From UPSC perspective, the following things are important :
Prelims level : IRNSS, IMO, NaVIC
Mains level : IRNSS
The Indian Regional Navigation Satellite System (IRNSS) has been accepted as a component of the World Wide Radio Navigation System (WWRNS) for operation in the Indian Ocean Region by the International Maritime Organization (IMO).
Try this PYQ:
With reference to the Indian Regional Navigation Satellite System (IRNSS), consider the following statements:
- IRNSS has three Satellites in geostationary and four satellites the geosynchronous orbits.
- IRNSS covers entire India and about 5500 sq. km beyond its borders.
- India will have its own satellite navigation system with full global coverage by the middle of 2019.
Which of the statements given above is/are correct?
(a) 1 only
(b) 1 and 2 only
(c) 2 and 3 only
What is IRNSS?
- The IRNSS, with an operational name of NavIC (acronym for Navigation with Indian Constellation) is an Indian regional satellite navigation system that provides accurate real-time positioning and timing services.
- It covers India and a region extending 1,500 km around it, with plans for further extension.
- The system currently consists of a constellation of seven satellites, with two additional satellites on ground as stand-by.
- The constellation is in orbit as of 2018, and the system was expected to be operational from early 2018 after a system check.
- It will provide two levels of service, the “standard positioning service”, which will be open for civilian use, and a “restricted service” (an encrypted one) for authorised users (including the military).
Benefits of the move
- This move will enable merchant vessels to use IRNSS for obtaining position information similar to GPS and GLONASS.
- This will assist in the navigation of ships in Indian ocean waters within the area covered by 50°N latitude, 55°E longitude, 5°S latitude and 110°E longitude (approximately up to 1500 km from Indian boundary).
Back2Basics: International Maritime Organisation (IMO)
- IMO is the UN specialized agency with responsibility for the safety and security of shipping and the prevention of marine pollution by ships.
- Its primary purpose is to develop and maintain a comprehensive regulatory framework for shipping and its remit today includes safety, environmental concerns, legal matters, technical co-operation, maritime security and the efficiency of shipping.
- IMO is governed by an assembly of members and is financially administered by a council of members elected from the assembly.
