Tesat-Spacecom's optical laser communication terminals have successfully passed key ground tests required for their installation on Space Development Agency (SDA) satellites. This was announced by the company on October 26.

Tesat's SCOTT80 terminal was selected by Lockheed Martin, one of several manufacturers with a contract to produce satellites for SDA.

SDA, an agency under the jurisdiction of the US Space Force, plans to deploy a network of interconnected satellites. It includes a Transport Layer that will transmit data collected by the missile sensor tracking layer. Each spacecraft is equipped with several laser communication terminals.

Optical terminals use lasers to connect satellites in orbit, allowing data to be transmitted in space.

Tesat terminals will be integrated with Lockheed Martin satellites that will be part of the Tranche 1 SDA Transport Layer, which is scheduled to launch in late 2024. Lockheed Martin also uses CACI optical terminals for Tranche 1 satellites.

All optical terminals installed on SDA satellites must comply with the technical specifications and standards established by the agency. They must also be compatible with terminals manufactured by other vendors.

As part of the ground tests, the Tesat terminal was supposed to establish communication with the reference modem, as well as with the Mynaric and CACI terminals. The Mynaric terminal will be powered by Tranche 1 SDA satellites manufactured by Northrop Grumman.

"This achievement demonstrates that Tesat's terminals meet the technical specifications and standards set by the SDA and are compatible with third - party products," said Thomas Reinartz, CEO of Tesat.

The company also noted that the SCOTT80 optical terminal was selected by Kepler Communications for its commercial constellation in low-Earth orbit.

Tesat-Spacecom, based in Germany, is creating an American subsidiary to support military and commercial programs. The company is an independent subsidiary of Airbus Defense & Space.

Tesat plans to start manufacturing optical terminals in Merritt Island, Florida. To date, there are 46 Tesat terminals in orbit, and another 180 are in production.
