Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the ionospheric scintillation monitoring system based on Beidou navigation is mainly composed of antenna, receiver and computer. The antenna receives the Beidou satellite signal and transmits the Beidou satellite signal to the receiver for processing. The receiver transmits the signal strength SI and carrier phase φ information of the satellite signal to the computer through the serial port line. The computer includes a data collection and analysis module and a system display module. The data analysis module processes the satellite signal strength SI and carrier phase φ information output by the hardware, and displays the data through the system display module.

[0028] In this embodiment, the antenna is a GNSS antenna, and the feeder is communicatively connected to the receiver. The receiver commu...

Abstract

The invention discloses an ionospheric scintillation monitoring system based on Beidou navigation, comprising: an antenna for receiving Beidou satellite signals, and transmitting the Beidou satellite signals to the receiver for processing; and carrier phase φ information are transmitted to the computer; the computer includes a data acquisition and analysis module and a system display module, and the data analysis module processes the satellite signal strength SI and carrier phase φ information output by the hardware, and performs data display through the system display module. Beneficial effects: this embodiment adopts an internal crystal oscillator source, which has stable frequency and low phase noise, and has strong anti-interference ability. The computer directly outputs the signal strength SI and carrier phase φ information of the satellite signal, which can be used to calculate the scintillation of the ionosphere, which is more convenient, simple, stable and reliable than the original equipment.

Description

technical field [0001] The invention belongs to the technical field of Beidou satellite monitoring and ionospheric monitoring, and in particular relates to an ionospheric scintillation monitoring system based on Beidou navigation. Background technique [0002] When radio signals transmitted by satellites pass through the ionosphere, the irregular structure of the ionosphere will cause rapid and random fluctuations in signal strength and phase. This phenomenon is called ionospheric scintillation. Ionospheric scintillation often causes bit errors and signal distortions in signals received by ground receivers, thus affecting the reliability and accuracy of navigation and communication systems. Therefore, the observation and study of ionospheric scintillation is not only an important means to study the irregular structure and changing characteristics of the global ionosphere, but also becomes a problem that people pay attention to as the global navigation and communication syste...
