Overview

The TOXU TX-ZZED-F9P is a compact RTK GNSS receiver board developed around the u-blox ZED-F9P multi-band GNSS module. It is designed for OEM integration, secondary development and professional positioning-system applications.

The receiver supports GPS, GLONASS, Galileo, BeiDou and QZSS satellite navigation systems across L1 and L2 GNSS bands.

With valid RTK correction data, suitable satellite visibility, correct antenna installation and proper system configuration, the TX-ZZED-F9P supports positioning accuracy of 0.01 m + 1 ppm CEP in RTK mode.

The 43 × 43 mm receiver board provides two UART interfaces, USB Type-C, SPI, I²C, PPS and TTL-level RTCM connectivity. These interfaces support integration with flight controllers, robotic controllers, embedded computers, data radios and other navigation equipment.

An SMA female connector supports connection to an external active GNSS antenna. The standard configuration shown includes the receiver board, connection cable and an active GNSS antenna with a typical gain of 28 dB.

The TX-ZZED-F9P supports NMEA, UBX and RTCM data formats, making it suitable for UAV navigation, robotic positioning, surveying, mapping and precision agriculture.

Technical Specifications

Applications

UAV Navigation

Provides multi-band RTK GNSS data for compatible UAV flight controllers and autonomous navigation platforms.

Robotics and Autonomous Systems

Supports precise outdoor positioning for robots, unmanned ground vehicles and other autonomous platforms.

Surveying and Mapping

Can be integrated into customized surveying and mapping equipment requiring RTK correction input and centimeter-level positioning.

Precision Agriculture

Suitable for agricultural guidance, machine positioning, field mapping and other GNSS-based precision agriculture systems.

Industrial Positioning

Can be integrated into industrial controllers and positioning terminals through UART, USB, SPI or I²C interfaces.

RTK Base and Rover Development

Supports the development of customized RTK base-station and rover equipment when configured with suitable correction links and system software.

System Integration

The TX-ZZED-F9P can be integrated into an RTK rover system using an external active GNSS antenna and RTCM correction data supplied through a compatible communication link.

A typical receiver connection is:

GNSS Satellites → Active GNSS Antenna → TX-ZZED-F9P Receiver Board → Flight Controller or Embedded Computer → Navigation System

A typical RTK correction-data path is:

RTK Base Station or NTRIP Service → Data Link → TX-ZZED-F9P Receiver Board → RTK Position Output

Correction data may be delivered through a compatible data radio, cellular communication device or host controller. The board supports NMEA, UBX and RTCM data formats for system integration.

Centimeter-level positioning requires valid correction data, suitable satellite visibility, correct antenna installation and appropriate receiver configuration. The receiver board alone does not guarantee centimeter-level accuracy in every operating environment.
