Chongqing's transportation system introduces China's Beidou satellite positioning system. In the future, Chongqing's vehicle ships will encounter unexpected situations, and even if communication is interrupted, they can get in touch with the outside world in time, and travel will become more secure. Yesterday, the Chongqing Municipal Transportation Commission organized experts to pass the acceptance and acceptance of the Beidou system in the city's public transportation and the Three Gorges ship shipping application research project. The system will be gradually promoted in the city's vehicle ships.
The Beidou satellite navigation system is a satellite positioning and communication system developed by China itself. Zhang Taixiong, chief engineer of the Municipal Traffic Commission, said that Chongqing is located in the mountains, and there are more blind spots in the conventional communication network. In addition, there are various terrains and natural disasters, and ground communication is often interrupted. Currently, the US GPS positioning system is commonly used. Without the communication function, it is difficult for the trapped person to inform the outside world of the situation. The Beidou system is capable of transmitting information via satellite and has an obvious role in dealing with emergencies.
