Finnish weather technology startup Skyfora has secured €6.5 million in fresh funding to accelerate the rollout of a unique atmospheric monitoring platform that transforms existing GNSS infrastructure into a large scale real time weather sensing network.
The investment comes as weather forecasting enters a new era driven by artificial intelligence, where the quality of forecasts increasingly depends on the volume and accuracy of environmental data available to predictive models. Skyfora believes it can solve one of the industry’s biggest challenges by turning already deployed GNSS receivers into a global source of atmospheric observations.
GNSS Signals Become Weather Sensors
Rather than building expensive networks of weather stations, radar installations, or balloon launches, Skyfora uses a different approach.
As GNSS signals travel from satellites to receivers on the ground, they pass through layers of the atmosphere containing varying amounts of water vapor. These atmospheric conditions slightly delay the signals. By measuring those delays across thousands of receivers and satellites, Skyfora can calculate humidity levels and generate highly detailed three dimensional maps of atmospheric moisture.
Because water vapor plays a critical role in cloud formation, rainfall, and storm development, this information becomes a valuable input for modern forecasting systems.
The concept, known as GNSS meteorology, has existed in scientific research for years, but Skyfora is attempting to commercialize the technology at a much larger scale.
Telecom Networks Provide Global Coverage
One of the company’s biggest advantages is its ability to use infrastructure that already exists.
Telecommunications operators deploy GNSS receivers throughout their networks for timing and synchronization purposes. Skyfora’s software can extract atmospheric information from those receivers without requiring operators to install entirely new weather monitoring equipment.
In locations where telecom GNSS infrastructure is unavailable, the company supplements coverage with its own StreamGNSS hardware.
This significantly lowers deployment costs while allowing the system to scale rapidly across large geographic areas.
AI Forecasting Drives Demand
The rapid development of AI weather models has exposed a major weakness in modern forecasting systems: insufficient observational data.
Many forecasting improvements now depend less on computational power and more on obtaining dense, high quality atmospheric measurements. Large portions of the world’s atmosphere remain poorly observed, especially outside major developed regions.
Skyfora’s technology is designed to fill those gaps by continuously generating real time atmospheric observations that can be fed directly into forecasting models, risk management platforms, energy systems, agriculture operations, transportation networks, and climate monitoring tools.
Expansion Across Multiple Regions
The new funding will support the commercial expansion of Skyfora’s software platform, weather intelligence products, and atmospheric data services.
The company is already operating deployments in several countries and is pursuing additional opportunities across Europe, the United States, Africa, and the Middle East.
Investors participating in the round include Eviny Ventures, Ugly Duckling Ventures, Lumo Labs, the European Innovation Council Fund, while additional support came from Business Finland.
GNSS Is Becoming More Than Positioning
What makes Skyfora particularly interesting is how it highlights the growing role of GNSS technology beyond navigation and positioning.
For decades, GNSS has been associated primarily with mapping, surveying, transportation, and precision agriculture. Today, companies are increasingly using satellite signals to measure atmospheric conditions, detect interference, monitor infrastructure, and support advanced AI applications.
Skyfora’s approach could become one of the most efficient examples of this trend. Instead of building a dedicated weather sensor network from scratch, the company is leveraging infrastructure that already exists and extracting entirely new value from it.
If the model scales successfully, it could provide meteorological organizations and AI forecasting companies with access to significantly denser atmospheric datasets at a fraction of the cost of traditional observation networks.
