Indian regional navigation satellite system or IRNSS is an autonomous regional satellite navigation system developed by the Indian Space Research Organisation its purpose is to provide services like GPS and once it starts working it will match standards of America's global positioning system and Russia's GLONASS.
The Indian regional navigation satellite system with its operational name NAVIC is an autonomous regional satellite navigation system. It provides accurate to real-time positioning and timing services of India and neighboring regions. It covers not only India but many other neighboring countries it covers regions extending 1500 kilometers or 930 miles around India.
The system not present consists of a constellation of seven satellites with two additional satellites on crowned as standby. Three of the seven satellites are located in geostationary orbit remaining four satellites are in inclined geosynchronous orbit. NAVIC provides two levels of service the standard positioning service for civilian and a restricted service for authorized users. Each satellite of this system costs 150 crore rupees and the PSLV XL version rocket costs 130 crore rupees. If we have our own network then tomorrow if Google decides to take a decision that no the service will be provided to India, what happens to the country. The entire country all kinds of activities will be suddenly crippled.

If we have our own system then nobody can threaten us by saying that we will stop this navigation. Satellite lies between latitude 30 degrees south to 50 degrees north longitude 30 degrees east to 130 degrees east. The responsibility for maintenance of this navigational satellite is on the crown segment which includes IRNSS spacecraft control facility is through navigation center IRNSS range and integrity monitoring stations, IRNSS network timing center, IRNSS CDMA ranging stations, laser ranging stations, IRNSS data communication network. So the satellite would know exactly where that object is and as the object moves. The satellite would track the whole thing so in this way we are doing the navigation but to have more precise navigation then you need to have more than three satellites to have a very accurate position of the object on the ground so for that we have seven satellites which give us very accurate positioning. The work of navigational satellite is standard positioning service and a precision service both will be carried on L5 and S band. The satellites weigh approximately one thousand three hundred and thirty kilograms and their solar panels generate 1400 watts. A messaging interface is embedded in it this feature allows the command center to send warnings to a specific geographic area. Fisherman using the system can be warned about a cyclone unlike GPS.

NAVIC has dual frequency S and L5 bands and if there is any obstruction in the atmosphere then also we can get accurate positioning and navigation signals and by analyzing that we will be able to know the accurate position. NAVIC or navigation with Indian constellation is our old indigenous global navigation satellite system it is designed to provide accurate positioning information service to Indian users and users in the region extending up to 1500 kilometers from its boundary. It will give in there it's very own navigation system which will provide information on location and time in all weather conditions back in the old days when we planned for a trip we bought printouts of maps and traveler guides nowadays people don't have to venture out they can plan their trips on laptops or mobile phones. Unquestionably GPS navigation and Google Maps have revolutionized the ease with which we can travel whether it be by car, boat, plane, train or foot.
