In response to natural disasters, the functional value of Beidou satellite news is highlighted.

　　Recently, heavy rainfall has swept through many areas, causing serious harm to some areas. For example, Zhuozhou City, Hebei Province, suffered a rare flood disaster due to large-scale precipitation, which caused great losses to people's lives and property.

　　According to statistics, as of 10: 00 on August 1st, there were 133,913 people affected by the disaster in Zhuozhou, and there were 146 villages affected by the disaster, covering an area of 225.38 square kilometers. According to official data, Zhuozhou has a permanent population of more than 650,000. The number of people affected by the disaster has accounted for 1/5 of the total population. Some researchers said that the flood in Zhuozhou was mainly caused by the excessive flow of Beijuma River and Dashi River.

　　At present, many rescue teams have arrived in Zhuozhou, and the rescue process is arduous. It is understood that some trapped people are still in a state of power failure and disconnection. It is difficult for the rescue team to determine the specific location of the trapped people and the number of trapped people. Only people who are familiar with the local situation can be used as guides to guide the search and rescue work. Moreover, due to the turbid water, rescuers did not understand the underwater situation, and some of the rescued kayaks were cut by sharp objects at the scene, which made the rescue more difficult.

　　In this rainstorm, in the face of power failure, many affected people have no way to ask for help. So, what should we do in such a situation? In fact, there have been cases of being rescued by Beidou satellite signals, and a distress signal can be sent out through a mobile phone equipped with Beidou satellite function. For example, some mobile phones such as Huawei Mate 50 series, Mate X3 series and P60 series all support two-way sending and receiving Beidou satellite messages. This function may not be used at ordinary times, but it is used once in a lifetime. Some people say that if Huawei Beidou is used, it can really prepare for emergencies, and many tragedies may not happen.

　　It is understood that the Beidou satellite technology carried by Huawei is a high-orbit satellite with a distance of up to 36,000 kilometers, and its communication capability has been further improved through high-gain algorithms and new communication protocols. Specifically, Huawei's Beidou satellite message function, even in the mountains where the signal can't be covered, or in the desert no man's land, or in the case of distress at sea, earthquake rescue, etc., can also send messages and fix the trajectory through Changlian APP, so that it can be connected at any time. This function can be said to be of great value, so it is called the technology of "piercing the sky upwards".

　　Under the background of global climate change, extreme weather and climate events occur frequently, frequently and repeatedly, with a wide impact, and the risks brought by meteorological disasters are gradually increasing. When the disaster comes, facing the complicated situation, the first thing we should do is to make a good defense guide and make full use of scientific and technological means to reduce the disaster risk. Obviously, the communication function of Beidou satellite is necessary. In the rescue process of the rescue team, if the trapped people carry Beidou satellite mobile phones, it will undoubtedly greatly speed up the rescue time.
