Two Indian Scientists are Helping ISRO to Protect Satellites

          As more and more objects are launched into space, it is becoming cluttered with satellites, both functional and non-functional. Two Indian scientists Arun Balaji and Sanat K. Biswas at Delhi Indraprastha Institute of Information Technology have started working on an algorithm that will be able to predict the chances of collision of the satellite with any object in one month's advance. 

Sanat K. Biswas is working with his colleague Arun Balaji Buduru to develop the algorithm.The duo has been receiving research funding from the National Supercomputing Mission (NSM) for two years.



 

Agencies like the Indian Space Research Organisation (ISRO) or the Defence Research and Development Organisation (DRDO) use algorithms to monitor the safety of the vital Indian satellites and take preventive measures, if needed in case the satellites are at risk of being hit by a stray piece of space debris.


Sanat K. Biswas who developed the algorithm informed in an interview that at least 20,000 pieces of space debris is present in the low Earth orbit at a speed of 7 km/second. If they collide with any active satellite, the damage will be similar to a bullet shot. 


 



 


 


Currently the US Department of Defense maintains a satellite catalogue on objects in Earth’s orbit. It has a Space Surveillance Network that can track discrete objects as small as 2 inches in diameter in low Earth orbit and about 1 metre in geosynchronous orbit. It has officially catalogued about 15,000 objects in orbit. The total number of tracked objects now exceeds 21,000.


However, if an Indian satellite were at threat of collision, the country would have to depend on the US for information. Additionally, the accuracy of the data is also not ensured. The two scientists are thus working to ensure safety for the nation’s satellites.

Although there are rumours surrounding the software hacking into smartphones and tapping call records, phishing data and much more, the Information Technology Minitre Ashwini Vaishnaw stated in the Lok Sabha that hacking is not possible with the robust technology India has Further, he blamed the press media for spreading the rumours. He said in a statement, “A highly sensational story was published by a web portal last night. Many over the top allegations were made around this story. The press reports appeared a day before the monsoon session of Parliament. This can’t be a coincidence."   He further said that there have been various claims earlier as well but even then all the ministers and party members have claimed the rumours to be fake
