2. A satellite is an artificial object which has been
intentionally placed into orbit. Such objects are
sometimes called artificial satellites to
distinguish them from natural satellites such as
Earth's Moon.

3. Communication is the act of conveying
meanings from one entity or group to
another through the use of mutually
understood signs and semiotic rules. The
main steps inherent to all communication
are: The formation of communicative
motivation or reason.

4. A communications satellite is an artificial satellite that
relays and amplifies radio telecommunications signals
via a transponder; it creates a communication channel
between a source transmitter and a receiver at different
locations on Earth. Communications satellites are used
for television, telephone, radio, internet, and military
applications. There are over 2,000 communications
satellites in Earth’s orbit, used by both private and
government organizations.

5. The concept of the geostationary
communications satellite was first
proposed by Arthur C. Clarke,
along with Vahid K. Sanadi building
on work by Konstantin Tsiolkovsky.
In October 1945 Clarke published
an article titled "Extraterrestrial
Relays" in the British magazine
Wireless World.
The article described the fundamentals
behind the deployment of artificial
satellites in geostationary orbits for the
purpose of relaying radio signals. Thus,
Arthur C. Clarke is often quoted as
being the inventor of the
communications satellite and the term
'Clarke Belt' employed as a description
of the orbit

6. The first artificial Earth satellite was Sputnik
1. Put into orbit by the Soviet Union on
October 4, 1957, it was equipped with an
on-board radio-transmitter that worked on
two frequencies: 20.005 and 40.002 MHz.
Sputnik 1 was launched as a major step in
the exploration of space and rocket
development

9. The Bangabandhu Satellite-1 is the first Bangladeshi
geostationary communications and Broadcasting
Satellite. It was manufactured by Thales Alenia Space
and launched on 11 May 2018.[1] The project is being
implemented by Bangladesh Telecommunication
Regulatory Commission (BTRC) working hand-in-hand
with US based Space Partnership International, LLC.
and was the first payload launched by a Falcon 9 Block
5 rocket of SpaceX.
Bangladesh Government formed a Government owned
Bangladesh Communication Satellite Company
Limited, BCSCL with the aim to operate the
Bangabandhu Satellite-1.

10. The satellite is located at 119.1°E longitude
orbital position and provides
broadcasting and
telecommunication services to rural
areas in Bangladesh.
It also supports profitable services, including
direct-to-home (DTH) services.
It offers Ku-band and C-band services across
Bangladesh and its territorial waters of the Bay of Bengal,
India, Nepal, Bhutan, Sri Lanka, Philippines, and Indonesia.
The satellite enables the nation to
save approximately BDT1.08bn ($14m) currently
being spent on satellite rents each year.
BTRC also plans to launch follow-on
series of BD-2 and BD-3 satellites in phases.
