Key Features

  • The main task of QUESS satellite is to send secured massage between Beijing and Uenmqi.
  • It is named as Micius in the respect of 5th century BC Chinese philosopher.
  • It will be placed in sun-synchronous orbit at an altitude of 500 km.
  • It will complete one circle of earth in 90 minutes.
  • This satellite helps China to create hack-proof communications system by transmitting uncrack able keys from space to the ground.
  • It will be mainly applicable in ranges from highly secured military and government communications to online shopping.

Importance of QUESS Satellite:

  • Previously researchers were got success in sending quantum messages on land but this will be the first satellite-based quantum network which sends encrypted (hack proof) messages around the world very fast.
  • This launch will be beneficial for other possible uses of the technology.
  • China has created history in field of quantum technology by launching this satellite.

Quantum communication

  • Quantum communication increase ultra-high security in communication by using subatomic particles between two points.
  • It works as if any hacker tries to crack the message in Quantum communication it will alert the sender by changing its forms as a message to be changed or removed.
