NavIC - the Indian GPS Goes Limited, Needs New Satellites Soon

NavIC (Navigation with Indian Constellation) or IRNSS (Indian Regional Navigation Satellite System) has got a major setback, as it's services have became limited. In a written reply in the Lok Sabha, Union Minister of State for Space Dr Jitendra Singh said only three satellites in the NavIC constellation are presently capable of providing Positioning, Navigation and Timing (PNT) services. 

To provide basic positioning service, a minimum of 4 operational satellites are required in orbit. Hence, the NavIC constellation with 3 active satellites cannot provide standalone positioning service; however, timing service is functional. 

However Indian government said users are not facing operational vulnerabilities because NavIC is now used alongside other global satellite navigation systems in a multi-constellation Global Navigation Satellite System (GNSS) environment as receivers to combine signals from GPS, Galileo, GLONASS and NavIC for navigation.

Chandannagar Heritage Trails: Nritya Gopal Smiti Mandir & Chandannagar Library


On the G.T. Road, Bagbazar (
বাগবাজার)  of Chandannagar (yes like Kolkata, French colony Chandannagar also has a Bagbazar), just opposite to HP Petrol Pump there is a beautiful palace - now the once-white domes have became blackish with the time but you can't miss it. And if you observe it closely, you would find the name of the building - 'Nitya Gopal Smriti Mandir O Chandannagar Pustakagar' (নৃত্যগোপাল স্মৃতি মন্দির ও চন্দননগর পুস্তকাগার) is inscribed on the top of the building. Many locals call it as 'Old Library'.

Chandannagore Heritage Trails: Chandannagar Rani Ghat

Today if I shout about Chandannagore (চন্দননগর), everyone would talk about the Jagadhatri Puja (জগদ্ধাত্রী পুজো) and the light decoration, Surya Modak's Jolbhora (সূর্য মোদকের জলভরা) and the Strand. For anytime the city's Strand by the riverside is most loved location in Chandannagore or Chandannagar. 

Well that's not all of Chandannagar - during the British Raj, it was a French Colony till 1st October, 1950 and therefore became the natural sanctuary of many of the Indian revolutionists, most famous is definitely Rishi Aurobindo. Earlier locals call the town as Forashdanga (ফরাসডাঙ্গা) - the land of the French. That's similar to old Danish colony Serampore's old local name - Dinemardanga (দিনেমারডাঙ্গা) - 'দিনেমার' the word was originated from 'Danskere'.

The Strand, the main attraction of the city today, is basically almost 2 km long riverside road. It will remind Pondicherry's promenade for sure. And most prominent colonial buildings are here.

Hyderabad, the capital city of Telengana, a state in South India, is also a paradise for food lovers. It was the capital of Andra Pradesh since India's independence, and remains so till 2014 when the state of Andhra Pradesh was divided into Telengana and Andhra. Till 2024 Hyderabad remains the capital of both states, and later Andhra got its own capital - Amaravati. 

This story is all about the food of Hyderabad. At present Hyderabad has became of hub of IT indutries, but Hyderabadi cuisine is a major part of its culture. In fact Hyderabad was the first Indian city listed as a creative city of gastronomy by UNESCO in 2019. In 2025 Lucknow got the recognition as second Indian city.

Airtel Launched Priority Postpaid - India's First Network Slicing AI Network

Airtel Priority Postpaid

Globally it is believed that odds of 'G' are not successful commercially, as 1G, 3G and now 5G - as investment did not give much pleasure to the revenue book. However as 6G is not coming til 2028-2030, I guess operators are looking ways to make money out of 5G. 

Earlier I explained how Jio leveraging their deployment of 5G-Standalone (5G-SA) technology to launch its Air Fiber services and has become world's largest operator on Fixed Wireless Access (5G-FWA) in July last year. Jio expanded its FWA services with UBR (unlicensed band radio) over 5GHz band.
