NavIC is, India’s very own desi Global Positioning System (GPS) is operational and is set to hit the market for public use early next year.
“The Indian Regional Navigation Satellite System (IRNSS) with an operational name of NavIC is currently being tested for its accuracy and is most likely to be available in the market for public use early next year,” said Tapan Misra, the director of Ahmedabad-based Space Application Centre (SAC).
India needed a constellation of seven satellites in space to complete its Indian Regional Navigation Satellite System (IRNSS), IRNSS was feat the country was able to achieve on April 28, 2016, when Indian Space Research Organisation (Isro) successfully launched IRNSS-1G, the seventh satellite in the series, and guided it to its orbit.
NavIC (‘Navigation with Indian Constellation’ whose Hindi meaning is ‘sailor’ or ‘navigator’), the name given by PM Narendra Modi after the launch of IRNSS-1G, is designed to provide accurate position information to users within the country. “Though American GPS with 24 satellites in a constellation has wider reach and covers the entire world, NavIC with seven satellites covers only India and its surroundings but is more accurate than the American system as it has more satelites per area. NavIC will provide standard positioning service to all users with a position accuracy of 5 metre radius. The GPS, on the other hand, has a position accuracy of 20-30 metre,” the SAC director said. The less the distance more is the accuracy of the navigation device in finding the real location.
India Own GPS
For many years now, India had been dependent on GPS, a project that the United States began in 1973. However, when the US denied GPS information during the Kargil war in 1999, the nation felt an urgent need for an indigenous navigation system.
NavIC has helped India enter the club of countries, which have their own positioning systems.
Besides America’s GPS, Russia has its GLONASS and European Union, its Galileo.
China is also in the process of building Beidou Navigation Satellite System.
Misra said, “Academic institutions have been roped in to do ground verification and calibrate data of NavIC to find its accuracy. We have developed digital chips to miniaturise technology (for use in mobiles and handsets) and experiments are on them. The system is being tested all across the country.” He said, “After the desi navigation system comes to market, big thing will be to popularise it (as American GPS dominates the navigation system market across the world).”
India Own GPS Explaining the scientific reasons for NavIC’s superiority over GPS,
Misra said, “Our system has a dual frequency (S and L bands). GPS is dependent only on L band. When low-frequency signal travels through the atmosphere, its velocity changes due to atmospheric disturbances. US banks on the atmospheric model to assess frequency error and it has to update this model from time to time to assess the exact error. In India’s case, we measure the difference in delay of dual frequency (S and L bands) and can assess the actual delay. Therefore NavIC is not dependent on any model to find the frequency error and is more accurate than GPS.”

MTN APN Configuration That Works – Mobile and Modem
MTN APN is what is required to enable internet connection on your phone. APN is an acronym for Access Point Name. Access Point Name is typically the name of the gateway connecting your internet enabled device to the web through an internet service provider, such as MTN.
Most often we run into the problem of missing APN configuration and can’t surf the web with our phone or modem. If you have your APN configured before now and you still cannot browse, make the listed below are in order.
- Data subscription balance
- Data monitor app threshold
- Other phones of same network can browse. Your inability to browse could be a general problem from the service provider at the moment.
- Network signal reception
In Nigeria you can fall into the hands of the wrong people, who will charge you high amount of money in the name of configuring your phone for browsing.
To get the configuration pushed automatically to your phone by MTN.
Send as a text message “Settings” to 3888. Without quotes.
If the above method fails to get you APN configuration, you can fall back to configuring it yourself which always works.
For Mobile phones, navigate to “mobile network” in settings through more connections option, and you should see APN configuration option there.
Note: If your device works just fine, you are advised not to go further. But if for a reason you deleted the pre-installed APN configuration and you want to get it back. You’re welcome. The configurations work for 2G, 3G and 4G network type.
MTN APN settings for smartphones (iOS and Android)
Note: For MTN 4G MiFi modems, the above configuration works for such devices.
MTN APN settings for modems (U.S.B stick modems)
Access Point Name is unique to every service provider and can come pre-configured in SIM cards. When you slot in a new SIM card into a phone, it goes through it’s initiation to the service provider’s system. The service provider can then push necessary configurations to the device. Devices with MTN SIM card making an internet connection must be configured with an APN to present to MTN.
MTN will then examine this APN to determine what type of connection should be created, for example: which IP addresses should be assigned to the wireless device, which security methods should be used, etc. All of which is done in a second by a programmed system.
