Overview

The TOXU TX-G015 is an integrated multi-band RTK GNSS receiver module designed for positioning systems requiring a compact antenna-and-receiver configuration.

Unlike a standalone GNSS antenna, the TX-G015 integrates a four-arm helical GNSS antenna, a ZED-F9P positioning engine, signal-processing circuitry, and digital communication interfaces in one compact housing.

The receiver supports compatible GPS L1/L2, GLONASS G1/G2, BDS B1/B2, Galileo E1/E5b, and QZSS L1/L2 satellite navigation signals. Actual signal availability and operating mode depend on receiver configuration, firmware, antenna environment, and regional satellite visibility.

For standalone positioning, the specified horizontal accuracy is ≤1.5m and vertical accuracy is ≤2.5m under the stated test condition of 1σ and PDOP below 4.

When valid correction data is supplied and an RTK fixed solution is achieved, the specified horizontal RTK accuracy is ±(8 + 10 × D)mm and vertical RTK accuracy is ±(15 + 10 × D)mm, where D represents the baseline distance in kilometers.

The receiver supports NMEA, UBX, and RTCM 3.3 data formats. Available hardware interfaces include three UART ports and one I²C interface through an eight-pin, 1.25mm-pitch locking connector.

The TX-G015 operates from 3.3–3.45V DC and has a specified power consumption of approximately 0.95W. Its Φ47 × 35.9mm housing weighs less than 20g.

This integrated configuration is suitable for UAVs, robotics, mobile mapping equipment, precision positioning terminals, autonomous platforms, and other embedded systems requiring compact multi-band GNSS reception and RTK positioning capability.

Technical Specifications

Dimension Drawing

The standard TX-G015 integrated receiver module measures Φ47 × 35.9mm.

Before sample approval and volume production, confirm the overall diameter, height, mounting structure, cable or connector orientation, installation clearance, eight-pin interface position, and mechanical tolerance against the approved drawing and physical sample.

Applications

• Unmanned Aerial Vehicles

• Autonomous Mobile Robots

• Mobile Mapping Equipment

• Precision Positioning Terminals

• Agricultural Guidance Systems

• Surveying and Mapping Equipment

• Robotic Navigation Systems

• Embedded RTK Positioning Devices

• Vehicle Positioning and Tracking Systems

• Industrial Automation Platforms

System Integration

The TX-G015 integrates both the GNSS antenna and ZED-F9P receiver, so a separate external GNSS antenna is normally not required for the standard configuration.

The module requires a regulated 3.3–3.45V DC power supply. The host system should provide sufficient current capacity, low ripple, correct grounding, and suitable protection against reverse polarity, overvoltage, and electrostatic discharge.

Positioning data and receiver communication are available through three UART interfaces and one I²C interface. The exact pin assignment, voltage level, baud rate, communication configuration, and cable definition must be confirmed using the approved interface document.

For RTK operation, the module must receive valid correction data from an RTK base station, NTRIP service, radio modem, cellular modem, or another compatible correction source.

Support for RTCM 3.3 does not mean that correction data is included with the product. The customer must provide or subscribe to a compatible correction-data source.

The integrated antenna should be installed with a clear view of the sky and away from motors, high-current wiring, switching power supplies, telemetry transmitters, digital clock sources, metal shielding, and other potential sources of interference or signal blockage.

For UAV integration, the module should be mounted where vibration, conductive structures, propeller systems, flight-controller electronics, and high-power radio transmitters have minimal influence on GNSS reception.

Final positioning performance must be verified on the customer’s completed equipment because enclosure materials, installation attitude, electromagnetic interference, ground structure, power quality, correction data, and firmware configuration can affect operating results.

FAQ

Q: Is the TX-G015 only a GNSS antenna?

A: No. It integrates a four-arm helical GNSS antenna and a ZED-F9P multi-band positioning receiver in one compact module.

Q: Which satellite navigation systems does it support?

A: The available specification lists compatible GPS, GLONASS, BDS, Galileo, and QZSS signals.

Q: Does the module support RTK positioning?

A: Yes. It supports RTK positioning when valid compatible correction data is supplied and suitable operating conditions are available.

Q: Does the product include an RTK correction service?

A: No. The customer must provide correction data through a compatible base station, NTRIP service, communication modem, or other correction source.

Q: What positioning protocols are supported?

A: The listed data formats include NMEA, UBX, and RTCM 3.3.

Q: Which hardware interfaces are available?

A: The available specification lists three UART interfaces and one I²C interface through an eight-pin locking connector.

Q: What power supply does the module require?

A: It requires a regulated 3.3–3.45V DC supply and has a specified power consumption of approximately 0.95W.

Q: Is an external GNSS antenna required?

A: The standard TX-G015 configuration already contains an integrated four-arm helical GNSS antenna, so a separate external antenna is normally unnecessary.

Q: Is it suitable for UAV installation?

A: Its compact size, weight below 20g, integrated antenna, and RTK receiver support evaluation in UAV applications. Final performance must be verified on the complete aircraft.

Q: Is the product waterproof?

A: No IP rating is provided in the available specification, so waterproof performance must not currently be claimed.

Q: Is the RTK accuracy guaranteed in every environment?

A: No. RTK performance depends on correction-data quality, baseline distance, satellite visibility, multipath, interference, installation, firmware configuration, and the complete operating environment.
