What is NVS-01? Blog Image

Overview:

The Indian Space Research Organisation (ISRO) is all set to launch the navigation satellite 'NVS-01' onboard its Geosynchronous Satellite Launch Vehicle (GSLV) from Sriharikota in Andhra Pradesh.

Why in news?

  • The GSLV-F12/NVS-01 mission is designed to deploy the NVS-01 navigation satellite into a geosynchronous transfer orbit (GTO).

About NVS-01:

  • It is the first in the series of second-generation navigation satellites built by ISRO's UR Rao Satellite Centre in Bengaluru.
  • At present, India uses its Navigation with Indian Constellation (NavIC) series of satellites for civilian and defence navigation in the Indian mainland and even 1500 kms beyond India's borders. 
  • NVS series of satellites will sustain and augment the NavIC with enhanced features.
  • This series incorporates L1 band signals additionally to widen the services.
  • For the first time, an indigenous atomic clock will be flown in NVS-01.

What is Navigation with Indian Constellation (NavIC):

  • It is a regional navigation satellite system  established by the ISRO to meet the positioning, navigation and timing requirements of the nation.
  • NavIC was erstwhile known as Indian Regional Navigation Satellite System (IRNSS).
  • It is a constellation of seven satellites that work with a 24X7 network of ground stations while orbiting above Earth.
  • Three satellites are placed in geostationary orbit and four in inclined geosynchronous orbit. 
  • Coverage: The NavIC coverage area includes India and a region up to 1,500km beyond the nation’s boundary.
  • Services offered:
    • It offers two services -- Standard Position Service for civilian users and Restricted Service for strategic users.
    • The system is used in terrestrial, aerial, marine transportation, location-based services, personal mobility, resource monitoring, surveying and geodesy, scientific research etc.

What is Geosynchronous Transfer Orbit (GTO)?

  • To attain geosynchronous (and also geostationary) Earth orbits, a spacecraft is first launched into an elliptical GTO.
  • There on, the satellite will independently use its onboard propulsion systems to perform orbit-raising manoeuvres and reach its intended orbit.

 


Q1) What is Geosynchronous Transfer Orbit (GTO)?

To attain geosynchronous (and also geostationary) Earth orbits, a spacecraft is first launched into an elliptical GTO. There on, the satellite will independently use its onboard propulsion systems to perform orbit-raising manoeuvres and reach its intended orbit.
