New laser system to accurately detect space junk, Chinese researchers developed an algorithm

Beijing. Scientists in China have improved the accuracy of the technology to detect junk spread in the Earth’s orbit in space. Scientists say that the new method will easily find a safe passage for the spacecraft.

The junk or debris spread in space includes old satellites that are no longer in use, rocket remains and similar devices that collide and break apart. Although scientists have developed a system for identifying junk that is orbiting the Earth in space, it was impossible to identify a small and fast-moving piece of debris.

Scientists develop an algorithm

According to the study published in the journal ‘Laser Applications’, scientists have developed an algorithm for accurate identification of such debris. Through this, the success rate of accurate detection of space debris from laser ranging telescope has been greatly improved.

The fragment can be traced up to 1500 kilometers away

Tianming Ma of the Chinese Academy of Surveying and Mapping reported that fragments up to one square meter up to a distance of 1500 kilometers can be detected since the new technology. In laser ranging technology the distance of any object is measured by laser reflection from that object.

A new algorithm improves the accuracy of laser ranging telescope

Scientists said that the laser reflected from the surface of space debris is very weak. This weakens the calculation of space debris. Scientists have made some improvements in the last few experiments, but with the previous technology, only one kilometer level of debris was able to get accurate information. For the first time in the new study, it was found that the accuracy of laser ranging telescope has improved significantly through the new algorithm. Scientists also demonstrated the accuracy of this new technology at Beijing’s Fangshen Laser Range Telescope Station.
