Quasi-Zenith Satellite System (QZSS)

  • It is Japanese version of GPS.
  • It is also called Michibiki system. Michibiki means guidance in Japanese.
  • It is intended for civilian use, with a claimed positioning accuracy down to mere centimetres.
  • The QZSS constellation of 8 satellites will trace out a figure-8 pattern over Japan, the Western Pacific, and Australia.
  • The Michibiki system can cover the Asia-Oceania region and works with the US-operated GPS to provide higher level of precision than previously possible with fewer satellites in visible range.
  • It will become operation in 2018 with four satellites focusing on country and wider region.
  • It will provide global positioning and timing services across frequencies ranging from 1575.42 MHz to 2 GHz.
