What we do

A terrestrial network for sites with no infrastructure.

The full technology, with every detail

01
A node logs the data
A battery-powered logger that connects directly to your sensor, on the infrastructure you already own.
02
Nodes form a resilient network
Intelligent routing and backup storage on every node are designed so no data is lost, even in the roughest conditions.
03
A custom protocol ensures power is used efficiently
The protocol keeps each node sleeping 99% of the time, extending battery life.
04
One uplink for the whole network
All data gathered in one uplink. Easily accessible from your home.

Use cases

Who we help, and what changes for them

Our focus now
Environmental monitoring
Who
Polar institutes and research field stations
Pain
A sensor fails in October and nobody knows until summer
Solution
Every station reports all season, through one uplink
The use cases
- Glacier and ice sheet monitoringWeather masts and GNSS stations across the ice, on one network.
- Permafrost monitoringGround temperature through the season, not once a year.
- Seismic and geodetic stationsKnow every station is alive and recording.
Where we are heading
Assets and critical infrastructure
Who
Operators of power lines, pipelines and dams
Pain
Assets far from a mobile network are checked by visit
Solution
Sensors along the route relay to one uplink, with no coverage needed
The use cases
- Power linesTilt, icing and line temperature along spans far from a mobile network.
- PipelinesStrain, pressure and ground movement between inspection trips.
- Dams and reservoirsWater level and seepage from dams with no coverage nearby.
Where we are heading
Satellite Earth observation
Who
Teams who calibrate and validate satellite data
Pain
Ground truth is hardest to get where it matters most
Solution
A grid of ground sensors, on one clock, home through one uplink
The use cases
- Ground truth for satellitesMeasurements on the ground to check what orbit sees.
- Snow and ice productsSnow depth and surface temperature across a satellite footprint.
- Soil moisture productsSoil moisture at many points inside a single satellite pixel.

The software

Plan the site on real terrain. Watch it from one screen.

Working tool

Mesh planner

Plan and simulate every node and link on real terrain before anything is installed.

In development

NUNA Console

Every node and field team on one screen, with an alert when something goes quiet.

Test results

We tested our first boards in a climate chamber at DTU. These are the results.

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
Crystal clock stability, measured in the chamber: crystal clock held to 0.03 parts per million

The next version, v0.2, is in its enclosure and running on DTU campus now, and v0.3 is on the way. The first field deployment is in Denmark in winter 2026, then Greenland in summer 2027.
