India's desi GPS 'NavIC' all set to navigate youQuote
Soon, your smartphones and car navigation systems may take directions from NavIC, the government's desi global positioning system (GPS) that has been developed to challenge the current GPS system of the West.
NavIC, an ambitious project pursued by the Modi government, is in the final stages of launch, and could soon be offered as an Indian counter to foreign systems currently being used by companies and other users.QuoteSawhney said that the smartphones that are currently being sold in the country depend on foreign GPS systems. "Once we are officially there, the NavIC can be embedded on chips and other devices as well as on vehicle navigation systems."
With seven satellites, the NavIC covers only India and its surroundings and is considered to be more accurate than the American system. NavIC will provide standard positioning service to all users with a position accuracy of 5 metre. The GPS, on the other hand, has a position accuracy of 20-30 metre.
Even more remarkable for Indian scientists is that NavIC is technically superior to the American GPS. "Our system has dual frequency (S and L bands). GPS is dependent only on L band.

Incorrect or misleading statements here. Single-frequency, pseudorange-based GPS positioning can achieve better than 5-metre accuracy under good conditions. Also, civil GPS is triple frequency! There are civil signal at L1, L2, and L5.

India launches UTRAQ, first 'desi' version of GPS module based on ISRO's IRNSSQuote
India has launched its very own GPS module. Known as 'UTRAQ', the module was introduced at an event in New Delhi, MobileTek and Rama Krishna Electro Pvt Ltd UTRAQ is a VTS module based on IRNSS to track locations. India, so far, had the GPS based applications in devices that were based on the feed given by US satellites.
L110 GNSS and L100 GNSS are the two modules launched. The L110 GNSS module is a compact NavIC module, while the L100 GNSS module is a smaller-sized POT (Patch on Top) IRNSS module. These modules can be used for different tasks other than tracking. These include ranging, command, control, timing and more.QuoteThe 'desi' VTS module's concept was first initiated for services and devices soon after tge Kargil War in 1999. The VTS module which is a part of IRNSS was pushed for when Pakistan troops took positions in Kargil. India, then asked for the GPS location data that was being handled by the US satellites. US refused to help India during the war situation. The GPS-based data by the US would’ve given some vital information, helping India manage the situation and control the damage.
UTRAQ's launch will help ISRO systems to provide accurate data without any dependency on foreign satellites. IRNSS is also said to provide the positioning for the Indian region 1500km around the Indian mainland as the primary service area. The UTRAQ modules support L1 and L5 bands, EPOTM orbit prediction, EASYTM self-generated orbit prediction and measures 18x16x2.3mm. -

Bengaluru to host ground station for Russian GPSQuote
Even as the work on having India's own navigation system using the Indian Regional Navigation Satellite System (IRNSS) or NavIC satellites is going on in full swing, the Indian Space Research Organisation (Isro) is gearing up to host a ground station for the Russian version of global positioning system - Global Navigation Satellite System (Glonass).
Officials said Bengaluru was selected largely because the city has the Isro telemetry, tracking and command network (Istrac). Istrac will host the Russian station too, said an official, adding that the "ground- measurement gathering station" will extend the existing partnership between Isro and Roscosmos, the Russian space agency. "The station will help get accurate locations and refine the satellite information," said Isro chairman Sivan K.Quote"The NavIC station in Russia will help enhance the baseline for orbit determination and of Ionosphere delays to improve the accuracy of the navigation solution," said a source. While Isro has put the satellites in space, the lack of indigenously developed systems to tap data from this constellation and take it to lakhs of Indians are not ready yet.
Bengaluru firm, Accord Software and Systems Private Ltd, along with Isro, has developed technology that can receive signals from the IRNSS satellites, compute locations and also decode its broadcast message as early as 2016. Also, Isro has designed a miniaturised version of the micro chipset to be used in navigation devices. However, the industry is yet to mass produce these receivers and chipsets, given that there is no apparent demand as most users prefer GPS. -

Soon, NaVIC handsets to bring fishermen under safety netQuote
In an effort to improve the safety of fishermen and strengthen the capacity to reach out to them quickly in case of unexpected calamities, the Fisheries Department is planning to distribute around 500 NaVIC handsets, the regional satellite navigation system developed by the Indian Space Research Organisation (ISRO), among them. Though the equipment actually costs about 8,000, the fisherman will have to spend only 1,500 to get it.
QuoteOfficials said the NaVIC handsets would help fishers get updates on extreme weather events with the support of regional control rooms and help rescue operators trace their location in case of rescue needs. It would also be helpful for fishers to get update on shoals, they added. The new device with bigger coverage area will help fishers overcome poor signal threat while using mobile phones. On such occasions, the mobile phones could be connected to the device using the bluetooth function. The device was developed following a request from the State government after studying the impact of Ockhi-related calamities.

What is there to be work in progress? NAVIC is already a success. It is used in Indian army as well as Indian shipping and boating vessels. It is limited to regions of about 5000km radius from India due to it not having global constellation.
Making chips of 180nm is already available in India. This is 2002 technology and hence is still usable. As a result, all Indian boats will get this system so as to maintain their route and prevent entering enemy waters -

Now that India has signed the BECA agreement with the United States, then what impact will that have on IRNSS/NAVIC?
Because America's GPS system provides more accurate and more extensive spatial navigation data, then is IRNSS then merely relegated to a marginal backup role?
