Advanced Visual Docking Guidance System / A-VDGS (RLG Docking Systems, distributed by Vardhman Airport Solutions) vs PAPI & Airfield Photometric Calibration System — mobile (Unika / PAC, distributed by Vardhman Airport Solutions)
Spec comparison for two products on Aviation Souk. Both compete in Runway Lighting & Airfield Electrical.
A 3D laser-scanning docking guidance system from RLG Docking Systems (Taiwan) that tracks incoming aircraft nose position in real time and displays stopping and azimuth guidance to the flight deck — eliminating the weight and height variables that defeat simpler optical systems.
A paired photometric calibration solution — vehicle-mounted mobile runway/taxiway light measurement and tripod-based PAPI angle calibration — enabling airfield maintenance teams to verify ICAO and FAA photometric compliance on the airfield without the airport closing.
