M2 Pro/M2 Pro Max Cerulean USBL ROV Locator Mark II - Autosync

Chasing Cerulean USBL ROV Locator Mark II - Autosync

Simply power up, start the dive and track the ROV location in real-time on the QGroundControl map display. Serial communication and API are available.

Autosync works by exposing the Receiver and Transmitter to GPS or GNSS signals at the start of the mission and optionally at intervals during the mission. Satellite acquisition occurs typically within 30 seconds of power-up. In the canonical case of a ROVL receiver sited near the ROV operator and a ROVL transmitter on the ROV, the satellite acquisition will typically occur in the background, and at the time the ROV is being readied for launch and while the ROVL Receiver IMU calibration is being done.

The ROV Locator Mark II includes a transmitter mounted on the ROV and a receiver module located on the surface. The bundle also comes with a mounting ring and adapter. Simply power up, start the dive and track the ROV location in real-time on the QGroundControl map display. Serial communication and API are available.

There are several optimizations made to this USBL system, addressing configuration and synchronization. However, it is important to note that in real-world usage, the positioning accuracy of the USBL system can be influenced by various factors such as environmental conditions, operational scenarios, and signal interference.

The positional error range for horizontal ROV positioning is approximately 0-8.5 meters when the distance between the receiver and transmitter is 50 meters (this is caused by changes in receiver attitude and orientation), and the offset distance increases as the distance between the receiver and transmitter increases.

To enhance the practical accuracy of the USBL system, we recommend fixing the USBL receiver to prevent it from rotating due to fluctuations in seawater. Additionally, it is advised to maintain a reasonable distance between the USBL receiver and the pool wall or vessel to avoid interference.
