UM220-IV

The UM220-IV is a compact, high-performance GNSS module from Unicore Communications, supporting multi-constellation reception (GPS, GLONASS, Galileo, BeiDou). It features RTK (Real-Time Kinematic) for centimeter-level accuracy, making it ideal for precision applications like drones, surveying, and autonomous vehicles.
Key features:
- Multi-frequency (L1/L2/L5) for improved signal reliability.
- High update rate (up to 20Hz) for dynamic environments.
- Low power consumption (~1.5W) and small form factor.
- Supports external IMU integration for enhanced navigation.
Ideal for mapping, agriculture, and robotics, the UM220-IV balances accuracy, speed, and power efficiency.
