Abstract

The invention discloses an anti-electromagnetic interference method and device of Beidou positioning module. The device is equipped with Beidou positioning receiver with anti-electromagnetic interference that comprises a narrow-band receiving antenna, a first-level BPF band-pass filter,a LNA(low noise amplifier), a second-level BPF band-pass filter, a EMI filter and a signal processor. The narrow-band receiving antenna, the first-level BPF band-pass filter the LNA(low noise amplifier), the second-level BPF band-pass filter and the signal processor are connected in turns. One end of the EMI filter is connected to power source , and the other end is connected to the LNA(low noise amplifier)and the signal processor respectively. The anti-electromagnetic interference method and device of Beidou positioning module has the advantages of small volume, convenient installation, low power consumption and strong anti-jamming capability. After extensive testing, the Beidou positioning module can be properly positioned in the case of the normal work of communication station.

Description

technical field [0001] The invention relates to the technical field of satellite navigation and positioning, in particular to a Beidou positioning module anti-electromagnetic interference method and device. Background technique [0002] The positioning information of buoys at sea and various sensor information need to be sent to remote control stations through communication stations. Due to the influence of buoy size and installation size, the transmitting antenna of the communication station is very close to the satellite positioning device, and the higher harmonics of the signal transmitted by the communication station will fall in the frequency band of Beidou / GPS. Different sea buoys are set to different frequency points, and the number of buoys is large. Therefore, the frequencies of higher harmonics of communication stations installed on different buoys are also different. In this way, satellite positioning devices need to interfere with communication stations in differ...
