Different Types of Satellite Positioning Systems
In our previous article, we explored how to choose the right Time Server for enterprise use (click here to read) https://www.throughwave.co.th/2020/01/13/users-problem/. In this section, we will introduce satellite positioning systems that are commonly used with Time Servers today. The Global Positioning System (GPS) is used to determine location and time by calculating signals transmitted from satellites orbiting the Earth. These satellites send precise timing signals, allowing receivers to determine their position anywhere on the planet. However, did you know that GPS is not the only satellite system used for positioning and time synchronization?
GPS is the world’s first satellite navigation system, developed in 1957 by scientists in the United States. Initially designed for military use, it was later made available for public use. Today, GPS is widely adopted worldwide and remains the most commonly used system for positioning.
Currently, many countries have developed their own satellite positioning systems similar to GPS. Here are some notable examples:
1. GLONASS (Global Navigation Satellite System) Developed by Russia, GLONASS is one of the most widely used positioning systems after GPS. It has been enhanced to provide accurate positioning even in urban areas with tall buildings.
2. Galileo Developed by the European Union along with partner countries such as India, Israel, South Korea, and Saudi Arabia. While some devices and smartphones support Galileo, it is not yet as widely adopted as GPS or GLONASS.
3. BeiDou Developed by China, BeiDou initially provided services in limited regions. However, the Chinese government has announced that the system would achieve global coverage by 2020.
4. QZSS (Quasi-Zenith Satellite System) Developed by Japan, QZSS has a unique figure-eight orbit different from other satellite systems. It is designed to complement GPS and is positioned to enhance coverage over Japan and the Asia-Pacific (APAC) region.
Wavify TimeNX – Supporting Multiple Satellite Systems: The Wavify TimeNX Time Server supports both GPS and GLONASS, which are currently the most widely supported satellite systems across electronic devices. By operating both systems together, TimeNX improves signal reception, increases positioning accuracy, and reduces risk. If one system becomes unavailable, the server can continue operating using the other system—ensuring uninterrupted performance.
