COUNTRY’S FIRST BALLOON-MOUNTED INTERNET NETWORK
Uttarakhand Chief minister Trivendra Singh
Rawat unveiled the country’s first balloon-
mounted internet network in a bid to bring
reliable internet access to the Himalayan state’s
most remote areas

•The aerostat balloon which is propelled
by helium gas can go up to 150-500 metre
height
•It has a light 25 km payload which is
equipped with a router, a weather station
and sensitive night vision cameras

Aerostat can float in the air for 14 days
Each aerostat is worth Rs 50 lakh to set-up and can
provide internet up to 7.5 km with the download
speed of 5 Mbps

UTTRAKHAND
Currently, 680 of 16,870 villages in the state lack
mobile connectivity or internet.
This technology will be used in remote areas that
are not connected to the internet, said the minister
at the launch.

NOTES
The balloon can be installed in the appropriate vehicle and taken from one place to another, as required, can be
activated in less time.
Besides, according to experts, the aerostat balloon can help measure some 18 weather and environment related
parametres. “Some of the few parametres are humidity, temperature, wind velocity and high altitude conditions,”

MAIN TYPES OF BALLOONGas balloon - Contrary to the hot-air balloon, the
envelope of which is inflated by hot air, the gas balloon
contains a gas less dense than the air with identical
temperature, generally hydrogen, or helium. The gas
balloon is thus closed hermetic not to let escape the gas
finding it inside.

HOT AIR BALLOON•The hot-air balloon is an aerostat where the lift is
assured by the warmed air contained in the envelope.
The difference of density with the colder, surrounding
air, creates a push assuring the lift (pushed by
Archimède). The preservation in air temperature of the
envelope requires the emport of a fuel and a burner.

AIRSHIP•An airship is an aircraft lighter than air, also called
aerostat, containing devices intended to insure the lift as
well as propulsion systems conferring him a total
steerability. Dirigibles distinguish themselves from other
types of balloons, by their vertical and horizontal
movements.
