Ace Breaking News – From the report: Satellites are the primary backups to undersea cables, but their bandwidth is far behind physical connections.

Tom’s Hardware reports that NATO is developing an advanced system to address the growing number of undersea cable disruptions observed in recent years.

Known as HEIST (Hybrid Space-Submarine Architecture Ensuring Infosec of Telecommunications), the project is designed to significantly enhance the resilience of undersea communication networks. HEIST will enable damage detection with an accuracy of one meter, facilitate rapid data rerouting through satellite networks when disruptions occur, and establish open-source protocols to foster global collaboration.

For example, Google’s latest fiber-optic lines can hit 340 terabits per second. In contrast, the frequency used by most satellites — 12 to 18GHz — can only handle about 5 gigabits per second or about 0.0015% of the maximum throughput of Google’s fiber connection.

Work is underway to upgrade satellites from radio transmissions to lasers, increasing the speed by about 40 times to 200 Gbps. Starlink already uses this technology to communicate between its satellites, while Amazon is also developing it for its own Project Kuiper. However, it still faces challenges, like poor visibility and targeting precision between the satellite and ground station. Because this is a major NATO project, the alliance plans to open-source part of the process.

Making it public would allow anyone interested to find holes and make many iterations. Gregory Falco, the NATO Country Director for HEIST, believes that this is the fastest way for the project to achieve its goals and help prevent any catastrophic loss of data transmission in case of deliberate attacks against these underwater infrastructures in international waters.
