Experimental Research on the Effect of ESD on Beidou Navigation Receiver

With the gradual improvement of the Beidou system, the Beidou navigation receiver begins to be widely used, but due to the low power of navigation signal, the navigation receiver is easily disturbed and cannot work normally. This paper take Beidou navigation receiver as experiment object, and study the sensitive voltage and effect under the condition of ESD, The experiment shows that the positioning function of the receiver is not affected by ESD, but the data output serial port is susceptible to interference, so that the upper computer cannot obtain the effective information of navigation and positioning in time. The conclusion provides a basis for the electromagnetic protection of the navigation receiver.
