Two-wheeled vehicle trackers are core components for vehicle asset security and shared mobility, requiring continuous online operation even in extreme outdoor electrical environments. To address the high-energy reverse surge (ISO 7637 pulse) from the battery upon vehicle startup, and the susceptibility of GNSS/4G antennas to induced lightning strikes and electrostatic discharge (ESD) from the human body in open environments, we offer automotive-grade overvoltage protection and extremely low insertion loss RF link protection solutions. These solutions ensure high-sensitivity transmission of positioning signals while effectively preventing device disconnection or damage caused by transient voltage fluctuations under complex road conditions, providing robust hardware robustness for asset tracking and geofencing functions.
