The Indian Regional Navigation Satellite System (IRNSS) recently become fully-operational and has been provided with the operational name of NavIC (Navigation with Indian Constellation). Developed by the Indian Space Research Organization (ISRO) with the objective of offering positioning, navigation and timing (PNT) to the users on a variety of platforms with a 24 hour x 7 day service availability under all weather conditions - in its service area with a position accuracy of < 20 m throughout India and within the region of coverage extending about 1500 km beyond. nih.gov

Having an autonomous regional satellite navigation system of one’s own offers strategic autonomy in military operations. The GPS that we have known and used all along is the satellite-based radio navigation system owned by the US government and operated by the American Air Force. During the Kargil War 20 years ago, the US refused to provide India critical information on the movement and precise location of Paki enemy troops. toi A need for an indigenous satellite navigation was felt earlier, but Kargil experience made the nation realize it's inevitability. Geopolitical needs teaches us that some countries can deny us the service in times of conflict, a way of arm twisting.

With an accuracy of <10 m on Restricted and Encrypted Service (RES) while an accuracy of <20 m on Standard Positioning Service (SPS), IRNSS will offer 2 level of services for very differing purposes. isro.gov.in \PDF]) Almost all Military and Reconnaissance applications will utilize RES while SPS will be available for civilian uses. unvienna \PDF])

The IRNSS space segment architecture consists of 3 satellites in GEO (Geostationary Orbit) at 32.5°, 83° and 131.5° East while 4 satellites in geosynchronous orbit placed at inclination of 29° with longitude crossing at 55° and 111.75° East forming an analemma. isac.gov.in Out of the 4 GSO satellites, the first sat IRNSS-1A failed in orbit due to atmoic clock malfunction. On August 31, 2017, sat IRNSS-1H was meant to replace defunct IRNSS-1A, failed to deploy due to malfunction in payload fairing mechanism. Though failures are not uncommon in space missions of even developed nations, India is not in a position where it can afford even relatively minor glitches neither financially nor in terms of reaching the higher goals it has set for itself. firstpost

IRNSS Analemma

Unlike GPS which is dependent only on L-band, NAVIC has dual frequency (S and L bands). When low frequency signal travels through atmosphere, its velocity changes due to atmospheric disturbances. US banks on 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, the actual delay is assessed by measuring the difference in delay of dual frequency (S and L bands). Therefore, NavIC is not dependent on any model to find the frequency error and is more accurate than GPS. toi

Studies have also shown marked improvement in GDoP (Geometric dilution of precision) values when IRNSS is used in conjunction with GPS constellation for position fix in primary coverage region of IRNSS. Hence IRNSS can be augmented with GPS to improve position accuracy in the given region. ias.ac.in

The IRNSS is being developed parallel to the GAGAN (GPS Aided GEO Augmented Satellite Navigation) program that in essence use GPS signals for navigation but after making them much more reliable for safety critical applications like in civil aviation., the ISRO SBAS (Satellite Based Augmentation System) version of an overlay system for GNSS signal corrections. earth.esa.int As of 2013, the statutory filing for frequency spectrum of Global Indian Navigational System (GINS) satellite orbits in international space, has been completed. hindubusinessline GINS is supposed to have a constellation of 24 satellites, positioned 24,000 km (14,913 mi) above Earth. wikipedia)

On Sep 24, 2019 Global mobile telephony standards body, 3GPP, gave its approval to NaVIC (Proposed jointly by Reliance Jio and ISRO). 3gpp.org \XLSX]) The approval has been given for the system’s use in Rel-16 LTE and Rel-17 5G NR specifications, paving the way for wider commercial adoption of NaVIC, allowing it to be integrated with 4G, 5G and internet of things (IoT). 3gpp.org \ZIP]) Thus, electronics companies can start designing and building integrated circuits and mass manufacture other products uniquely created to be compatible with NavIC. From what all scant information I was able to gather it seems Broadcom was first to introduce BCM47756 3gpp.org \ZIP]) chipset integrated with NavIC and Xiaomi Mi8 was the first phone to have the capabilities. insidegnss Will the introduction of indigenous satnav be another step closer towards being a global power? Comments open.

And in the last, here's 19th-Century Vision of the Year 2000 by Jean-Marc Côté and other artists issued in France in 1899, 1900, 1901 and 1910. Originally in the form of paper cards enclosed in cigarette/cigar boxes and, later, as postcards, the images depicted the world as it was imagined to be like in the then distant year of 2000.
