Electromagnetic Compatibility Design for Mobile Target Positioning Terminals

Based on the identified deficiencies in the existing electromagnetic compatibility (EMC) design of mobile positioning terminals, a comprehensive EMC design solution is proposed from an engineering perspective. This solution effectively suppresses the impact of radiated interference, transient pulse interference, and ground loop interference on the operation of the positioning terminal. Considering the market deployment of tens of thousands of units, the adoption of this solution has reduced the return rate of terminals due to EMC issues from 20% to 0.1%.
