Tesat’s optical terminals recently passed interoperability tests with other laser communication terminals. This is a critical step in their deployment. Their SCOTT80 optical terminal was chosen by Lockheed Martin who is building satellites for the SDA’s envisioned mesh network of interconnected satellites. The SDA, a division within the U.S. Space Force, intends to form a comprehensive network where satellites share data, especially from a tracking layer responsible for detecting missiles. The optical terminals’ primary function is to enable data transmission between these satellites through laser connectivity in space. Adherence to the technical specifications and standards set by the SDA, along with interoperability with terminals from other suppliers like Mynaric and CACI, has been a key focus of the testing process.

While the advancements in laser communication technology for space applications show promise in enhancing data transfer efficiency between satellites, it’s important to recognize the cybersecurity risks associated with such systems. Optical communication, although offering high-speed data transfer, could potentially be vulnerable to interception or hacking. Safeguarding these communications against cyber threats is critical to ensure the integrity and security of the transmitted data.

Tesat’s achievement in developing interoperable and compliant optical terminals is a significant step forward but it’s also crucial to address and fortify the cybersecurity measures associated with optical communication systems in space. Safeguarding against potential cyber threats is essential to maintain the confidentiality and reliability of the data being transmitted among interconnected satellites.
