Product Description
Product Overview – D3-H RTK Heading Positioning Module
The VK-FLY D3-H is a professional dual-antenna RTK heading positioning module independently developed by VK-FLY (Weike UAV Tech). It integrates multi-system GNSS receiver and real-time attitude heading calculation algorithm, designed to solve low-precision yaw and heading drift issues of single-antenna GNSS modules on industrial UAVs.
Fully plug-and-play compatible with VK-FLY V10-PRO industrial flight controller, D3-H outputs centimeter-level horizontal positioning data and accurate aircraft heading angle synchronously. It supports fixed base station RTK and mobile dynamic takeoff & landing modes, perfectly matching VTOL fixed-wing drones, heavy-lift multirotor, aerial survey UAVs and large agricultural plant protection drones.
The module adopts integrated heat dissipation shell with IP65 dustproof and splash-proof grade. It runs stably under ambient temperatures ranging from 30°C to 34°C, adapting to high-temperature farmland, open-air survey sites and outdoor inspection scenarios without positioning failure or data delay.
