PERSEUS: What it Does and Does Not Do
The Origin of PERSEUS
Technology is only as useful as the conditions in which it can operate. For teams working in remote, austere, or disaster-affected environments, reliable connectivity can be difficult to guarantee.
Developing ATLAS, Certus Innovations’ IoT-powered asset tracking solution, highlighted an important limitation of global cellular connectivity: it works wherever the necessary infrastructure is available, but not everywhere missions need to go.
For operations such as delivering humanitarian supplies to rural Ethiopia, supporting disaster recovery in Puerto Rico after Hurricane Maria, or transporting cargo to Alaska’s Aleutian Islands, reliable connectivity cannot always be assumed. These environments underscore the need for communication solutions that can operate without relying on existing civilian infrastructure.
At the same time, existing tactical mesh networking solutions can be prohibitively expensive. PERSEUS emerged from the opportunity to make infrastructure-independent communications more accessible and practical for teams operating in challenging environments.
Built to Stay Connected: Mesh Networking
PERSEUS uses mesh networking technology through Meshtastic, allowing compatible, configured devices to communicate with one another and relay messages across a network. Rather than relying entirely on a central connection, each participating device can help pass information to other nodes, extending the network's reach.
Consider a traditional cellular network: your phone relies on cell towers to connect with other devices. In a mesh network, a message can travel from one device to another through intermediate nodes until it reaches its destination, without requiring every device to connect directly to a cell tower.
For PERSEUS, this distributed approach offers a practical advantage: if a node goes offline, messages can often travel through another available route, provided a viable path remains between the sender and recipient. The network can also be extended by strategically placing additional nodes to help expand coverage into areas where traditional infrastructure is unavailable or impractical.
The result is a flexible communications network designed to adapt to changing conditions, extend its reach, and maintain connectivity when individual nodes become unavailable.
Why LoRa: Range Without the Infrastructure
At the heart of Certus Innovations’ PERSEUS system is LoRa, a communication technology selected for its ability to support long-range connectivity while consuming very little power. This is a valuable combination in tactical environments and disaster recovery scenarios where reliable infrastructure cannot be taken for granted. With LoRa, one can deploy their team, sensors, and trackers, with far less concern for range or battery life.
LoRa differs from cellular transmission as the infrastructure is fundamentally different. While cellular infrastructure uses substantially more transmission power to achieve its coverage, LoRa is designed to communicate over long distances while consuming far less power.
However, this efficiency comes with tradeoffs. LoRa prioritizes range and power consumption over bandwidth, making it well suited for text and short status/sensor updates, rather than high-volume data or real-time voice communications. When a mission requires richer communication capabilities, technologies such as TAK TALK can help address those needs.
Built for Reach, Honest About Limits
PERSEUS isn’t designed to do everything, and that’s the point. By pairing Meshtastic mesh networking with long-range, low-power LoRa, it gives teams a practical way to exchange text and short status or sensor updates where cellular coverage isn’t available and tactical alternatives are out of reach on cost. It won’t carry real-time voice or high-volume data, and its reach depends on having a viable path between nodes. When a mission needs richer communication, tools like TAK TALK can fill that gap. Knowing where a technology fits, and where it doesn’t, is what makes it dependable in the field. For teams heading beyond the edge of the network, PERSEUS offers a simple, affordable way to stay in touch.
