Description

The WTMotion WTRTK-982 RTK GNSS Receiver Module is engineered for applications demanding high-precision geospatial data. Its dual-antenna architecture, powered by the NebulasIV SoC, enables not only centimeter-level Real-Time Kinematic (RTK) positioning but also precise heading calculation, which is critical for orientation-sensitive systems. The module’s Ï€-type impedance-matching network enhances signal acquisition and stability, even in challenging RF environments.

Built for industrial durability, the module operates reliably across an extended temperature range from -40°C to +85°C. Its compact 26mm x 38mm footprint houses advanced anti-interference circuitry and an antenna detection unit, ensuring robust performance in autonomous vehicles, agricultural machinery, and UAVs. The module outputs standard NMEA0183 protocol data via its UART interface, while the integrated USB Type-C port provides convenient power and data connectivity for development and deployment.

Key Features

  • Dual-Antenna RTK Engine: Enables simultaneous centimeter-level positioning and high-accuracy heading determination.
  • Full Multi-GNSS Support: Tracks BDS, GPS, GLONASS, GALILEO, QZSS, and SBAS satellites for maximum coverage and reliability.
  • High-Speed Data Output: Delivers positioning and directional solutions at a 20Hz update rate for real-time control applications.
  • Industrial-Grade Robustness: Features a wide operating temperature range (-40°C to +85°C) and built-in anti-interference design.
  • Integrated Antenna Detection: Circuitry monitors antenna status and connection integrity for system diagnostics.
  • Simplified System Integration: Offers plug-and-play USB Type-C connectivity alongside a standard 6-pin UART interface.
  • Compact Form Factor: A 26mm x 38mm module design optimized for space-constrained embedded systems.

Applications

  • Precision Agriculture: Guidance for autonomous tractors and sprayers for variable-rate application.
  • Unmanned Aerial Vehicles (UAVs): High-accuracy navigation and heading control for mapping and inspection drones.
  • Robotics & Autonomous Mobile Robots (AMRs): Precise localization and orientation for warehouse logistics and service robots.
  • Intelligent Driving & ADAS: Sensor fusion input for vehicle positioning and lane-level navigation systems.
  • Marine & Surveying Equipment: Centimeter-accurate positioning for hydrographic surveys and dynamic positioning.

Frequently Asked Questions

What is the primary advantage of the dual-antenna system in the WTRTK-982?

The dual-antenna system enables the module to calculate not just precise position (centimeter-level RTK), but also accurate heading or orientation. This is achieved by measuring the phase difference of the satellite signals between the two antennas, which is essential for applications like autonomous vehicles, drones, and robotics that need to know which direction they are facing.

What interfaces does this module provide for data output and power?

The module provides two primary interfaces: a 6-pin UART connector for serial communication outputting standard NMEA0183 protocol data, and a USB Type-C port. The USB Type-C port serves as a convenient plug-and-play solution for both power supply (5V) and data communication, simplifying development and integration into prototype systems.

What is the operating voltage and typical power consumption of the WTRTK-982 module?

The module requires a 5V DC power supply. Under typical operating conditions with all GNSS systems active and RTK corrections being processed, it draws approximately 220mA of current. It is important to ensure your power source can provide clean, stable 5V power to maintain optimal performance and accuracy.

Are GNSS antennas included with this module?

No, this listing is for the receiver module only. GNSS antennas are not included. You will need to source compatible active antennas with SMA connectors (or the appropriate connector for your chosen antenna cable) separately. The module features a built-in antenna detection circuit to help diagnose antenna connection issues.

What environments is the WTRTK-982 module suitable for?

The module is built for industrial and outdoor applications, with an operating temperature range of -40°C to +85°C. It incorporates anti-interference design elements, making it suitable for harsh environments such as agricultural machinery, construction sites, and marine applications where electromagnetic noise and wide temperature variations are common.
