“ ISRO tech to curb accidents at open
Railway Crossings “
Indian Space Research Organisation (Isro) is helping the Indian Railways use its
satellite-based system to check accidents at unmanned railway crossings and
track train movements on a real-time basis.
Working on a pilot project with Isro, the railways has installed space agency-developed integrated circuit (IC) chips on some train engines. The Indian Regional Navigation Satellite System (or NaVIC) will be used to warn road users of approaching trains through hooters installed at unmanned road crossings.
Tapan Misra, director of Ahmedabad-based Space Applications Centre (SAC), confirmed that "Isro and the Indian Railways have been working together on this pilot project since June".
Explaining the functioning of the satellite-based system, Misra said,
"A hooter will be activated as soon as it gets signal from the IC chip
installed on a train when its engine is at a distance of 500 metres to 4 km
from the crossing. The hooter, linked to the navigation system, will thus warn
road users about the approaching train. It will become louder as the train
comes near the crossing and will fall silent after the train has passed."
Misra said, "The satellite-based system will also be used for tracking trains for disseminating information about their movement on a real-time basis." He said, "The system will also help the railways map the area covered by trains. The technology will come in handy at the time of a railway accident when it can be used to ascertain the exact location of a train."
ISRO and Shri
Tapan Misra deserve congratulations – and a BIG THANKS – for this initiative to
save lives , using NaVIC
I urge Shri Misra to extend the application of
NaVIC , to the problems outlined by me in my following E Mail to him :

Dear Shri Misraji :
Even as I hope that you
find a few minutes to consider the feasibility of my following suggestion , I
request you to take a look at my today’s blog , below
Warm Regards,
Hemen Parekh
================================================
Who says IMPOSSIBLE ?
Yesterday , in my blog , I had suggested
a solution for collecting “ Parking
Charges “ from 20 lakh vehicles that get parked on Mumbai streets at night
And collect fees from 30 lakh ( or whatever
number ) vehicles that ply on these streets , during the day time
Then extend this E-Governance to 200 MILLION vehicle
population in the entire country
A suggestion that could earn , City
Municipalities / State Governments and the Central Government , ( may be ) , Rs 100 crores per day !
You can find the detailed proposal at :

It is quite possible that some of the
readers may entertain doubts as to the feasibility of my suggestion
For them , I reproduce below , a news
report from Economic Times ( 31 May 2017 ) :
SOON, SATELLITE NETWORK TO
TAKE HD VIDEOS OF EARTH FROM SPACE
A British company is
planning to launch a network of satellites that can take high resolution
coloured images and videos of the Earth, which could be used to track individual vehicles from space.
A prototype spacecraft is set to be launched later this year for testing. Five more such platforms will follow in 2019.
The train of satellites will deliver rapid, high- resolution imagery of the planet in still and video formats. At best resolution, the images will capture features just
The images would enable
3D models of the ground to be constructed, and videos could be used to track moving objects such
as cars and other vehicles,
according to UK-based company Earth-i.
UK-based manufacturer Surrey Satellite Technology Limited (SSTL) has developed a new class of Earth observation spacecraft codenamed Carbonite.
The first in this series
was built in just six
months and was launched in 2015. The lessons learned from that
experience were then applied to the new satellite of the Earth-i constellation.
"We worked on Carbonite-1 with SSTL and
studied the performance to help develop the technology for Carbonite-2 which we will
be calling EiX2," said Richard
Blain, CEO of Earth-i.
"As for the constellation, we will launch that in batches of five," Blain told 'BBC News'.
"Our baseline plan
is for the first batch to go into one orbital plane, and then for the following
batches to go into different planes, so that not only do we get a
high-frequency revisit to places on Earth but we also get to see places at different times of the
day," he said.
Earth-i's constellation would be the first European system to provide HD video of activity on the ground.

Dear Shri Gadkariji ,
Here is your opportunity to change the face of TRANSPORTATION in
India !
Please ,
grab it !
