Raytheon Technologies [RTX] this week said it has formed a strategic partnership with SpiderOak, a provider of cybersecurity solutions for space systems, to develop and field new zero-trust systems for satellite communications in proliferated low-Earth orbit (pLEO).

Raytheon’s BBN business unit will bring its distributed, disrupted, disconnected and denied secure cloud solution and SpiderOak its OrbitSecure solution to offer customers resilient mesh networks in contested environments.

Raytheon said the combined solution can be applied across multi-vendor constellations.

“This partnership is paving the way toward secure, on-demand, geostationary equatorial orbit network-like pLEO communications,” Jason Redi, president of Raytheon BBN, said in a statement. “Raytheon’s networking technology ensures that the satellite constellation provides the best routing solution during normal operation, while also dynamically supporting autonomous cross-link routing during disrupted environments. SpiderOak’s technology allows us to maintain distributed secure operations with high efficiency, particularly when the constellation is reconfigured and paths are not preplanned.”
