Sat.One launches multi-constellation LEO service

Enterprise low earth orbit (LEO) satellite connectivity provider Sat.One has rolled out a multi-constellation LEO service designed to deliver reliable, high-availability communications across Australia.

The service, Sat.One Resilient, was designed to for enterprise and government and “provides consistent performance across remote and hybrid environments, delivering intelligent link management, always-on multi-constellation connectivity and seamless integration with customer networks”, according to Sat.One CEO Dan Fairbairn.

At the core of Sat.One Resilient is Argo, a software-defined edge platform built specifically for the unique demands of LEO connectivity.

While traditional SD-WAN solutions are designed for stable terrestrial networks and react only after a link degrades, Argo “takes a different approach,” the provider said.

It anticipates changes in link conditions caused by weather, radio frequency interference or satellite movement and adapts in real time to maintain consistent performance across multiple LEO constellations.

“LEO connectivity is redefining what’s possible for enterprise communications … but unlocking its full potential requires more than just access, it demands resilience,” said Fairbairn.

“That’s why we designed and built Sat.One Resilient from the ground up, powered by Argo, to meet performance, availability, and reach.” 

As the adoption of LEO satellite networks accelerates, enterprises increasingly turn to non-terrestrial network connectivity to extend beyond the reach of terrestrial infrastructure.

However, with this opportunity comes new complexity, including maintaining performance across different constellations and minimising the impact of packet loss, jitter and latency on critical applications.

“Sat.One tested multiple SD-WAN products and found none met the performance thresholds needed for enterprise-grade LEO,” said Fairbairn. “Unlike SD-WAN, Argo proactively mitigates link degradation before it impacts the user.”

Sat.One Resilient is designed to work with customer networking environments, including SD-WAN deployments. Argo provides a demarcation point at the customer edge and supports standard Ethernet handoff.

It retains differentiated services code point markings and aligns with the three classes of service offered by OneWeb, enabling more predictable performance for latency-sensitive applications such as VoIP, telemetry, real-time video and remote system control.

The service supports critical infrastructure projects across the government, emergency services and resource sectors.

Sat.One Resilient is available exclusively through Sat.One’s partner network of telecommunications and managed service providers.

It is designed to integrate seamlessly into partner offerings, delivering added resilience for customers in remote locations or those who need alternate network paths to safeguard against terrestrial outages.

Previously, Fairbairn told ARN while it looks forward to working with its telco company partners, it does want resellers to know that it is looking to build up its channel.

“We don’t have a specific number of resellers we want to bring on board,” he said at the time. “We are looking to partner with those who are interested in the regional enterprise space and we are offering traditional wholesale margins.”
