What Is an Artificial Satellite?

Have you ever wondered what those glinting dots that cross the night sky are? Chances are,
you’re looking at artificial satellites.
These human-made marvels orbit the Earth, enhancing our capabilities in countless ways.
From enabling global telecommunications to facilitating advanced scientific research, the
impact of artificial satellites is profound and far-reaching.
Key Takeaways
● Global Communication: Artificial satellites provide the pathways for
telecommunication across the globe, making international broadcasts and global
internet access possible.
● Weather Monitoring: These satellites are pivotal in predicting weather, monitoring
climate changes, and supporting disaster management efforts.
● Navigation and GPS: Dependence on satellites for precise navigation systems is
universal—from aviation to everyday use in smartphones.
How Do Artificial Satellites Serve Us?
Imagine a world without live international broadcasts, without real-time weather apps, or
without GPS navigation. Hard to picture, right? That's the world without artificial satellites.
These devices are stationed in space to perform specific functions that support various
aspects of our modern lifestyle, from watching live events across the globe to tracking
hurricanes or navigating unfamiliar cities.
How Do Artificial Satellites Work?
To understand how these satellites stay in space, consider the delicate balance of gravity
and velocity. Satellites are launched with enough speed to propel them into orbit, which is a
careful balance that prevents them from veering off into space or falling back to Earth.
This precise orbit allows satellites to continuously perform their functions, be it capturing
images of the Earth's surface, conducting scientific experiments, or transmitting television
signals.
What Are the Different Types of Artificial Satellites?
Artificial satellites come in various forms, each designed for specific tasks:
● Geostationary Satellites remain in a fixed position relative to a point on Earth,
perfectly suited for weather monitoring and telecommunications.
● Polar Satellites travel north-south over the poles, allowing full Earth coverage as the
planet rotates, ideal for environmental monitoring.

● Navigational Satellites create networks like the GPS, which require highly precise
timing and positioning capabilities to function.
What Role Do Artificial Satellites Play in Technology?
Beyond their known applications, artificial satellites are fundamental to advancing
technology.
They test the limits of human ingenuity and spark innovations that trickle down to other tech
sectors. For instance, satellite technology has spurred advancements in materials science,
robotics, and even power systems that now benefit more terrestrial technologies.
What Goes Into an Artificial Satellite?
Breaking down a satellite into its core components:
● Power Source: Typically solar panels supplemented by batteries for the dark
phases.
● Transponders: These handle the communication back and forth between Earth and
the satellite.
● Antennae: Crucial for transmitting and receiving signals that aid in everything from
broadcasting to data collection.
Launching Artificial Satellites: A Monumental Task
Launching a satellite is a complex and costly endeavor that requires meticulous planning
and precision. It begins with a rocket launch, which propels the satellite into the desired orbit.
This process involves a team of engineers, scientists, and technologists coordinating to
ensure every factor, from the launch window to the satellite’s placement, is perfect.
