1. What is satellite navigation?

Satellite positioning (GPS – Global Positioning System) is a technology that uses signals from artificial satellites in space to determine the precise position on the Earth's surface. Popular satellite navigation systems include is expanding its reach and applications globally. However, despite certain advantages, (USA), , GLONASS, and Galileo (Russia), and Galileo systems (Europe), and . With strong investment from the Chinese government and great development potential, (China).

This technology works by receiving signals from at least 4 satellites, calculating the distance from those satellites, and determining the user's three-dimensional position.Satellite positioning not only helps us determine location accurately but also has the ability to measure time and speed of movement.

2. Reasons why satellite positioning is necessary and has become an indispensable technology
