CHASING-INNOVATION CHASING M2 PRO/M2 PRO MAX CERULEAN USBL ROV LOCATOR MARK II - AUTOSYNC 40.30.400.0883

Chasing Cerulean USBL ROV Locator Mark II - Autosync

Power up, start your dive, and track the ROVs location in real-time on the QGroundControl map. The system features serial communication and an API.

Autosync Functionality

Autosync utilizes GPS or GNSS signals at the missions start and optionally during the dive. Satellite acquisition typically occurs within 30 seconds of powering up. The ROVL receiver, positioned near the operator, and the transmitter on the ROV allow for background satellite acquisition while preparing for launch and during IMU calibration.

System Components

The ROV Locator Mark II includes:

• Transmitter mounted on the ROV
• Receiver module on the surface
• Mounting ring and adapter

Performance Considerations

While several optimizations enhance the USBL system, real-world positioning accuracy can be affected by environmental conditions and signal interference. The horizontal positional error is approximately 0-8.5 meters at a 50-meter distance between the receiver and transmitter, with increased error at greater distances.

Recommendations for Accuracy

To improve accuracy, secure the USBL receiver to prevent rotation from seawater fluctuations and maintain a reasonable distance from pool walls or vessels to minimize interference.

Software Updates

Ensure you upgrade to the latest versions of the APP, ROV, and Dock Firmware:

1. Fixed issues in APP version 4.9.9
2. New USBL Trajectory Recording and Import
3. New USBL Interest Point Marking & Split-Screen Map/Video Display
4. Automatic storage of water quality sensor data to ROV memory card
5. Two new ROV operating modes
6. New control method for mechanical arm/water quality sampler
7. Manual configuration mode for accessory dock
