Re: [time-nuts] new longwave time service planned in India

India has IRNSS, their own GNSS augmentation system.
FWIW, S Korea is about to start testing its own radio time signal but the
range is only 500 km or so as I remember.

Cheers

Hi

It’s also *way* cheaper than putting up your own satellite based timing and 
navigation 
gear. I suspect that the whole “what if this or that set of  sat’s have 
issues?” thing is 
beginning to sink in ….

That is quite a surprise that a country is setting up a long wave system
these days. They still have to raise the money but it seems like a
semi-private arrangement. Even more interesting is they suggest 3
locations. Something to try to find in the VLF bands some day in the future.

[time-nuts] new longwave time service planned in India

[Pieter-Tjerk de Boer]

Hi,

Apparently India plans to build two longwave transmitters for a national
time signal service:
http://www.thehindu.com/todays-paper/tp-national/coming-huge-towers-to-publicise-right-time/article23377284.ece

No technical details such as frequency and modulation are given, nor whether
the carrier will also serve as a reference frequency.

They do mention involvement of the German EFR company, who operate three
transmitters between 129 and 139 kHz for remotely controlling equipment
and broadcasting time, using 200 baud FSK. One might speculate similar
signals will be used for the new India service.
