--- title: "NUNA: Connecting the Unreachable" description: "NUNA connects remote sensors through a self-healing radio mesh, so a whole Arctic field site shares one uplink instead of a satellite link at every station." url: https://nunasystems.com/ --- ![Radio masts and small equipment huts on a snow-covered mountain shoulder under a deep blue sky](https://nunasystems.com/assets/img/rf-mountain-masts-hero.jpg) Arctic sensor networks # Connecting the Unreachable Data home from the most remote places, over one radio network with one shared uplink. [Tell us about your site](https://nunasystems.com/contact) [See how it works](https://howitworks.nunasystems.com/) - DTU X-Tech 2026 winner - ![PSV, PreSeed Ventures](https://nunasystems.com/assets/credentials/psv.svg) Advancement Award - DTU Skylab Incubator [Follow the build on LinkedIn](https://www.linkedin.com/company/nunasystems) What we do ## A terrestrial network for sites with no infrastructure. Data blind spots between visits, and an energy-inefficient terminal at every station. We replace both with one telecommunication network, designed and tested for the Arctic. [The full technology, with every detail](https://howitworks.nunasystems.com/) 1. ![A grey NUNA node clamped to a mast beside a weather sensor, on a rocky headland above the sea](https://nunasystems.com/assets/img/node-coast-mast.jpg) 01 ### A node goes on each station One battery-powered radio on the mast you already have. No infrastructure needed. 2. ![A grey weatherproof enclosure with the NUNA wordmark and an upright antenna, on a plain light background](https://nunasystems.com/assets/img/node-studio.jpg) 02 ### The nodes form one self-healing network If one node drops out, the others route around it. Built so no data is lost. 3. ![A logger box, a small solar panel and a GNSS antenna on an instrument pole against a pale sky](https://nunasystems.com/assets/img/rf-solar-logger-pole.jpg) 03 ### Each node sends in its own time slot A shared schedule tells every node when to send. In between, it stays in deep sleep. 4. ![A small stone equipment hut with a lattice radio mast, satellite dishes and a bank of solar panels on a dry hilltop](https://nunasystems.com/assets/img/rf-relay-station-solar.jpg) 04 ### One uplink carries it home One connection for the whole site. A quiet station shows up in the data.

In a climate chamber at DTU tested down to minus 40 degrees Celsius LoRa packets sent at -40°C, acknowledged by the receiver over 98 percent of about 19,600 LoRa radio packets sent at minus 40 degrees Celsius were acknowledged by the receiver Area one network is designed to cover target about 31,000 square kilometres, a V2 design target Next is the V2 node in a weatherproof casing, then our first field deployment in summer 2027. ![A valley glacier flowing between bare grey mountains into a meltwater lake, under a clear sky](https://nunasystems.com/assets/img/rf-glacier-panorama.jpg) Built at DTU ## Four of us, at DTU Skylab in Lyngby.
