Uninterrupted Navigation Under Jamming Conditions

GöRDES Vision-Based Navigation Product provides accurate and real-time position, velocity and attitude information for aerial vehicles under GNSS denied conditions via onboard imaging and image processing.

GöRDES Vision-Based Navigation System provides accurate and real time position, velocity and attitude information for aerial vehicles under GNSS denied conditions via onboard imaging and image processing.

For almost every vehicle requiring outdoor navigation, GNSS is mostly regarded as the only system that can generate accurate position information. However, GNSS signals are widely subject to jamming and spoofing under operational conditions. To mitigate this vulnerability, alternative ways of navigation are needed. Thanks to advances in image processing, photogrammetry, and computer vision, studies on image-based navigation systems have come to the fore as complementary systems.

By using image processing and computer vision algorithms, GöRDES provides position, velocity, and attitude information by matching the previously captured onboard satellite/aerial images with the images taken from the GöRDES camera system of the aerial platform. Besides, it implements a Visual Odometer for accurate velocity estimation of the air platform. GöRDES enables air vehicles to complete their mission and safely return home.

Capabilities:

3D position, velocity, and attitude data under GNSS jamming
Alarm generation under spoofing conditions

Passive system (No active emission, cannot be blocked or interfered with)
Low Size, Weight, and Power (SWaP) requirements

Advantages

GöRDES is designed to operate in difficult geographical and weather conditions. The system can be integrated into a variety of platforms, from mini-UAVs to manned aircraft. The widespread use of UAVs in military and civilian operations and the same increased rate of jamming/spoofing systems made GöRDES a necessity.
