SEAGULL-GPK CAMERA TRIGGERS - High Precision GNSS RTK PPK Aerial Mapping Module for Pixhawk
The SEAGULL-GPK CAMERA TRIGGERS is an industrial-grade, single-band GNSS receiver and event logger engineered for professional UAV photogrammetry and mapping applications.Optimized for centimeter-level accuracy, this high precision GNSS mapping module seamlessly down-converts environmental satellite telemetry into microsecond-accurate photo geotags.Its primary benefit is its versatile capability to process Real-Time Kinematic (RTK), Post-Processed Kinematic (PPK), and Moving Baseline (MB) navigation modes on a compact, ultra-lightweight 16-gram footprint.
The SEAGULL-GPK CAMERA TRIGGERS establishes a new benchmark for high-accuracy surveying payloads, turning standard commercial multirotors into professional-grade geospatial mapping platforms.Powered by a high-performance Ublox NEO-M8P-2 GNSS architecture, this single-band module captures raw carrier phase measurements to deliver down to 2.5 cm position precision.By interfacing directly with camera shutter releases, it logs high-precision shutter events directly against live GNSS coordinates, completely eliminating spatial synchronization errors and vastly reducing post-processing orthophoto stitch times.
Key Features :
Multi-Mode Kinematic Engine:Natively supports BASE/ROVER, RTK, PPK, and Moving Baseline (MB) positioning profiles for versatile field setups.
Microsecond Event Syncing:Features a high-speed hardware input pin dedicated to logging exact camera shutter trigger events in real time.
Massive Onboard Data Vault:Includes an integrated 16GB micro SD card slot to record raw satellite logging files for subsequent PPK processing.
Ultra-Lightweight Profile:Weighs an incredible 16 grams, ensuring zero impact on aircraft center of gravity or overall battery endurance.
Use Cases :
Professional aerial photogrammetry mapping, GIS data indexing, and high-accuracy cadastral surveying.
Precision agricultural crop analysis, forest canopy measurement, and volumetric mining layout inspections.
Dynamic navigation positioning for multirotors operating in challenging, high-vibration environment envelopes.

Compatibility Information :
The Seagull GPK module features seamless plug-and-play telemetry links tailored for mainstream open-source autopilot environments. It is fully compatible with Pixhawk 1, Pixhawk 2.1 Cube, Pixracer, and APM flight controllers executing ArduPilot or PX4 firmware stacks.The command interface integrates flawlessly with camera controllers like Seagull MAP-X2, SYNC2, and standard hot-shoe feedback adapters.
Frequently Ask Questions :
Q1 ) What structural benefits does the integrated 16GB SD card offer during high-speed mapping flights?
Ans : The integrated high-speed 16GB micro SD card acts as a standalone hardware data logger.It continuously records raw satellite observation telemetry (UBX binary formats) completely independent of the main drone telemetry logs, guaranteeing that critical PPK data remains safe even if the drone loses its wireless data link.
Q2 ) Can I run this Seagull GPK hardware module as a fixed ground station instead of an airborne receiver?
Ans : Yes, the system architecture supports dual BASE and ROVER configuration setups. You can easily configure one module as a stationary reference ground station via software parameters, allowing it to broadcast real-time differential RTK correction streams to your second flying Rover module over an external radio link.
Q3 ) Does this camera trigger system package arrive ready to mount with its antenna and connection wiring harnesses?
Ans : The standard retail package contains the core 16g Seagull GPK receiver module, one matched high-gain GNSS antenna, a 16GB micro SD card with its full-size adapter, and product registration document files. Autopilot interface cables (like the custom purple/red Pixhawk link) are supplied separately to match your specific hardware setup.
Q4 ) Is the Seagull-GPK camera trigger system compatible with standard industrial autopilots in India?
Ans : Yes, it is fully optimized for standard industrial flight stacks used across commercial enterprises in India. The receiver communicates natively over standard serial UART links using UBX and NMEA telemetry sentences, dropping directly into Pixhawk, Cube, and ArduPilot processing ecosystems.
Q5 ) How far can this micro receiver module maintain its centimeter-level tracking precision in the field?
Ans : The absolute hardware position measuring envelope handles up to 2.5 cm accuracy in RTK mode relative to its base station location.In PPK post-processing workflows, it tracks carrier phase data continuously across huge flight zones, provided the antenna maintains a clear view of the sky without signal shadows.
