UAV Navigation-Grupo Oesía Unveils GNSS-Denied Navigation Kit, a Significant Leap Forward in Autonomous Navigation for Dead Reckoning Environments

  • This new product enhances the dead reckoning navigation capabilities of UAS, reducing drift to minimum values and making it resistant to jamming or spoofing attacks.


Madrid, 13 February, 2024. – UAV Navigation-Grupo Oesía, the leading innovator in navigation solutions, is proud to unveil its latest product, the GNSS-Denied Navigation Kit. This revolutionary solution is specifically designed to thrive in GNSS-denied environments, offering unparalleled navigation capabilities in challenging scenarios.

The new GNSS-Denied Navigation Kit combines the precision and reliability of UAV Navigation-Grupo Oesía's Attitude and Heading Reference System (AHRS), the POLAR-300, with the state-of-the-art Visual Navigation System, the VNS01. This powerful integration ensures unmatched dead reckoning navigation capabilities with minimal drift, setting new standards for precision and stability in challenging scenarios.

Some of the key features of the GNSS-Denied Navigation Kit include:

  • Exceptional field-proven navigational accuracy: The product provides highly accurate GNSS-denied navigation, maintaining error rates as low as 0-1% over covered distances.
  • Visual-based technology for precise attitude and position estimation: UAV Navigation-Grupo Oesía's focus on innovation is evident in the GNSS-Denied Navigation Kit, surpassing traditional techniques and offering a groundbreaking solution with visual navigation for precise and stable flights in challenging conditions.
  • Proven against counter-UAV/anti-UAV measures: Equipped with state-of-the-art algorithms, the kit can detect and counter sophisticated 'spoofing' y ‘jamming’ techniques, ensuring reliable and secure navigation even in the face of potential disruptions.


As technology advances and geopolitical challenges emerge, the demand for reliable and secure navigation for Unmanned Aerial Systems (UAS) intensifies. Ensuring operational integrity in both civil and defense sectors is paramount, especially with the rise of disruptive systems designed to interfere with radio-electronic navigation and communication.

The GNSS-Denied Navigation Kit addresses these challenges head-on, offering a robust solution that combines different technologies. Immune to external disruptions, this kit represents the future of autonomous navigation. With GNSS signals increasingly under threat from both unintentional and intentional interference, the shortcomings of traditional navigational systems are evident.

"At UAV Navigation-Grupo Oesía, we understand the current and future demands of clients inside the unmanned aviation sector. The GNSS-Denied Navigation Kit is a testament to our dedication to providing innovative solutions that enable our customers to operate in challenging scenarios where the GNSS signal is not available," said Miguel Ángel de Frutos, Director and CTO at UAV Navigation-Grupo Oesía.
