ESEN GöRDES™ Vision Based Navigation (VBN) System Demonstrated High Performance on UAS Flight Tests
Ankara, Türkiye – ESEN has successfully demonstrated GöRDES™ Vision Based Navigation (VBN) system with flights on NATO Class III-MALE to Class I-Mini unmanned aerial vehicles, in an altitude range from 1000 feet to 15.000 feet AGL. NATO Class III tests were performed with Turkish Aerospace on ANKA MALE UAS. GöRDES™, which can be integrated into various platforms, from Mini unmanned aerial vehicles (600 kg), has proved its capability to provide accurate navigation data under GNSS-denied environments.GöRDES™ is specifically developed to provide a solution for GNSS Jamming and Spoofing. As the conflicts around the world increase, GNSS jamming is more frequently used to prevent rival UAS flights. Furthermore, GNSS jamming is also becoming more and more a problem even for civilian users of GNSS. UASs that are subject to jamming, generally depend on inertial navigation methods, but inertial navigation systems drift, due to their nature. In such circumstances, GöRDES will be an effective tool to continue safe flight.
About GöRDESESEN started developing indigenous VBN technology back in 2018. GöRDES™ produces accurate and real time position, velocity, and attitude information for aerial vehicles under GNSS denied conditions via onboard imaging and real time image processing techniques, mitigates GNSS vulnerability, enabling aerial vehicles to safely navigate in GNSS-denied environments.As of today, ESEN GöRDES™ has been tested on platforms ranging from NATO Class III-MALE to Class I-Mini UASs, from 1000 feet to 15.000 feet AGL altitudes. Tests not only included different altitudes but also different seasons, times of the day, illumination conditions, different geographies like mountainous regions, forests, steppes, semi-cloudy and foggy times etc. The tests have shown that, mean absolute error (MAE) of 19m (horizontal) and 4 m (vertical) at 10.000 ft AGL, 23 m (horizontal) and 5 m (vertical) at 15.000 ft AGL and down to 5m (horizontal) and 1 m (vertical) at 1000 ft AGL flights for the real-time estimated position are achieved. The tests have been concluded for the daytime version. Night-time version is under development.For more information, visit https://www.esensi.com.tr/product/gordes
