Overview

The TOXU KS.WA.0076 is a compact dual-band RTK GNSS receiver designed for UAVs, drones, robotics, autonomous vehicles and other precision navigation systems.

The receiver is based on the u-blox ZED-F9P RTK GNSS module and supports GPS, GLONASS, Galileo, BeiDou and QZSS satellite navigation systems across L1 and L2 GNSS bands.

When valid RTK correction data, suitable satellite visibility and correct system configuration are available, the KS.WA.0076 supports horizontal and vertical RTK positioning accuracy of 0.01 m + 1 ppm.

Without RTK correction data, the product operates as a standard GNSS receiver with specified autonomous positioning accuracy of 1.5 m CEP.

The KS.WA.0076 integrates a QMC5883P electronic compass to provide magnetic heading information. USB Type-C, dual UART, TTL and I²C interfaces support connection to compatible flight controllers, embedded computers, telemetry equipment and robotic control systems.

The receiver electronics are installed inside a compact 38 × 28 × 12.1 mm CNC aluminum housing, providing a practical integration solution for systems requiring a protected ZED-F9P receiver instead of a bare module or open receiver board.

The u-blox ZED-F9P platform can support moving-baseline heading when two compatible receivers and two GNSS antennas are correctly configured as a base and rover pair.

USB Type-C Interface

The USB Type-C interface supports receiver configuration, data communication and connection to compatible computers and host systems.

Dual UART Communication

Dual UART interfaces provide flexible data input and output for flight controllers, correction links and embedded navigation systems.

TTL and I²C Connectivity

TTL and I²C interfaces provide additional integration options for compatible embedded hardware.

UBX, NMEA and RTCM Protocol Support

Supports UBX configuration and navigation messages, NMEA data output and RTCM correction-data communication.

Up to 10 Hz Navigation Update

Supports a maximum navigation update rate of 10 Hz for dynamic positioning applications.

1PPS Timing Output

Provides specified 1PPS timing performance of 30 ns RMS and 60 ns at 99 percent.

Compact CNC Aluminum Housing

Applications

UAV and Drone Navigation

Provides centimeter-level RTK position data for compatible multirotor, fixed-wing and other unmanned aerial platforms.

Pixhawk and PX4-Based Systems

Supports integration with compatible Pixhawk flight controllers and PX4-based autopilot systems through the available communication interfaces.

Robotics

Provides precise outdoor positioning for autonomous robots and unmanned ground vehicles.

Autonomous Vehicles

Can be connected to compatible vehicle controllers and embedded navigation computers requiring RTK GNSS data.

RTK Base and Rover Systems

Supports customized base-station and rover configurations when combined with suitable antennas, correction links and system software.

Moving-Baseline Heading Systems

Two compatible receivers can be configured with two GNSS antennas to provide moving-baseline position and heading information.

Industrial Precision Navigation

Suitable for embedded navigation and positioning equipment requiring a compact protected RTK receiver.

System Integration

The KS.WA.0076 receives multi-constellation GNSS signals through an external compatible dual-band antenna and outputs position data through USB or UART communication.

A typical RTK rover connection is:

Dual-Band GNSS Antenna → KS.WA.0076 Receiver → USB/UART → Flight Controller or Embedded Computer → Navigation System

RTK correction data may be delivered through a compatible base station, NTRIP service, telemetry radio or host controller.

A typical correction-data path is:

RTK Base Station or NTRIP Service → Data Link → KS.WA.0076 → RTK Position Output

For moving-baseline GNSS heading, two compatible receivers and two antennas are required:

Primary Antenna + Primary Receiver ↔ Secondary Antenna + Secondary Receiver → Moving-Baseline Position and Heading Output

The built-in QMC5883P compass provides magnetic heading information independently of the paired moving-baseline GNSS heading solution.

Before installation, customers should confirm the antenna type, connector, interface pinout, voltage level, baud rate, output protocol, correction-data source and flight-controller configuration.
