The Operating System for Space

The leading solution for autonomous, dynamic management of next generation satellites and SATCOM networks.

Industry Leading, Award Winning

With our customers and partners, we're spearheading the transformation of SATCOM

Why Kythera?

We make the SATCOM Operating System that manages your satellite payload, coordinates it with the rest of your in-orbit and ground-based assets, and autonomously optimizes your entire fleet to best serve you and your customers. With Kythera, you can provision and manage satellite service dynamically, improve quality of service, and lower your cost per useful bit. All autonomously.


Kythera’s intelligent, real-time systems make it easy to harness the full power of your most advanced high-throughput satellites, enabling you to maximize capacity and service.


The Kythera OS plans and re-plans, configuring and reconfiguring your satellite and ground components, minute-by-minute.


The Kythera OS provisions satellite service automatically and makes ongoing autonomous decisions necessary to preserve each user’s signal.


The Kythera OS anticipates and automatically compensates for risks and threats to satellite communications service, including weather, hardware failure, and interference.


We integrate with your payload control software, gateways, modem platforms, terminals, and enterprise systems for fully orchestrated SATCOM service.


Increase your satellite, fleet, and constellation capacity by optimizing power, bandwidth, coverage, frequency, beam shape and laydown, and routing plans. With Kythera, you deliver service and capacity exactly where and when it’s needed.

I’m proud to have Kythera teaming with us to deliver our Space Inspire Ground mission segment. We consider Kythera's expertise as unique: Managing and optimizing software-defined satellites and SATCOM networks. Their groundbreaking Kythera Operating System (KOS) sets the gold standard and offers our customers the easiest way to take advantage of an SDS satellite."
