The marine surveying and mapping in the northern waters is accurate to centimeters, and Beidou can help. What can Beidou be used for?

For ships sailing at sea, water depth is an important condition for their navigation safety. In 20021year, the marine surveying and mapping work in the northern sea area was started, and the surveyors updated the maps in the ports and waterways of key water transport areas such as Bohai Bay and Liaodong Bay. ?

First, the sharp weapon of engineering construction?

Beidou? The system can provide high-precision positioning for many projects such as construction, excavation, subgrade, planning and design, geophysical exploration, oil drilling and crustal movement monitoring, so it can greatly improve the productivity of engineering construction and improve the accuracy and efficiency of related activities, which is more than three times higher than that of traditional surveying methods. For example, the application of this technology makes the construction accuracy of roads and bridges reach millimeter level, which greatly improves the measurement and construction accuracy of important transportation infrastructure such as tunnels and subways, and reduces the construction cost. ? Beidou? After this technology is applied to the deformation monitoring of highway slopes and bridges, it is not limited by visibility conditions, and the selection of points is flexible. According to the monitoring needs, the monitoring points can be arranged on the characteristic points sensitive to the deformation of deformed bodies.

Second, help precision agriculture increase production?

The precise positioning function of navigation satellite can be widely used in farm planning, field mapping, soil sampling, tractor navigation, crop field detection and sowing speed selection, fertilizer, pesticide and yield detection system. It can improve the accuracy of using pesticides, herbicides and fertilizers, and at the same time better control the diffusion of chemical substances, thereby reducing costs, expanding production, creating new environmentally-friendly farms, increasing crop yields in different regions and under different conditions by 3%-50%, and greatly reducing manpower, capital (machinery and equipment) and raw materials (seeds, fertilizers, pesticides, other chemicals, fuel, oil and electricity) for agricultural production. It is estimated that the average output increment driven by satellite navigation technology can reach 10%, and the average cost can be reduced by 15%. Based on what? Beidou? The agricultural machinery operation supervision platform has realized the remote management and precise operation of agricultural machinery, served more than 50,000 sets of agricultural machinery equipment, increased the output of precision agriculture by 5%, and saved the oil consumption of agricultural machinery by 10%.

Third, the helper of marine fishery?

What is fishing? Beidou? Satellite navigation system is one of the earliest and most widely used industries. Fake? Beidou? The user machine can not only navigate the ship, but also cross it? Beidou? Unique short message communication technology, reporting the position of ships and people on board. China has installed about 654.38 million fishing boats? Beidou? User machine. For fishermen, Beidou? The SMS function of has at least four advantages. First, contact with family members to meet emotional needs. The second is to contact the domestic market, and you can notify the pre-sale in advance to increase your income. The third is to contact the surrounding fishing boats in time to save themselves and help each other when in distress. Fourth, accurate positioning can avoid disputes over cross-border fishing. Our country has passed? Beidou? Early warning of dangerous meteorological information such as tens of thousands of tropical cyclones has been sent to fishermen, many fishing boats, fishermen and patients. Rescue has been implemented, and more than 654.38 million people have been rescued, effectively avoiding many foreign-related incidents and recovering economic losses of hundreds of millions of yuan.
