The Galileo navigation system stands out among numerous satellite navigation systems thanks to its advanced core technologies and unique design advantages. Firstly, Galileo employs a completely new signal structure, including multiple frequency bands such as E1, E5, and E6. This multi-band design enables Galileo to provide higher positioning accuracy and stronger anti-interference capabilities, maintaining stable and reliable service even in complex environments such as urban canyons or densely forested areas.

Secondly, the Galileo satellites were equipped with high-precision atomic clocks, a key component for achieving accurate time synchronization. Each Galileo satellite carried two passive hydrogen atomic clocks and two rubidium atomic clocks, which worked together to ensure that time errors were controlled within the nanosecond range. This extremely high time accuracy is invaluable for applications requiring precise time synchronization, such as financial transactions and power dispatching.

Furthermore, the Galileo system introduces three different service models: Open Service (OS), Commercial Service (CS), and Public Regulation Service (PRS). The Open Service provides basic positioning functionality free of charge to ordinary users; the Commercial Service offers higher-precision data support for specific industry needs; and the Public Regulation Service is primarily used in government and security-related fields to ensure the secure transmission of sensitive information. This multi-layered service architecture not only meets the needs of different user groups but also enhances the overall competitiveness of the system.

It is worth mentioning that the Galileo navigation system was designed with compatibility and interoperability with other global satellite navigation systems in mind. This means that users of Galileo devices can simultaneously receive signals from other systems, thereby further improving positioning accuracy and reliability. This open and collaborative approach has earned the Galileo system greater recognition and support in the global market.
