UAV Navigation-Grupo Oesía and the European Space Agency (ESA) have launched a research initiative to utilize Ka-band signals from low Earth orbit (LEO) communication satellites for drone positioning. This research-stage development seeks to build navigation solutions that operate independently of global navigation satellite systems (GNSS).
Why it matters
By leveraging communication signals, this project aims to provide resilient navigation for drones in GNSS-denied, jammed, or spoofed environments. The initiative aligns with European strategic objectives for technological autonomy and sovereignty.
The system utilizes Ka-band signals from LEO communication constellations as a navigation source. It integrates these observables into an autopilot system using multi-sensor data fusion, which combines LEO data with inertial measurements, air data, and vision-based navigation.
The players
UAV Navigation-Grupo Oesía
A developer of flight control systems and avionics that integrate advanced navigation and multi-sensor fusion for unmanned aerial vehicles.
European Space Agency
The intergovernmental organization dedicated to the exploration of space, currently funding navigation resilience research through its NAVISP program.
CTTC
A research center focused on communication technologies and signal processing systems participating in the consortium.
The details
The navigation architecture extracts position estimates from multibeam electronically steered antennas—advanced antennas that can change the direction of a radio signal without physically moving the hardware. These estimates are then processed through a navigation filter, a mathematical algorithm that combines data from multiple sensors to estimate the true state of the vehicle. This multi-sensor approach ensures robust performance even when traditional satellite navigation is unavailable.

The Tech Race
The initiative sits within the broader race to achieve PNT independence from traditional GNSS, which is highly vulnerable to jamming and spoofing. It builds upon existing efforts in non-GNSS navigation by moving beyond terrestrial beacons to utilize the growing density of LEO communication constellations.
This development is currently in the research phase and will not impact existing commercial drone operations immediately. Future implementation will depend on successful validation in flight-representative environments and the integration of this capability into standard autopilot hardware.
The takeaway
The industry is moving toward multi-modal navigation to hedge against the vulnerability of global satellite signals. Observers should track the results of the upcoming flight-representative environment validation to determine if LEO-based PNT can meet real-time flight safety requirements.
