 How will earth life be changed by Beidou when Tianwen goes to Mars?


In the field of agriculture, Beidou not only provides simple positioning information, but also combines with sensor technology and hydraulic control to realize the whole process automation of agricultural machinery.

In terms of transportation, Beidou system has the positioning ability of centimeter level, which can track the travel path and time of public transport, automobile and other vehicles in real time, and alleviate various practical problems such as traffic congestion and parking difficulty. In the future, bus, train, plane, etc. will only be more and more accurate, and we can grasp the travel time more reasonably.

Beidou also plays an important role in the financial system. We all know that finance is a race against the clock field. Beidou can provide high-precision timing for the financial system. More importantly, it can improve the feasibility and traceability of transactions and promote the healthy development of the industry.

No matter when, where and what kind of industry, Beidou is quietly changing our life. What are the skills behind this powerful skill point?

Lets take positioning and navigation as an example to understand the positioning principle of Beidou satellites three ball rendezvous, that is, only three satellites are needed to realize the positioning of any point on the earth.

Now lets look at the Beidou system. First of all, we can search for at least three Beidou navigation satellites anywhere on the earth, which we call a, B and C. At any given moment, the coordinates of the three satellites are definite values, which are assumed to be (XA, ya, ZA), (XB, Yb, ZB), (XC, YC, ZC).

Given the location of the three satellites and the distance between the user and the three satellites, we have to solve the users positioning. We assume that it is (Xu, Yu, Zu). Are you familiar with it? Yes, its a system of quadratic equations with three variables.

Although we look very complicated, in front of the powerful computing power equipped by Beidou, we are all a piece of cake every minute. Of course, dont be confused by this simplicity. After all, only ensuring the stable transmission of signals depends on the accumulation of countless technicians and time.

Commercial players in space

Space shows the possibility of the future. Every tiny achievement may change the development process of human society. Therefore, in addition to the national heavyweight such as Beidou, countless commercial aerospace enterprises have embarked on this road of exploration. They have contributed to social progress in a lower cost and more convenient way, such as Tianyi Research Institute.

As one of the first batch of commercial aerospace companies in China, Tianyi Research Institute focuses on the development of aerospace systems and loads for commercial markets. Through microsatellites, it provides short-term, low-cost, one-stop space science experiments and technology verification services for scientists, scientific research institutes, enterprises and individuals at home and abroad, so as to make space within reach.

As a leading commercial aerospace institution in the industry, Tianyi Research Institute has also won the favor of many investment institutions, including Junlian capital and Lenovo star, two financial investment institutions of Lenovo holdings. In 2015, Lenovo star invested in angel financing of Tianyi Research Institute, and in 2018, Junlian capital led the investment in round B financing of Tianyi Research Institute.

From Beidou to tianwen-1, they are unique marks in Chinas space history. Since 1956, China has initiated the space industry from scratch, built space launch sites, developed and launched satellites and missiles. Every step is arduous and full of glory. In 1970, Chinas first man-made earth satellite dongfanghong-1 was successfully launched at Jiuquan satellite launch site, and China became the fifth country in the world to launch a satellite; in 2003, Chinas first astronaut Yang Liwei successfully flew around the earth in the Shenzhou-5 spacecraft, and now Chinas manned space program has entered the third step; in 2013, change-3 In 2020, the three steps of the Beidou system, which has experienced 26 years of growth, has been successfully completed, while Chinas Mars exploration mission has just started. These successive explorations, let the shining Chinese name, repose the vast dream of human star sea. Source: editor in charge of mass news: Chen Tiqiang_ NB6485
