Pakistan also owns Satellites!

If you're thinking that Pakistan is behind in the space race so it doesn't own any satellite then you are wrong I will tell you the whole story. I admit that Pakistan is very behind in the space race but Pakistan owns not only one satellite but three satellites. Today we will discuss these satellites and I will share the information about these satellites which will surely increase your knowledge.

What do you think what does satellite means?

Is Satellite any engine or some robot? Don't worry. I will tell you. 

Satellites are celestial bodies that revolve around planets without any heat and light of their own.

They revolve around the earth and other planets. You almost heard the news that Elon Musk launched a new Satellite so these are machines that are used for communication, navigation, and some other purposes. Satellites are used in many fields.

Satellite definition Acc. to NASA

A satellite is a moon, planet, or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word "satellite" refers to a machine that is launched into space and moves around Earth or another body in space.

Why do we need a Satellite?

Satellites can view enormous portions of Earth at once due to their eagle's eye perspective. As a result, satellites can gather data more quickly and efficiently than devices on the ground.

Before satellites, TV broadcasts weren't extremely mobile. Only straight lines may carry television signals. As a result, they would not follow the Earth's curve but would abruptly fade off into space. Sometimes they would be blocked by mountains or large buildings. Another issue was making international calls on the phone. Long-distance or underwater telephone cable installation is challenging and expensive.

TV and phone calls are transmitted upward to a satellite using satellites. The satellite may then send them back down to various areas on Earth very immediately.

World First Satellite

The Sputnik 1 spacecraft was the first artificial satellite successfully placed in orbit around the Earth and was launched from Baikonur Cosmodrome at Tyuratam (370 km southwest of the small town of Baikonur) in Kazakhstan, then part of the former Soviet Union.

How does Satellite Work?

When the pull of Earth's gravity and the satellite's speed are equal, the satellite circled the planet. Without this equilibrium, the satellite would either fall back to Earth or shoot off into space in a straight path. At varied altitudes, velocities, and routes, satellites orbit the Earth. This is also the answer to the question that why satellites don't crash into Earth?

Paksat-1

Paksat-1, also known as Palapa-C1, HGS-3, and Anatolia-1, was a geosynchronous and communications satellite made and owned by the Boeing Company. It was leased to SUPARCO and changed its name to Paksat-1. On February 1st, 1996, it was successfully launched into orbit as Palapa-C1 with Indonesia serving as its initial customer. However, following the technical issues, the satellite was leased to SUPARCO in December 2002 and placed in an orbit with a 38° East longitude. Over 75 nations in Europe, Africa, the Middle East, South Asia, and Central Asia are covered by Paksat-1's C-band and Ku-band services. Government agencies, television networks, telecommunications firms, and data and broadband internet service providers were among its clients.

Pakistan Technology Evaluation Satellite (PakTES-1A)

PakTES-1A is a satellite that SUPARCO scientists, engineers, and technicians created on their own. PakTES-1A's main goal is to make the next significant advancement in establishing the domestic capability for the design and development of various kinds of satellites.

PakTES-1A is a 300 kg class small remote sensing satellite with a design life of 3 years placed in a sun-synchronous orbit at an altitude of around 600 km carrying an EO payload. PakTES-1A has been launched in a dual launch configuration along with Pakistan’s Remote Sensing Satellite (PRSS-1) using China’s LM-2C/SMA Launch Vehicle on 09-Jul-2018 from Jiuquan Satellite Launch Center (JSLC), China.

PAKISTAN REMOTE SENSING SATELLITE (PRSC-EOS)

To build and launch three additional optical remote sensing satellites by the year 2023, SUPARCO has launched the PRSC-EOS optical remote sensing application satellites initiative.
The satellites will join Pakistan's fleet of PRSS-1 and PakTES-1A remote sensing satellites that are currently in space. The domains of land mapping, agriculture categorization and assessment, urban and rural planning, environmental monitoring, natural disaster monitoring and management, surveying, protection of natural resources, and others will all make use of the remote sensing data.
