Arctic sensor networks

Connecting the Unreachable

Data home from the most remote places, over one radio network with one shared uplink.

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

01
A node goes on each station
One battery-powered radio on the mast you already have. No infrastructure needed.
02
The nodes form one self-healing network
If one node drops out, the others route around it. Built so no data is lost.
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.
04
One uplink carries it home
One connection for the whole site. A quiet station shows up in the data.

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
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
- Remote infrastructurePower lines, pipelines and dams far from a mobile network.
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.

The software

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

Working tool

Mesh planner

Plan every node and link on real terrain before anyone flies out. Results are modelled, not measured.

In development

NUNA Console

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

Where we are

The first tests passed, and the field comes next.

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
