The traditional way to launch a satellite is to launch a satellite with a rocket. The use of a rocket to launch multiple satellites into orbit at the same time is an advanced space launch technology. Because it is necessary to spend tens of millions of dollars and a few years to prepare for a rocket launch, the workload is quite large and the scope is very wide, and it is inevitable that each launch will bear certain risks. One arrow and more stars can achieve more benefits at a lower cost, so it represents a new level of national space technology from one aspect. Below, the cold knowledge network shows you how the next arrow is implemented.

How a rocket launches multiple satellites

One arrow multi-star technology generally adopts two kinds of launching methods. One is to put multiple satellites at a time and enter an approximately the same running orbit. The satellites are separated by a certain distance. The second is to use the last stage of the launch vehicle. The engine is used to deliver satellites in batches, so that each satellite enters a different orbit. Obviously, the latter’s technology is more advanced.

In order to achieve more than one arrow, many technical key points need to be solved. The first is to improve the carrying capacity of the rocket in order to put a few satellites of higher quality into the orbit. Secondly, it is necessary to master the stable and reliable “star and arrow separation” technology, so as to be foolproof. The launch vehicle is in the final flight path and determines the best separation moment, so that multiple satellites are “on the spot” in their respective orbits. In addition, it must be considered that it is difficult to stabilize the loading of multiple rockets into the launch vehicle. Many satellites and rockets are in flight, and the electronic equipment contained therein may have special problems such as radio interference.

The first to achieve a multi-star technology is the United States. In 1960, the United States took the lead in launching two rockets using a rocket. In 1961, another arrow Samsung was realized. Russia has also used multiple rockets to launch multiple satellites. On September 20, 1981, China launched three scientific experimental satellites with the “Storm 1” rocket, becoming the fourth country in the world to master the technology of one arrow and many stars.

India completed a shot of ten stars and one arrow and seven stars in 2011, becoming the fifth country in the world to master more than one arrow, but India’s third brother did not stop there, although it started late, but it’s big. Ah, on February 15, 2017, India completed a 104-star launch with 104 satellites, setting a new world record.
