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.

The development of the CubeLCT serves the demand for increasing bandwidth resulting of new sensor capabilities on small satellites, which is facing bottleneck issues with today commonly used radio frequency technology. In the future, small satellites will benefit of the ultra-lightweight laser terminal with a mass less than 400 gram and a volume of only about one third U (9,5 x 9,5 x 3,25 cm³), which is capable of data rates of up to 100 Megabit per second.

Furthermore, due to physical properties of a laser beam, the technology is unaffected by ITU regulations and independent of frequency bands while enabling enhanced security aspects: Optical links are interference-free and resilient to eavesdropping by technology and are the medium for quantum key distribution (QKD) technology.

The CubeLCT was developed in cooperation with the Institute of Communications and Navigation of the German Aerospace Center (DLR-IKN) and is based on a long-time industrial heritage.
