Product Overview
YJUAV RNOTE 3 Ultra supports the centimeter-level positioning module of DroneCAN protocol, and supports RTK mobile station and base station functions.
The combination of the two modules can support the dual-antenna heading function, which can be applied to plane, copter, rover and other vehicles.
Product Features
- Multi-band RTK with fast convergence times and reliable performance;
- Concurrent reception of all constellations at same time (GPS, Galileo, GLONASS, BeiDou);
- Using CAN interface, DroneCAN/UAVCAN communication protocol, strong real-time performance, stable communication;
- Dual-antenna heading can be realized to replace the electronic compass heading, and the heading data is more stable and reliable;
- The hard real-time operating system ThreadX is applied, which is safe and reliable;
- Fully compatible with open source flight controller Ardupilot/PX4;
