Αριάδνη / ARIADNI   NAVIGATION & GUIDANCE KIT for UAVs and DRONES without GPS


Unmanned Aircraft (UAVs fixed wing) as well as Drones and Multicopters are designed to rely 100% on GPS position location.

There exist cases where a particular mission (attack, reconnaisance, monitoring) may be compromised by adverse factors such as GPS denial, GPS jamming, spoofing or no coverage by any GPS system at all.

ARIADNI is a retrofit kit which ensures continuation of mission using autonomous navigation and guidance even under reduced position accuracy. As soon as normal GPS operation resumes the air vehicle on board flight system automatically relies on GPS correction.
