Marine controller
Real-time monitoring of the ship’s location through technical means, so as to achieve remote real-time tracking of production safety and shipment schedule implementation.

Application
The realization of ship real-time monitoring has important commercial value. On the one hand, shipping companies, charter companies and other ship operators can remotely monitor the real-time dynamics of the ship, so as to understand the safety management of the ship and the implementation of the ship schedule.

On the other hand, the port management department can realize all the monitoring of the ships in the port area, so as to better arrange the operation plan and ensure the safety of the port area

type
From a technical point of view, there are three mainstream monitoring methods:

1. Coastal CDMA network monitoring
That is, through the CDMA network of China Telecom (formerly China Unicom) to realize the dynamic monitoring of coastal ships.
This monitoring method requires the ship to install the transmitter, the shore-based installation of receiving equipment, through the CDMA network to achieve the ship dynamic data transmission.
The outstanding disadvantage of this monitoring method is that it can only be used in coastal areas with CDMA signals, so it is suitable for coastal transport vessels.

2. Satellite monitoring
Refers to the transmission of ship position data to the company through shipborne satellite transmitters and receivers.
This method is not restricted by the sea area where the ship is located, and can better achieve all-weather monitoring.
However, the significant disadvantage is that satellite communication is expensive and not suitable for continuous monitoring.

3. Coastal AIS system monitoring
It refers to the signal sent by the onboard AIS system to grasp the dynamic data of the ship in real time.
AIS, which stands for Ship Identification System, is mandatory for any ship over 500 gross tonnage in the world, so the range of ships covered is very wide.

Since the signal transmitted by the AIS system can only cover the distance of 30 nautical miles around, the dynamic monitoring of ships in the port area can only be achieved through the AIS system.
