Why is NAVIC better than GPS?
GPS also uses a single frequency band and this makes calculations a bit more complex. NavIC satellites use dual frequency bands (L5-band and S-band), which is why the system is relatively more accurate than GPS (that uses a single band and makes compensation for error due to signal deterioration by the atmosphere).
The IRNSS is an independent regional navigation satellite system developed by India. It is designed to provide accurate position information service to assist in the navigation of ships in the Indian Ocean waters.
Why is Indian Regional Navigational satellite system IRNSS needed How does it help in navigation answer in 150 words?
IRNSS will focus on only Indian periphery and will help in navigation of shipping as well as air traffic. The IRNSS will work like GPS by providing location to users based on their position. It will help in providing location, map navigation and other location based services.
India’s homegrown navigation system, NAVIC, is now in the same league as the US, Russia and China after being approved by the International Maritime Organisation (IMO). Powered by a constellation of seven satellites, NAVIC is capable of scanning areas up to 1,500 kilometres beyond India’s own borders.
It enables more accurate location performance, and faster time-to-first-fix (TTFF) position acquisition, and improved quality of location-based services. Some more applications of NavIC are: Aerial and marine navigation.
What is the difference between GPS and Irnss?
GPS has 31 satellites, while IRNSS has only 7 satellites. All these 7 satellites will be visible to the ground receiver all the time.” IRNSS. Though GPS has 24 satellites, the number of satellites visible to the ground receiver is limited.
Which is an autonomous regional satellite system developed by ISRO?
IRNSS
IRNSS (Indian Regional Navigational Satellite System) IRNSS is an autonomous regional satellite navigation system being developed by ISRO (Indian Space Research Organization).
Indian Regional Navigation Satellite System (IRNSS) : NavIC IRNSS is an independent regional navigation satellite system being developed by India.
Why is Indian Regional Navigational satellite System Needed How does it help in navigation Upsc?
The IRNSS System provides navigation solution all time with position accuracy better than 20m during all weather conditions, anywhere within India and a region extending about 1500 km around India.
IRNSS-1A
IRNSS-1A is the first navigational satellite in the Indian Regional Navigation Satellite System (IRNSS) series of satellites been placed in geosynchronous orbit.
Indian Regional Navigation Satellite System
The Indian Regional Navigation Satellite System (IRNSS) is officially called NAVIC which is an acronym for NAVigation with Indian Constellation. The regional geo-positioning system has been designed in India by ISRO to provide accurate positioning in India and around the Indian mainland.
What is ISRO Satellite navigation?
ISRO is committed to provide the satellite based Navigation services to meet the emerging demands of the Civil Aviation requirements and to meet the user requirements of the positioning, navigation and timing based on the independent satellite navigation system.
To meet the user requirements of the positioning, navigation and timing services based on the indigenous system, ISRO is establishing a regional satellite navigation system called Indian Regional Navigation Satellite System (IRNSS). This is a Satellite Based Augmentation System (SBAS) implemented jointly with Airport Authority of India (AAI).
Why did the Indian military develop the ISRO system?
The system was developed partly because access to foreign government-controlled global navigation satellite systems is not guaranteed in hostile situations, as happened to the Indian military in 1999 when it was dependent on the American Global Positioning System (GPS) during the Kargil War.
What is Indian Positioning System (ISP)?
This is an independent Indian Satellite based positioning system for critical National applications. The main objective is to provide Reliable Position, Navigation and Timing services over India and its neighbourhood, to provide fairly good accuracy to the user.
