The US Space Force has awarded a multi-year contract for the development of an advanced encryption system designed to protect satellite communications from cyber threats. Under the agreement, Viasat will develop technology that secures data transmissions between orbiting satellites and ground stations.
At the core of the project is a cryptographic solution engineered to ensure secure communications throughout a satellite’s lifecycle—from pre-launch to active orbit. The initiative falls under the US Space Force’s Space Systems Command and is being executed through Viasat’s Defense and Advanced Technologies division, according to the press release.
A key element of the system is Viasat’s End Cryptographic Unit (ECU), which is being adapted for space environments. The ECU is designed to counter a range of potential cyber intrusions, while maintaining efficiency in size, weight, and power—critical factors for spaceborne equipment.
In addition to space-qualified encryption hardware, the effort includes integration with existing certified ground systems to facilitate rigorous testing and evaluation. This will ensure the encryption technology performs under operational conditions and supports mission-critical data protection.
As part of the contract, Viasat will also provide enhanced Ground Operating Equipment. This upgraded platform is built to manage increasingly complex encryption protocols and key management systems, helping to secure data from interception or disruption during transmission.
The encryption architecture aims to address both current and emerging threats in satellite communications, with a focus on modularity and scalability to support future upgrades. It also supports the broader goals of strengthening the resilience and cybersecurity of US space assets.
By enabling more secure links between space and ground, the technology contributes to ongoing efforts to bolster national defense capabilities in the rapidly evolving domain of space operations.
While the company remains involved in delivery and support, the emphasis of the program is firmly on enabling secure and reliable satellite communication in contested digital environments.
