Overview

The TOXU TX-G5-RTK01 is an ultra-light RTK GNSS receiver kit built around the Septentrio mosaic-G5 high-precision positioning platform. It combines a multi-frequency GNSS receiver, an RM3100 magnetometer, an external active quadrifilar helix antenna and Pixhawk-compatible connection hardware.

The receiver supports concurrent tracking of GPS, GLONASS, Galileo, BeiDou and QZSS signals. When supplied with compatible RTCM correction data, it provides centimeter-level RTK positioning for UAVs, robotics and mobile autonomous systems.

Septentrio GNSS+ technologies—including AIM+, IONO+, APME+, LOCK+ and RAIM+—improve receiver reliability in environments affected by RF interference, ionospheric disturbances, multipath, mechanical vibration and signal-integrity risks.

The integrated RM3100 magnetometer provides magnetic heading information to compatible navigation systems. The magnetometer is not an IMU, and the TX-G5-RTK01 must not be described as a GNSS/INS receiver.

The standard kit includes one TX-G5-RTK01 receiver, one L1/L2/L5 active quadrifilar helix antenna, one Pixhawk-compatible JST-GH cable, one mounting structure and one antenna extender.

Key Features

Septentrio mosaic-G5 GNSS Platform

Built around the Septentrio mosaic-G5 platform with 789 hardware channels for simultaneous tracking of supported GNSS signals.

Multi-Constellation GNSS Tracking

Supports GPS, GLONASS, Galileo, BeiDou and QZSS for reliable positioning across different operating regions.

Multi-Frequency Signal Reception

Tracks multiple signals across the L1, L2 and L5 frequency ranges ranges, improving availability, RTK initialization and positioning reliability.

Centimeter-Level RTK Positioning

Supports horizontal RTK accuracy of 0.6 cm + 0.5 ppm and vertical RTK accuracy of 1 cm + 1 ppm when compatible correction data and suitable operating conditions are available.

Fast RTK Initialization

Provides a specified RTK initialization time of approximately 7 seconds under suitable satellite visibility and correction-data conditions.

RM3100 Magnetometer

Integrates a professional RM3100 magneto-inductive magnetometer for magnetic heading measurement in UAV and robotic navigation systems.

AIM+ Interference Protection

Provides monitoring and mitigation functions for GNSS jamming, spoofing and radio-frequency interference.

IONO+ Ionospheric Protection

Improves positioning robustness in the presence of ionospheric disturbances affecting GNSS signals.

APME+ Multipath Mitigation

Uses advanced multipath estimation to reduce the influence of code and carrier-phase multipath errors.

LOCK+ Tracking Robustness

Maintains stable signal tracking under mechanical shock and vibration conditions found in UAV and mobile robotic platforms.

RAIM+ Integrity Monitoring

Provides advanced receiver autonomous integrity monitoring for improved positioning-data reliability.

Active Quadrifilar Helix Antenna

Includes one compact L1/L2/L5 multi-band active quadrifilar helix antenna for space- and weight-sensitive installations.

Integrated Status Indicators

Provides RTK, TIME and PWR indicators for quick operating-status diagnostics.

PX4 and ArduPilot Support

Designed for integration with compatible Pixhawk flight controllers running supported PX4 or ArduPilot firmware.

Technical Specifications

* QZSS L6 and related Galileo HAS functionality depend on the applicable Septentrio software and firmware release.

Applications

• High-precision UAV navigation

• Pixhawk-based autonomous aircraft

• UAV mapping and photogrammetry

• Precision agriculture drones

• Mobile robotics

• Autonomous navigation systems

• Industrial inspection platforms

• High-dynamic GNSS positioning

• Research and development projects

System Integration

The TX-G5-RTK01 is supplied as an assembled receiver kit for integration with compatible UAV flight controllers, robotic controllers and embedded navigation systems.

The JST-GH 6-pin connection cable supports integration with compatible Pixhawk hardware. The exact connector pin definition, voltage, serial settings and flight controller configuration must be verified before connection.

USB Type-C can be used for receiver configuration, monitoring and data communication. The receiver also provides UART, PPS, event and GPIO resources through the mosaic-G5 hardware platform.

Centimeter-level RTK operation requires correction data from a compatible GNSS base station, CORS network or NTRIP service. Accuracy and initialization performance depend on satellite visibility, antenna placement, baseline length, correction quality and operating environment.

The supplied quadrifilar helix antenna should be mounted with a clear view of the sky and separated from high-power transmitters, motors and other potential interference sources.

The RM3100 is a magnetometer that provides magnetic heading information. It does not include a gyroscope or accelerometer and does not make the TX-G5-RTK01 an INS receiver.

This standard kit contains one GNSS antenna. It is therefore a single-antenna positioning kit and must not be described as a dual-antenna GNSS heading receiver.
