In an uncertain world, we believe in certainty. Communication certainty. Anywhere, at any time and in any situation. We don’t just believe it’s possible, we’ve built the satellite network that uniquely makes it so.

World leading reliability

When your mission depends on an absolute trust in your communications link, you can rely on us. We alone combine inter-networked, overlapping satellite constellations with secure satellite access stations, paired redundancy and automatic back up switching to deliver the world’s most reliable global satellite communications network – unmatched at 99.9%.

Built to move

Unconstrained mobility is critical for government operations. Unlike others, our satellite network responds in real time, requiring no advanced planning to move across the globe. Communicate on the move or on the pause with no prior notice. All made possible by our uniquely designed multi-satellite, multi-band service, all within a single network. Delivering a seamless communications network for your operational teams and the ultimate in borderless flexibility.

Built to fit

When you need something to meet your specific mission requirements, turn to us. We own our satellite network and ground stations, giving our global team of engineers the capability to build bespoke solutions others simply can’t.

First for innovation

Getting ahead and staying there are two different things. That’s why we invest more than $600M a year to stay at the forefront of technology. We built the world’s first satellite network for global mobility, and the first worldwide network offering Safety of Life at Sea. Up next? The first network to provide user terminal visibility of multiple satellites from any given location. Discover our future-proof solutions that governments depend on.
