  • TESAT delivers game changer for SmallSat market

    Today we can announce that we delivered our first CubeLCT to a non-disclosed, US-American customer. The CubeLCT is a small, ultra-lightweight optical data transmitter, which is capable of transferring data with 100 Megabit per second from low Earth orbit satellites directly to ground. For us, this delivery marks the starting point of a new product family focusing on NewSpace applications for small satellites and CubeSats.

  • Parts Agency for ORION's European Service Module

    The European Service Module (ESM) Flight Unit 1, a part of the ORION spacecraft, has successfully been shipped from Germany to the US and is now prepared for its marriage with the NASA crew vehicle to be made ready for the launch at the Kennedy Space Center. Not just being a great success for NASA, ESA and Airbus, but also for the Tesat-Spacecom Parts Agency. As subcontractor of Airbus, TESAT is leading the Coordinated Parts Procurement (CPPA) for the European Service Module, which occupies a...
  • Laser Communications Technology from Tesat setting new records

    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.
  • German space alliance relies on technology from Tesat-Spacecom

    As prime for the scientific-technical payload and responsible for the military repeater, Tesat-Spacecom is responsible for the design, construction and verification of the core elements of the German space mission “Heinrich Hertz”.
  • 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...
Physics Laboratory

LISA Pathfinder, the technology demonstrator of the ESA for the detection of gravitational waves, is now ready for transport to the European spaceport in Kourou, French Guiana. From there it will start in November into space. The 1.9-ton spacecraft, for which Airbus Defence and Space is the prime contractor, will be launched aboard a European Vega rocket.

The LISA Pathfinder project is going to open up unknown observation possibilities for the gravitational universe where new measurement of gravitational waves in space required technologies are tested. These by Albert Einstein predicted waves represent distortions of spacetime curvature and are caused by massive celestial bodies. A better understanding of their tracks will bring scientists new insights about black holes, compact binary stars and other exotic celestial bodies.

LISA Pathfinder is carrying the 150 kg LISA Technology Package (LTP). It consists of a laser interferometer, which heart is a Reference Laser Unit by Tesat-Spacecom. The interferometer measures the changes in distance between two high-precision, each 1.96 kg heavy test masses from a gold-platinum alloy. Once the satellite has reached its orbit around 1.5 million kilometers from Earth the two test masses are unlocked via a mechanism and kept in suspension by means of accurately controllable, weak electrostatic field. In the research phase of the mission, the electrostatic field is then switched to one of the two test masses. The spacecraft follows the test mass, controlled by a high-precision attitude control system (Drag-Free Attitude Control System). Laser interferometer and electrostatic sensors measure the movement of the test mass in the spacecraft to ensure that these are not affected by interference. The interferometer now determines the relative position and orientation of about 40 centimeters apart masses with an accuracy of less than 0.01 nanometers, or less than one millionth of the diameter of a human hair.

LISA Pathfinder paves the way for a future large space observatory that will monitor and measure gravitational waves directly and accurately. These tiny distortions of spacetime require a very sensitive and highly precise measuring technology, their performance can only be tested in space, free from external interference.
