Research on electromagnetic interference of vehicle GPS navigation equipment

In recent years, with the rapid development of the automotive industry, a large amount of electronic equipment was installed into the car. Due to the space constraints, lots of complex electromagnetic compatibility problems occur caused by the electromagnetic interference between different instruments. Therefore, for GPS navigation equipment installed inside the vehicle, a good electromagnetic compatibility and anti-jamming performance is significant. This paper describes the electromagnetic interference sources that affects the vehicle GPS navigation equipment, analysis the main interference propagation path, as well as this paper provides some of the optimization method to reduce the electromagnetic compatibility problems that may be encountered in the real work, which is critical for the safety and reliable operation of the GPS navigation equipment.
