Solar AIS Net Position Indicator:
The "Intelligent Positioning Guardian" for Marine Operations

In marine fisheries, aquaculture, and related operations, the positioning management and safety protection of fishing nets and other fishing gear have always been core concerns for practitioners. Traditional positioning equipment either has limited battery life or insufficient signal coverage, making it difficult to meet the long-term use needs in complex marine environments. The emergence of the Solar AIS Net Position Indicator (Solar AIS Net Positioning Device) deeply integrates solar power supply technology, AIS (Automatic Identification System) communication technology, and precise positioning functions, becoming an "intelligent guardian" to solve positioning problems in marine operations and bringing revolutionary efficiency improvements and safety guarantees to marine production operations.

I. What is a Solar AIS Net Position Indicator?

A Solar AIS Net Position Indicator, also known as a solar AIS net positioning device, is an intelligent terminal equipment specially designed for the positioning management of marine fishing gear. It uses solar energy as the core energy source, integrates an AIS data transmission module and a high-precision positioning module, and can real-time collect the position information of fishing nets and other fishing gear (such as longitude, latitude, course, and speed). It broadcasts the data to surrounding ships or background management systems through AIS frequency bands, realizing the full-process visual monitoring and safety early warning of fishing gear positions.

Compared with traditional net position indicators, its biggest breakthrough lies in the introduction of AIS technology - an internationally universal system originally used for ship collision avoidance. This allows the signal of the net position indicator to be received not only by fishing boats but also by all ships equipped with AIS receivers, fundamentally solving the limitation that "fishing net positions are only visible to fishermen" and greatly reducing the risk of fishing gear being hit or lost.

II. Core Advantages: Four Major Features Empowering Marine Operations

1. Solar Battery Life, Say Goodbye to "Power Anxiety"

The equipment is equipped with a high-efficiency monocrystalline silicon solar panel and a large-capacity lithium battery (such as Tesla-equivalent lithium battery). In sunny conditions, it can achieve a battery life of "charging for 1 day and using for 3 days". Even in continuous rainy weather, it can still maintain stable operation for several weeks with its ultra-low power consumption design (standby current less than 1mA). There is no need to frequently replace batteries or charge, completely getting rid of the dependence of traditional equipment on external power sources, which is especially suitable for long-term marine operation scenarios.

2. AIS Dual-Mode Communication, Stable Signal and Wide Coverage

Adopting AIS Class A/B dual-mode transmission technology, the transmission power can reach 7W, and the communication distance covers 8-12 nautical miles. The signal can penetrate complex marine environments (such as wind waves and fog). The equipment can not only send precise positions to fishing boat terminals but also be identified by all AIS ships such as passing merchant ships and law enforcement ships. The AIS display screen in the ship's cab will directly display the position mark and warning information of the net position indicator, effectively avoiding collision accidents and reducing fishing gear damage and fuel consumption.

3. High-Precision Positioning, Dynamic Trajectory Traceable

It has a built-in high-precision GPS/Beidou dual-mode positioning module and is equipped with a Kalman filter algorithm to optimize COG (Course Over Ground) and SOG (Speed Over Ground) data. The positioning error is less than 10 meters, and the position is stable without jitter. The background management system can real-time receive the trajectory data uploaded by the equipment. Fishermen can check the real-time flow status of the fishing net through the mobile APP or computer terminal, accurately grasp the dynamics of the fishing gear, and avoid the risk of "losing the net".

4. IP68 Level Sealing, Fearless of Harsh Environments

The shell is made of UV-resistant PC material, whose strength is far greater than that of traditional ABS plastic, and it has excellent heat resistance, salt and alkali resistance, and anti-aging performance. The equipment adopts an integrated sealing design as a whole, with a waterproof level of IP68, which can be immersed in water at a depth of 1.5 meters for several hours without water ingress. Even in extreme weather such as typhoons and heavy rains, it can still maintain stable operation and adapt to the harsh environments of various marine operations.

IV. Application Scenarios: Multi-Field Coverage from Fisheries to Monitoring

1. Marine Fishing: Precise Net Management, Improve Efficiency

In trawling, purse seining and other fishing operations, fishermen can fix the Solar AIS Net Position Indicator on the front end of the fishing net or the buoy to real-time monitor the diffusion range, towing trajectory and depth of the fishing net. When the fishing net deviates from the preset area or drifts due to water flow, the equipment will automatically send an alarm message to avoid the fishing net being entangled with reefs or lost. At the same time, the AIS signal allows surrounding ships to avoid in advance, reducing fishing gear damage and catch loss caused by fishing net collisions.

2. Marine Aquaculture: Fence Positioning, Ensure Safety

In cage culture, raft culture and other scenarios, the net position indicator can be used to mark the boundary of the aquaculture area. By arranging multiple devices around the aquaculture fence to form an "electronic fence", the background system can real-time monitor whether the fence is displaced or damaged. Once a typhoon or other disasters cause the fence to drift, the equipment will send a position early warning at the first time, helping farmers take timely remedial measures and reducing the risk of aquaculture organisms escaping.

3. Marine Monitoring: Dynamic Tracking, Assist Scientific Research

In the fields of marine ecological monitoring and hydrological survey, the Solar AIS Net Position Indicator can be used as a mobile monitoring node, equipped with sensors such as water temperature and salinity. While tracking its own position, it can real-time upload marine environmental data. Its long battery life and resistance to harsh environments enable it to work for a long time in the open sea and unmanned areas, providing continuous and stable monitoring data support for scientific research institutions.
