (On Board Processor) completes the payload. Special mention should be made of the MPMs, whose saturation output power can be changed via telecommands from ground and thus be adapted to the conditions.

However, it was a long way to go: in August 2012, the empty SmallGEO module from OHB arrived and all the individual devices for Ka- and Ku-band had to be integrated. The active direct radiating array antenna and the three reflector antennas were later mounted to the platform by OHB. Beginning in mid-2013, the intensive system tests started in Backnang and after solving of some technical challenges, the end-to-end test of the complete payload without the antennas could be completed in autumn 2013. At the end of this phase, it was moved to the large EMI chamber for the final EMC test. After the successful completion in December 2013, the repeater module from Tesat was handed over to OHB in due time.

After the mating of the repeater module with the platform, Satellite First Reference Test at OHB and the vibration test at the IABG in Ottobrunn followed. Starting in March 2016, Tesat began the most labor-intensive time with the implementation of the TVAC tests in Ottobrunn. The payload had to be fully tested in full vacuum and CATR. This was the first time that the behavior and the performance of the system could be observed and tested under outer space conditions. For over three months, our AIT colleagues worked at IABG in three-shift operation, producing more than 21,000 PDF test reports during this time with our test system, which were then evaluated by our system engineers on site and in Backnang.

  • In September 2016 after many thousands of individual tests the results were confirmed: "The Tesat Payload successfully passed all environmental tests!"
  • On 29 November 2016, the first SmallGEO satellite from Germany left Munich airport on Board an Antonov in direction of Cayenne/Guyana, from where it was then transported to Kourou to the Center Spatial Guyanais
  • In December 2016, the last and final RF measurements of Tesat following the preparations for the start took place
  • On 28 January 2017 at 02:03 (CET) it was time: Hispasat 36W-1 (HAG1) started with a Soyuz from Kourou into geostationary Orbit
