Abstract

In one embodiment, a system receives, at a sensor unit, a global positioning system (GPS) pulse signal from a GPS sensor of the autonomous driving vehicle (ADV), where the GPS pulse signal is a RF signal transmitted by a satellite to the GPS sensor, where the sensor unit is coupled to a number of sensors mounted on the ADV to perceive a driving environment surrounding the ADV and to plan a path to autonomously drive the ADV. The system receives a first local oscillator signal from a local oscillator. The system synchronizes the first local oscillator signal to the GPS pulse signal in real-time, including modifying the first local oscillator signal based on the GPS pulse signal. The system generates a second oscillator signal based on the synchronized first local oscillator signal, where the second oscillator signal is used to provide a time to at least one of the sensors.
