Abstract

The invention relates to the technical field of lightning protection, in particular to a GNSS (Global Navigation Satellite System) positioning receiver lightning and surge protection device and a GNSS positioning receiver. The device comprises an interface protection module which is arranged at the front end of an interface of target equipment and is used for carrying out lightning protection and surge protection on a power supply input line of the target equipment; the power supply protection module is arranged in a built-in power supply circuit of the target equipment and is used for carrying out lightning protection processing on the built-in power supply circuit so as to suppress an induced current introduced from a power supply interface of the built-in power supply circuit; and the communication protection module is arranged in a communication line of the target equipment and is used for carrying out lightning protection processing on the communication line so as to suppress induced current introduced from a communication interface of the target equipment. The device can improve the anti-thunder and anti-surge effects of the positioning receiver and improve the signal quality of the positioning receiver, thereby effectively eliminating or reducing the negative effects caused by thunder and lightning and reducing the possibility of damage to the receiver.
