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.

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.
