SEAGULL-GPK 2 CAMERA TRIGGERS - Precision Dual-Band RTK GNSS Receiver and Geotagging Module for Survey Drones

The SEAGULL-GPK 2 CAMERA TRIGGERS module is the ultimate hardware positioning powerhouse engineered for professional UAV pilots who require flawless post-processed (PPK) or real-time (RTK) surveying results.

Sub-Centimeter Dual-Band RTK Precision :

Moving far beyond standard single-band positioning systems, the #GPK2 utilizes dual-band architecture to track L1 and L2 satellite signals simultaneously. This cuts down convergence initialization times to seconds and locks down an incredible 1-centimeter accuracy threshold, providing robust location stability even in difficult, high-vibration commercial flight conditions.

Advanced Camera Shutter Event Syncing :

Eliminate timing delays and coordinate mismatch issues completely. The module features an integrated internal hardware interrupt loop connected straight to its onboard EVENT pin. By capturing the exact millisecond your mapping camera's hotshoe flashes or triggers, it records a precise coordinates stamp instantly, ensuring absolute alignment between individual photo frames and flight track logs.

High Refresh Rate Performance Hub :

To support fast-moving fixed-wing mapping platforms and close-quarter multirotor sweeps, the board scales its data tracking output significantly. It comfortably delivers up to 25Hz in PVT and RTK modes, 15Hz in PPK raw data extraction, and 10Hz in Moving Baseline configurations, providing smooth tracking fidelity at high flight speeds.

Flexible Base and Rover Multi-Modes :

Designed to integrate seamlessly into diverse ground configurations, a single #GPK2 hardware block can be programmed effortlessly as either the airborne ROVER payload or the stationary BASE station anchor, giving you full control over specialized Real-Time Kinematic, Moving Baseline, and Post-Processed Kinematic operations.

Frequently Asked Questions :

Q1: What makes the SEAGULL-GPK 2 significantly better than the original GPK module?

Ans: The #GPK2 upgrades the baseline to a dual-band u-blox ZED-F9P core receiver, lifting refresh rates up to 25Hz and achieving a tight 1cm RTK positioning threshold, compared to the older single-band receiver architecture.

Q2: How does the internal event logging loop handle geotagging workflows?

Ans: The hardware EVENT pin listens for direct feedback from your camera's hotshoe adapter. The moment the exposure finishes, the exact spatial coordinates match onto the 16GB storage log automatically, simplifying downstream processing in Pix4D or Agisoft.

Q3: Can I run this system directly from my flight controller's telemetry rail?

Ans: Yes, the module draws an average of 140mA at 5V, making it highly safe to power directly from standard Pixhawk or Cube telemetry/GPS ports without creating heavy power draw concerns.

Q4: Does the SEAGULL-GPK 2 bundle package include an antenna?

Ans: Yes, every official kit comes fully loaded with 1x Seagull #GPK2 core module, 1x high-quality dual-band GNSS antenna featuring an extended 5-meter low-loss connection cable, and a 16GB MicroSD storage card with a full-size adapter.
