Equipped with a u-blox ZED-F9P multi-band (L1/L2) high-precision GNSS receiver and status LEDs, this unit provides reliable centimeter-level correction data for RTK rover systems. It supports standard RTK base features such as survey-in and fixed-position modes, enabling stable and repeatable reference positioning. Ideal for UAV operations, ground robotics, mapping workflows, and any system requiring a dependable RTK correction source over radio, telemetry, or NTRIP. Can be used as an RTK Fixed Base, Moving Base, or Rover.
Key Highlights
-
GNSS receiver: u-blox ZED-F9P multi-band (L1/L2) GNSS delivering centimeter-level accuracy in seconds, concurrent GPS/GLONASS/Galileo/BeiDou reception, fast multi-band RTK convergence, high update rates for dynamic applications, energy-efficient operation, and support for moving-base RTK heading.
-
Antenna: High-performance helical GNSS antenna (dual/tri-band) connected via a standard SMA connector. Supports direct attachment of antennas up to 27.5 mm diameter; larger or external antennas may be connected using an SMA extension cable.
- RF front end: Uses the integrated u-blox ZED-F9P RF architecture, featuring built-in low-noise amplification, filtering, and advanced multi-band signal processing for robust RTK performance.
- Open-source and flexible: Runs ArduPilot-compatible DroneCAN peripheral firmware for plug-and-play operation with Pixhawk and other DroneCAN-enabled flight controllers.
-
USB-C port: Provides direct access to u-center for configuration, data logging, and firmware updates.
- Standard connectors: Pixhawk Standard UART (4-pin JST-GH), Pixhawk Standard Debug (6-pin JST-SH), and USB-C.
