Modernized GNSS acquisition and playback equipment to help develop the "Beidou dual-mode new signal system"
With the expansion of Beidou from the regional system to the global system, the Beidou satellite equipped with the new signal system has been launched. Various research institutions in China have gradually begun research on a new generation of Beidou signal system. The above picture shows the spectrum distribution of modern GNSS systems in various countries. It can be seen that modern GNSS signals, especially the new signal system of Beidou, have extremely wide bandwidth, and the general signal acquisition and playback equipment is difficult to meet the test requirements.

[Products] Focus on testing the full-frequency point recording and playback source of high-precision RTK receiver BY520
Because the competitiveness of high-precision RTK receivers lies in the complex environment adaptability, complex scenes such as ionospheric scintillation, urban canyon, electromagnetic interference, multipath interference, and constellation distribution weight of major navigation systems are difficult to reproduce accurately in real-world environments. Multi-system multi-frequency receivers such as RTK are often faced with the following problems...
