Whether you are mapping, surveying, or performing industrial inspections, your drone needs precise navigation data to perform at its best. That’s where the Seagull #GPK module comes into play. Designed for professional and hobbyist drone builders alike, the Seagull #GPK is a high-performance GNSS (Global Navigation Satellite System)receiver that provides fast, accurate, and dependable positioning data for UAV applications. that provides fast, accurate, and dependable positioning data for UAV applications.

In this blog, we’ll explore what makes the Seagull #GPK stand out, how it works, its features, setup process, and why it’s becoming a favorite choice among drone enthusiasts and professionals worldwide.

The Seagull #GPK is a compact and high-precisionGNSS receiver module specifically built for UAV and aerial photography applications. It uses multi-constellation satellite tracking, including GPS, GLONASS, Galileo, and BeiDou, to provide accurate positional data., including GPS, GLONASS, Galileo, and BeiDou, to provide accurate positional data.

Unlike basic GPS modules, the #GPK offers RTK (Real-Time Kinematic) compatibility, which allows centimeter-level positioning accuracy — a must for mapping, surveying, and autonomous flight operations., which allows centimeter-level positioning accuracy — a must for mapping, surveying, and autonomous flight operations.

Its compact size, lightweight build, and robust design make it ideal for integration into almost any drone system, whether it’s a fixed-wing, multirotor, or hybrid UAV.

• • RTK and Standard GNSS Modes: The Seagull #GPK supports both standard GNSS operation and RTK mode for extreme precision. In RTK mode, it can achieve accuracy within a few centimeters — perfect for professional surveying and mapping missions.
  • Multi-Constellation Support: It tracks signals from multiple satellite systems — GPS (USA), GLONASS (Russia), Galileo (EU), and BeiDou (China). This ensures better coverage, faster lock times, and improved accuracy even in challenging environments.
  • Plug-and-Play Compatibility: One of the biggest advantages of the #GPK is its simple installation process. It connects easily to popular flight controllers such as Pixhawk, Cube, and Ardupilot-based systems without complicated setup.
  • High Refresh Rate: With update rates up to 10Hz or higher, it delivers real-time position data with minimal delay — crucial for precise drone control during dynamic flights.
  • Compact and Durable Design: The #GPK is built with a durable yet lightweight housing that can withstand outdoor environments. Its small size allows easy mounting even on small drone frames.
  • Low Power Consumption: Designed with efficiency in mind, the #GPK uses minimal power, making it perfect for long flight durations without draining the drone’s battery.

  • Data Logging and Timestamping: The module can record flight data and provide accurate timestamps for aerial photography — an essential feature for photogrammetry and post-processing accuracy.

The Seagull #GPK works by receiving satellite signals from multiple constellations and calculating the drone’s precise location, altitude, and speed. When operating in RTK mode, it pairs with a base station or correction network that sends real-time correction data, improving accuracy from meters to centimeters.

This capability is extremely valuable in surveying, mapping, and agriculture, where even small positional errors can lead to large measurement inaccuracies.

• Mount the Antenna: Secure the GNSS antenna on the drone’s top frame for the best sky visibility. Avoid metal interference or propellers blocking its line of sight.
• Connect to the Flight Controller: Use the provided cable to connect the #GPK to the GPS port of your flight controller (Pixhawk, Cube, etc.).
• Configure in Software: Open the configuration software (like Mission Planner or QGroundControl). Select the appropriate port and set the baud rate as per Seagull’s documentation.
• Enable RTK (Optional): If you’re using an RTK base station, configure the correction data source. Once connected, your #GPK will display centimeter-level accuracy.
• Test the Connection: Once setup is complete, check the GPS status. You should see a stable lock with multiple satellites and low positional error.

• Aerial Mapping and Surveying: With RTK precision, the #GPK ensures every image and data point is accurately geotagged — reducing post-processing errors.
• Precision Agriculture: It helps drones follow exact flight paths for spraying or monitoring, ensuring efficient coverage and minimal overlap.
• Search and Rescue Operations: The reliable positioning allows rescue drones to navigate difficult terrains with accuracy, even under challenging GPS conditions.
• Cinematography and Photography: For aerial filmmakers, the #GPK ensures smoother camera positioning and precise location data for each frame.
• Inspection and Monitoring: In industrial inspections, it ensures drones maintain precise positions when scanning towers, pipelines, or solar farms.

The Seagull #GPK stands as one of the most efficient and precise GNSS solutions for UAV users today. It bridges the gap between hobby-grade GPS modules and high-end RTK systems by offering reliability, speed, and accuracy in one compact package.

For drone builders, surveyors, and professional operators, integrating the #GPK into their setup means better navigation, smoother flights, and highly accurate mission data. As UAV technology continues to advance, tools like the Seagull #GPK will remain essential for unlocking the full potential of aerial operations.
