If your Android or IOS smartphone has the Google Maps app installed, then you are using the Global Positioning Service (GPS) satellite navigation system. Among smartphone users, where GPS is popular, very few people know that GPS is not the only satellite navigation system. Russia itself owns GLONASS, there are the same European Union and China Galileo and BeiDou Navigation Satellite System (BDS).
Like the US, Russia, China, and the European Union, Indians will soon be available to use indigenous GPS (Global Positioning System). The name of this indigenous GPS is ‘NavIC’ Navigation with Indian Constellation.
What is the NavIC system?
In India, the Indian Space Research Organization (ISRO) has developed the Indian version of GPS, which has been named Navigation with Indian Consensus (NavIC). If you have a question about why you need NavIC despite the GPS, then during the 1999 Kargil war, the US had refused to give the GPS data connected with the Pakistani army to India. For the first time, India felt the need for its satellite navigation system.
Indian Regional Navigation Satellite System (IRNSS) is a system of eight satellites known as Navic (Navigation with Indian Constellation). To function smoothly, eight satellites were to be set up in the Indian Space Sector. Its first satellite IRNSS-1A was launched from PSLV-C22 launch vehicle on July 1, 2013, and the last satellite of this system was installed in space on April 12, 2018
What is the service coverage?
These satellites can accurately tell the distance between two places with a purity of 20 meters. It is capable of not only informing India but also about 1500 km from the Indian border. In this sense, this navigation system covers entire South Asia.
With the launch of the Indian Regional Navigation Satellite System (IRNSS), PM Narendra Modi launched Navic Satellite Navigation System in 2016. ISRO is talking to Qualcomm and Broadcom for integrating it into smartphones.
For smartphones, a new chip will be required for Navic Sport and chipmakers can do this work. India is one of the largest smartphone markets, in such a way, Navic Sport can be a game-changer in Devices. Navic Navigation System focuses solely on India and ISRO says it will give more accurate information than GPS. With this help, position Accuracy of up to 5 meters will be available.
GPS where only works on the L band, Navic Dual Frequency is powered. This works for both S and L band with the help of the band and therefore can give more precise information. A total of 8 Indian Regional Navigation Satellites (IRNS) are working for Navic and are continuously gathering data related to the location.
What are the applications of IRNSS?
IRNSS:- Indian Regional Navigation Satellite System
This indigenous system is not only for ordinary citizens but also for the Indian Army. It mainly provides services in two types. First Standard Positioning Service (SPS) which will be available to all citizens.
The second Restructured Service (RS) will be available only to the army and to some special users. Since the army has an indigenous system, our military activities will not be known to the other or the enemy country. With this we will be able to maneuver several times in the monitored range.
On the other hand, our air force and the army will easily find the military bases of the enemy country. It would be easy to demolish guided missiles. It can help in terrestrial, air and marine navigation; disaster management; Vehicle tracking and fleet management; Integration with mobile phones; Exact time; Capture mapping and geodetic data; Terrestrial navigation assistance for travelers and passengers; Scene and voice navigation for drivers.
What are the details of the Indian satellite?
Seven satellite of Indian Regional Navigation Satellite System (IRNSS) Like its six predecessors, the weight of IRNSS-1G was 1,425 kilograms. All 7 satellites are traditionally configured. All IRNSS used the most powerful ‘XL’ version of the Polar Satellite Launch Vehicle, equipped with 6 strap-ons, each 12-ton propellant. Three of the 7 satellites are located in the appropriate orbital slot in the geostationary orbit. In the remaining four geosynchronous orbits, there are two different planes with necessary tilt and equatorial crossings.
