  • 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...
  • 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 –...
Mous 3

Sometimes it goes haywire at Tesat - for our TWTAs and MPMs there is only one direction: UP! And this in the truest sense of the word, because most (though not all) of our devices climb to about 36,000 km.

Such a satellite start is something special and always interesting to see, even if it is quite quickly over. Here I can especially recommend the starts of ARIANE. In the Internet, not only the start is shown live, but also all sorts of interesting facts about the satellites and their construction are told. With some luck you can sometimes even see some of our amplifiers. The launches take place mostly at night, but if you do not want to stay up, you can watch the clip the next day - but then the tension is gone because you know how it went.

In 2015 a lot of our devices have already been shot into the sky.

  • 1502xx idrss01/20/2015: Start of 601AG, third flight set. We built the seven SINGLE MPMs in 2010 and since then they were obviously stood on the floor quite long. Photo 1 is an unusual long exposure of the launch, where even the starry sky (or dust in the lens?) can be seen.
  • 01/02/2015: Start of INMARSAT 5, second sentence flight. With 42 DUAL MPMs a real hunk - all in Ka-band.
  • 02/03/2015: Start of ABS3A with SATMEX-7. Overall, even more devices, namely 54 DUAL MPMs.
  • 03/19/2015: Start of EXPRESS AM7, built for Airbus. There were 42 DUAL MPMs and three SINGLE L-band MPMs on it.
  • 03/27/2015: Start of Galileo, flight sets 7 and 8, for SSTL (12 SINGLE MPMs in total).
  • 03/28/2015: Start of IRNSS 1D - the fourth satellite for an Indian Navigation System. Six SINGLE MPMs are there on board. Photo 2 shows a dramatic photo of the launch.
  • 04/29/2015: Start of THOR 7 for SSL (and Norway) with 11 DUAL and five SINGLE TWTAs.
  • 05/16/2015: Large bust! The first MEXSAT satellite with six SINGLE MPMs crashed at startup. An error in the third stage of the Proton launcher led to failure.
  • 05/27/2015: Therefore here are two satellites launched by one Ariane: namely DTV 15 for Airbus with 75 DUAL MPMs (an almost incredible amount of equipment. The satellite was formally peppered with MPMs, on every corner watching the collectors of TWTs out!) and DTH 1 for orbital with 32 SINGLE MPMs.
  • 07/16/2015: The Ariane 5 brings Star One C4 with 64 SINGLE MPMs / TWTAs on board into space.

So til middle of July we brought 353 MPMs and TWTAs into orbit in 2015. Now they just have to work another 15 years without interference.
