Satellite communications have traditionally been associated with a particular type of environment: remote, difficult to reach, and far beyond terrestrial infrastructure. At sea, in isolated regions, or during operations where local infrastructure cannot be relied upon, satcom is indispensable.

But the assets that need satellite connectivity do not necessarily spend all their time in those environments. A government vehicle can move from a city into a remote area. A logistics fleet can travel through strong cellular coverage before crossing hundreds of kilometres with very little. A critical asset might normally have excellent terrestrial connectivity, but still need to remain online when that infrastructure is unavailable.

Satcom does not need to be the default to be critical

Cellular remains extremely well suited to connected assets operating within terrestrial coverage. Multiple cellular networks can provide strong performance across much of an asset's journey, making it unnecessary to route everything through satellite simply because satcom is available.

The importance of satcom becomes clear at the edges of that infrastructure. When cellular networks become weak, congested or disappear entirely, satellite provides a connectivity path independent of local terrestrial coverage. This means that it is a necessary layer not only when a critical asset is on the move, but also when it is static and cannot go offline even when there is a temporary issue with the local cellular network.

For mobile and mission-critical applications, that additional path changes what is possible. The asset does not need to be permanently remote for satcom to be valuable. It simply needs to operate somewhere, at some point, where losing connectivity is not an acceptable option.

The missing layer is orchestration

Stellar offers resilient connectivity across networks by orchestrating multiple communication technologies into a single, continuous internet connection. Instead of treating satellite and cellular as separate connectivity systems, our software brings them together and manages how they are used.

The technology aggregates available connectivity and seamlessly switch traffic between cellular, satcom and other ip-based links. STEER® operates at ip packet level, allowing connectivity to adapt dynamically as network conditions change.

That means an asset travelling through strong cellular coverage can make use of terrestrial networks. As those networks degrade, traffic can be managed across the connectivity paths still available. When terrestrial connectivity can no longer provide what the application requires, satcom is there to maintain the connection.

The application does not need to make that decision. The connectivity layer does.

What this changes for connected operations

Bringing cellular and satcom into one orchestrated environment creates practical advantages:

  • Satcom where it matters: satellite can provide connectivity beyond terrestrial coverage without becoming the permanent default.
  • Continuous mobility: assets can move between very different communications environments while remaining online.
  • Resilience: critical operations gain connectivity paths that do not all depend on the same terrestrial infrastructure.
  • Interoperability: commercial, terrestrial and non-terrestrial connectivity can be integrated into a common architecture.
  • Flexibility: organisations can introduce new connectivity capabilities without rebuilding the applications that depend on them.

Powered by Stellar: making different networks work as one

As governments, defence organisations and industry increase their use of satcom, including sovereign and commercial capabilities, having access to more communications networks is only the beginning. Those networks also need to work together.

Stellar provides that orchestration layer. We are not a satellite provider or a telecom operator. Our role is to bridge different connectivity technologies so that cellular and satcom can each be used where they are most relevant.

Satellite takes connectivity beyond the limits of terrestrial infrastructure. Orchestration makes that capability part of one resilient connection.

And for assets that cannot afford to go offline, that is when satcom becomes truly powerful.

About Stellar

Stellar’s mission is to bring resilient connectivity across networks to mobility, enterprise, and governments, by combining the very best of terrestrial and satellite networks into one unbreakable connectivity solution.

Stellar Telecommunications SAS ("Stellar"), was founded in 2021 as a truly European company: headquartered in Bordeaux, France, it also runs critical activities from Luxembourg via its subsidiary Stellar Telecommunications Sarl.
