Detection of derelict fishing gear

This invention describes a system to help fishermen find their gear if it gets tangled underwater. A special buoy attached to the fishing gear has sensors that track its movement and location. By comparing the buoy's current speed and how far it has drifted from where it was first placed, the system can figure out if the gear is likely tangled with marine life and send an alert.

Why it matters: Since 2020, the cost and power efficiency of compact GPS and accelerometer modules, along with low-power satellite or cellular IoT communication, have continued to improve. This makes the long-term deployment of such sensor-equipped buoys more economically viable and extends their operational life in remote marine environments.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateGPS, accelerometer, processing, communication, software logic
