Ros python node receives GPS RTK serial port messages and forwards ros topic messages

The code is a ROS (Robot Operating System) node for reading RTK (Real Time Dynamic) data from a GPS device and publishing it via the ROS topic.

C ++ version receive serial gps rtk data, and then publish it as a ros node topic, with code

The code implements a ROS node that receives serial data and forwards it into ROS messages. Here is a simple explanation of the code:

sensor_msgs in ros :: how to assign values to each field of NavSatFix

We first imported the ROS-related header file, and then created a sensor_msgs::NavSatFixtype message object navsat_fix_msg. Then, we assigned values to the various fields of the message object:

The code comes from livox_mapping, let me briefly say the conclusion:
