Abstract
In one embodiment, a sensor unit receives a first GPS message from a GPS sensor, where the sensor unit is coupled between sensors and a perception and planning system of an autonomous driving vehicle (ADV). The sensor unit determines a type of the first GPS message by matching a predetermined field of the first GPS message with a list of predetermined data patterns. Each of the predetermined data patterns corresponds to one of the predetermined types of GPS messages and decodes a payload of the first GPS message using a decoding algorithm associated with the type of the first GPS message.
