    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...

  • 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.
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.

"When we introduced our groundbreaking technology exactly one decade ago, the goal was to transfer even the largest amounts of data between satellites in orbit and to establish the safest and fastest transmission," explains Matthias Motzigemba, Sales Communication Systems at Tesat-Spacecom.

The LCT135 from Tesat is based on homodyne binary phase shift keying and features bidirectional backbone technology and coherent detection. The terminal has a power consumption of 150 W and offers a very efficient solution for the long-distance transmission of data. The dimensions of the terminal are 60x60x70 cm with a weight of 53 kg. The LCT135 is in TRL9 (Technology Readiness Level) and has been produced 16 times.

"Currently, our laser technology is used every day for the transfer of important time-critical earth observation data which can be used for monitoring of our oceans, early warning of natural disasters and in support of other emergency services," said Motzigemba. The LCTs are mainly deployed on Sentinel satellites of the European Copernicus program or on geostationary satellites within the Airbus powered SpaceDataHighway.

LCT135 © Tesat-SpacecomSuitable solutions for Direct-to-Earth market
Tesat-Spacecom is also developing very compact laser modules for Direct-to-Earth applications – called CubeL and TOSIRIS.

The CubeL has a power consumption of 8 W with a weight of 360 g. The module offers a data transfer rate of 100 Mbps. The TOSIRIS transmits 10 Gbps from smaller satellites to the ground. It has a power consumption of 40 W and weighs 8 kg. A special feature of these LCTs is the standard according to the CCSDS (Consultative Committee for Space Data Systems). Both modules send data over a distance of up to 1,500 km.

High security transmission
The data connection will be aborted If disturbed by another object. So, above all, Laser Communication Terminals by Tesat-Spacecom offer a more efficient and much safer technology than conventional radio frequency technology. The transmission by LCTs is able to support encryption via quantum key distribution method.
