Navic vs GPS which is better

today we will learn how NavIC has an edge over GPS NavIC stands for Navigation in Indian Constellation Prime Minister Narendra Modi named it NavIC in honor of our Fishermen /boatmen
Navic had total 9 launches Starting from IRNSS 1A to IRNSS IRNSS 1A had a Atomic clock failure ISRO launched IRNSS 1h for replacement ,but launch failed
Know the reason of the failure with animation by clicking the 'i' button Lets do a specification wise comparison of the two systems we will compare the Syetms on 3 major criterias The signal is on purpose scrambled
to prevent the potential use of NavIC by our enemies NavIC has a special restricted mode ~1 m accuracy for the armed forces is incredible GPS also has a similar accuracy Both GPS and NavIC can increase their accuracy by using local networks upto ~ 10 m. Google uses a similar technique to improve the accuracy of GPS in their maps app. GPS i.e. Global positioning system can provide positioning across the globe US had invented GPS so it could provide its armed forces and missiles with global navigation IRNSS stands for Indian Regional navigation Satellite System IRNSS primarily serves mostly for india and its neighbours ISRO has designed the system to give more accuracy in the neighbouring countries for obvious reasons. GPS seems to be better when it comes to coverage But i'll discuss later on why its not the best IRNSs 1A now functions as a Data communication satellite since its clocks failed although GPS has more satellites Satellites in the NavIC constellation alwys face INDIA since they are in a Geostationary orbit In a geostaionary orbit the orbital period is 24 hrs , which means the satellite will be always facing india. This means the satellite will always be in the line of sight with India When you point you Dish Tv towards space You actually point it towards a geostationary satellite in space. NavIC currently has 3 geostationary and 4 geosynchronous satellites . Geosynchronous satellites also have a 24 hr orbital period , but are slightly inclined. hence it appears to move in a 8 shape over time So in total we have 3 Geostationary and 4 geosynchronous .Total of 7 so far GPS satellites are in a medium earth kindoff orbit hence they are relatively faster If you take specifications into consideration looks like the GPS is better , but.... NavIC's 7 satellites are designed by and for India . They are always in line of sight GPS satellites are relatively moving fast Since NavIC's satllites are so high they can work even in canyons or steep valleys . GPS satellites may have issues in canyons and valleys India will have full control over NavIC we can extract any kind of data and use it at our will without notifying anyone. US denied GPS service to India during Kargil war leading to many lives being lost , although India did win the battle. It is speculated that GPS signal was scrambled during Brahmos missile test in 2012. There are several advantages to having our own Navigation system. ISRO can even improve the system further and is flexible ISRO is planning to add more satellites in the future with its own Atomic Clocks NavIC will improive in the future and we will have total control over it Hope you liked this.
