Satellite navigation technology has drastically improved over the years. Learn how everything works by checking out this guide.

What Should You Know About Satellite Navigation?

Satellite navigation, also known as the global navigation satellite system (GNSS), has revolutionized how we navigate and locate objects on the planet. This is evident from the fact that the global satellite navigation market size was valued at $160.69 billion in 2020 and is projected to reach $320.73 billion by 2028, growing at a CAGR of 9.02% from 2021 to 2028.

As technology continues to evolve, satellite navigation systems are expected to become even more accurate and reliable, with new applications emerging. By addressing the challenges and harnessing the potential of this technology, we can ensure that it continues to benefit society while minimizing any negative impacts

This technology uses a network of space satellites to provide precise location and timing information to GPS devices on the ground. Keep reading to gain a greater understanding of what satellite navigation is.

How Does Satellite Navigation Work?

Satellite navigation works by using a network of satellites in space that orbit the Earth at a specific altitude and speed. These satellites emit signals that are picked up by GPS devices on the ground. The GPS devices then use these satellite signals to determine their precise location, as well as the time and velocity.

The accuracy of satellite navigation depends on the number of satellites the device can “see” and the quality of the signals received from these satellites.

Different Satellite Navigation Systems

There are different satellite navigation systems in operation around the world. Let’s take a look at some of the most popular ones.

GPS

The most widely used system is the Global Positioning System (GPS). The United States government operates it. The GPS comprises a network of 24 satellites in orbit and provides location and timing information to GPS devices worldwide.

GLONASS

The Russian government operates the GLONASS. It consists of a network of 24 satellites in orbit.

Galileo

The European Union operates the Galileo. It consists of a network of 24 satellites in orbit.

BeiDou

The Chinese government operates the BeiDou. It comprises a network of 35 satellites in orbit and provides location and timing information to GPS devices in Asia and the Pacific region.
