Introduction
With the continuous development of Global Navigation Satellite System (GNSS) technology, the four major satellite navigation systems - China's BeiDou (BDS), the United States' Global Positioning System (GPS), Russia's GLONASS, and Europe's Galileo - are being more and more widely used globally. The compatibility and interoperability of these systems are crucial for achieving high - precision and high - reliability positioning and navigation. This article will conduct an in - depth analysis of the antenna compatibility of these systems and recommend several excellent antenna products on the market, especially the antennas from EBYTE.
Data Analysis from Authoritative Institutions
According to the latest data released by the International GNSS Monitoring and Assessment System (iGMAS), the global coverage and positioning accuracy of the four major satellite navigation systems have been significantly improved. The specific data are as follows:
BeiDou (BDS): The global coverage reaches 95%, and the positioning accuracy reaches centimeter - level in the Asia - Pacific region. GPS: The global coverage is close to 100%, and the positioning accuracy reaches meter - level in open areas. GLONASS: The global coverage reaches 99%, and the positioning accuracy reaches meter - level in Russia and its surrounding areas. Galileo: The global coverage reaches 98%, and the positioning accuracy reaches centimeter - level in the EU region.
These data indicate that the four major satellite navigation systems have achieved a relatively high level of global coverage and positioning accuracy, with good compatibility and interoperability.
Analysis of Antenna Compatibility
To achieve the compatibility of the four major satellite navigation systems, antennas need to have the following characteristics:
Multi - frequency band support: Be able to receive and process signals in multiple frequency bands, such as B1I/B1C of BDS, L1 C/A of GPS, L1 of GLONASS, and E1B/C of Galileo. High gain and high sensitivity: Ensure that weak satellite signals can still be received in complex environments. Wide beam angle: Improve the signal reception range and coverage area. Strong anti - interference ability: Be able to work stably in complex electromagnetic environments.
