ISRO likely to launch NVS-01 navigation satellite

In News
  • The Indian Space Research Organisation (ISRO) is likely to launch NVS-01, a navigation satellite on-board the Geosynchronous Launch Vehicle or GSLV Mk-II.
NVS-01
  • Navigation Satellite-01, or NVS-01, is an advanced satellite that is scheduled for launch on May 29.
  • It is designed to replace the IRNSS-1G satellite that was launched in 2016.
  • With a mission life of 12 years, the NVS-01 satellite aims to enhance the existing navigation infrastructure by incorporating advanced technologies and capabilities.
  • This satellite will replace the IRNSS-1G satellite launched in 2016.
IRNSS-1G
  • IRNSS-1G was the seventh navigation satellite of the seven satellites constituting the IRNSS space segment.
  • Its predecessors—IRNSS-1A, 1B, 1C, 1D, 1E and 1F—were launched by PSLV-C22, PSLV-C24, PSLV-C26, PSLV-C27, PSLV-C31 and PSLV-C32 in July 2013, April 2014, October 2014, March 2015, January 2016 and March 2016, respectively.
  • To meet the positioning, navigation and timing requirements of the nation, ISRO has established a regional navigation satellite system called Navigation with Indian Constellation (NavIC).
  • NavIC was erstwhile known as Indian Regional Navigation Satellite System (IRNSS).
About NavIC
  • NavIC is designed with a constellation of seven satellites and a network of ground stations operating 24x7.
  • Three satellites of the constellation are placed in geostationary orbit and four satellites are placed in inclined geosynchronous orbit.
  • The ground network consists of a control centre, precise timing facility, range and integrity monitoring stations, two-way ranging stations, etc.
  • NavIC offers two services--standard position service (SPS) for civilian users and Restricted Service (RS) for strategic users.
  • These two services are provided in both L5 (1176.45 MHz) and S band (2498.028 MHz).
  • NavIC coverage area includes India and a region up to 1,500km beyond Indian boundary.
  • NavIC signals are designed to provide user position accuracy better than 20m and timing accuracy better than 50ns.
