ISRO is doing to boost the use of NavIC, India’s version of GPS

Key Points

 

To promote the use of ‘NAVigation with the Indian Constellation’ (NavIC), the Indian version of GPS, the Indian Space Research Organisation (ISRO) will introduce the L1 frequency in all its future satellites.

The seven satellites in the NavIC constellation currently use two frequencies for providing positioning data — the L5 and S bands. However, most mobile System on Chips(SoCs) and wearable devices support the L1 band.

To overcome this drawback, ISRO announced that new satellites from NVS-01 onwards which are meant to replace these satellites will also have L1 frequency.
L1 frequency is one of the most commonly used frequencies in the Global Positioning System (GPS), which even the less sophisticated, civilian-use devices such as smartwatches are capable of receiving.  Thus, with this band, the use of the NavIC in wearable devices and personal trackers that use low-power, single-frequency chips can go up.

NavIC:

NavIC, or Navigation with Indian Constellation is an independent stand-alone navigation satellite system developed by the Indian Space Research Organization(ISRO). NavIC was originally approved in 2006. It was expected to be completed by late 2011 but only became operational in 2018. NavIC consists of eight satellites and covers the whole of India’s landmass and up to 1,500 km from its boundaries.

Currently, NavIC’s use is limited. It is being used in public vehicle tracking in India, for providing emergency warning alerts to fishermen venturing into the deep sea where there is no terrestrial network connectivity, and for tracking and providing information related to natural disasters.

The main difference is the serviceable area covered by these systems. GPS caters to users across the globe and its satellites circle the earth twice a day while NavIC is currently for use in India and adjacent areas.

Moreover, like GPS, there are three more navigation systems that have a global coverage — Galileo from the European Union, Russia-owned GLONASS and China’s Beidou.
QZSS operated by Japan is another regional navigation system covering the Asia-Oceania region with a focus on Japan.

Key Points

 

India plans to commission 20 nuclear power plants by 2031, adding nearly 15,000 MW in power generating capacity, the government told the Lok Sabha.

 

The first of these 20 nuclear power plants, a 700 MW unit, is expected to be commissioned in 2023 at Kakrapar in Gujarat, which already has three atomic power generating units operational.

According to a written reply by Minister of State in the PMO Jitendra Singh, the 500 MW Prototype Fast Breeder Reactor at Kalpakkam is likely to be operational in 2024, followed by two 1,000 MW units at Kudankulam in 2025.

 

Two 700 MW units at Rawatbhata in Rajasthan are likely to be completed by 2026, while another two 1,000 MW units are likely to be completed at Kudankulam by 2027, he said. Two 700 MW units are expected to be completed at Gorakhpur in Haryana by 2029, the minister said listing out details of projects under consideration.

In addition, government had accorded administrative approvals and financial sanctions for building 10 atomic power units of 700 MW each at Gorakhpur, Haryana (units 3&4), Kaiga, Karnataka (units 5&6), Chutka, Madhya Pradesh (units 1&2) and four units at Mahi Banswara in Rajasthan.

These 10 nuclear power units are likely to be completed progressively by 2031, Singh said. In a written reply to a separate question, Singh said the Kundankulam Nuclear Power Project (units 1&2) had contributed 48,382 Million Units of electricity to the national grid between 2017-18 and 2021-22.

Nuclear Power Plants in India:

There are 22 reactors in the nation running above 80% plant load factor as of 2021, with a combined installed capacity of 6780 MWe.

 

There are four light water reactors and eighteen pressurised heavy water reactors (PHWRs) in total (LWRs). Under Homi J. Bhabha’s direction, India’s nuclear energy programme was started around the time of independence.

The Mumbai-based Apsara Research Reactor is Asia’s first nuclear power plant. India has a little indigenous uranium deposit; hence the country must import uranium from other nations to fuel its nuclear power industry. Russia has been India’s main source of nuclear fuel since the 1990s.

Why In News

SpiceJet has been awarded the 'Safety Performer of the Year' award by GMR Delhi Airport Awards.

 

SpiceJet has been awarded the ‘Safety Performer of the Year’ award by GMR Delhi Airport Awards for being the top performer among the self-handling airlines and as it has been able to reduce ground safety violations significantly. SpiceJet ground handling team at Delhi Airport achieved this performance through constant focus on quality improvements, innovation and hard work. Moreover, their role in minimising incidences of ground safety violations ensured compliance with safety guidelines and regulatory requirements.

SpiceJet:

Recently, the airline was audited by the International Civil Aviation Organization (ICAO), and its operations, safety processes, and systems were found to be strong and at par with the global best practices and safety standards.

The airline was the only scheduled Indian airline part of the audit conducted by ICAO, the United Nations aviation arm. The audit of SpiceJet safety systems “helped India achieve” its highest-ever safety ranking in ICAO audit

Earlier this year, as many as 90 pilots of Spicejet were restrained from flying Boeing 737 Max aircraft after the DGCA found they were not properly trained. That was followed by multiple snags in its aircraft.
