From solo hikes to multi-device expeditions, Azimuth gives you the tools to navigate confidently and stay in touch with your group — no signal required.
LoRa radio reaches up to 10km line-of-sight with no phone signal, no internet, no infrastructure. Here's how we envision groups staying connected — some scenarios are tested, others are on our roadmap.
Azimuth runs on off-the-shelf hardware. No custom PCB, no waiting list — buy a board, flash the firmware, you're tracking in minutes.
Flash firmware →OEO stands for One Ear Open — a philosophy: staying attuned, present and aware of your surroundings, even when the world is imperfect. It's about listening to what matters, tuning out the noise, and moving through the landscape with intention.
Azimuth started as a project to solve a real problem — keeping track of a group during long trail runs without relying on mobile signal. It's grown into a GPS tracker with a companion web app, LoRa peer sharing, and more features in active development.
Early development: Azimuth works, but it hasn't been battle-tested at scale. We're building in the open, iterating quickly, and we know there's more to do. If you're interested in trying it — especially for organised events — we'd love your feedback. Get in touch →
