Indian Regional Navigation Satellite System: Scientists Discuss India's 7-Satellite Navigation System

The Indian Space Research Organization expects the system to be operational by July 2016, to send signals worldwide and to be accurate to nearly 20 meters. Four satellites are already in orbit.


Indian Space Research Organization (ISRO) has played a key role in the development of our nation over the years. With its impressive space missions, ISRO has clearly put India on the map when it comes to space exploration. It is really breathtaking what we have achieved in a short span of 46 years. (ISRO was officially established in 1969)

Beginning Thursday, Isro will hold a major meeting in Bangalore involving location and navigation device manufacturers, mobile phone manufacturers and global information system (GIS) technology developers presenting to them the advantages of using the IRNSS technology over the current GPS technology.
During the two-day meet, Isro will demonstrate how the seven IRNSS constellation satellites once operational by July next year, will be significantly more accurate than the American GPS system. The meeting will also be attended by senior scientists from Space Application Centre (SAC) Ahmedabad. 

GSAT-15 satellite with GAGAN payload is slated for launch by November 10

IRNSS is ISRO's initiative to build an independent satellite navigation system to provide precise position, velocity and time to the users of Indian region. The system is designed with a constellation of seven spacecraft and a vast network of ground systems. 
With the addition of fourth spacecraft IRNSS-1D in March 2015, the minimum satellite requirement is met and independent positioning is now possible for the first time using an Indian satellite-based navigation system. 
He said, "as we make it global, global users will be able to take advantage. Otherwise, now only regional users can take advantage of IRNSS."

Odd-Even Rule-- Delhi To Restrict cars from Jan 1st To cut off Pollution

  Arvind Kejriwal  is trying to save Delhi and its condemned citizens from a calamity. That Delhi's air will soon turn into poison and choke us is a fait-accompli. Somebody will have to clean it, if not us, then the generation that follows. Drastic measures can be deferred — at huge costs — but they are inevitable. The Delhi government announced on Friday each private car and two-wheeler will be allowed on the city’s roads only every other day from next year in a bid to even the odds stacked against authorities in their efforts to clean up the Capital’s toxic air. Private vehicles will be allowed to run on the streets on alternate days depending on whether their licence plates end in even or odd numbers, the government declared a day after it faced criticism from the Delhi high court over the city’s mounting pollution problem. The method, more commonly known as road space rationing, is followed in various forms across the world, though experts said implementation coul...

The less you know about 4G LTE ,VOLTE and JIO 4G

Many of Us think that 4G is same for every phone,So many of us see features in a phone if it supports 4G we will be in a mood that it is a good affordable mobile and lets buy a JIO sim.but there is difference in these 4G devices they are differentiated LTE and VOLTE. i.e,Long term Evolution and Voice over LTE What is 4G LTE There a thin difference between 4G and 4G LTE  Both 4G and 4G LTE refer to networking standards that are starting to replace the older 3G data networks used by wireless carriers, but they all use different technology. For those pondering the abbreviations, “3G” stands for Third Generation, “4G” stands for Fourth Generation and “4G LTE” stands for Fourth Generation, Long Term Evolution. Volte supported Devices Volte is Voice Over Long Term Evolution(LTE)  where voice calls are made with the help of data, where data is converted into voice signals and transmitted. as the same way you make whats app calls but in this case both should have...
