首先要知道这两个传感器发布的ROS消息格式：在开发之前，需要在ROS环境中安装这两个msg。sudo apt install ros-melodic-nmea-msgssudo apt install ros-melodic-nav-msgsGPS Device Sensor发布的格式是GPGGA格式，需要经纬度信息的可以直接从字符串中取。GPS Odometer Sensor这里的position指的是UTM坐标系下的xyz，orientation是在UTM坐标系下的四元数，也是.

环境：Xavier Ubuntu18.04ROS Melodic解决方法：修改系统时间为当前时间即可。（手动和联网自动效果一样，没网手动修改，有网选自动）

环境：Xavier Ubuntu18.04ROS Melodic报错内容：CMake Error at /opt/ros/melodic/share/cv_bridge/cmake/cv_bridgeConfig.cmake:113 (message):Project ‘cv_bridge’ specifies ‘/usr/include/opencv’ as an include dir,which is not found.解决办法：sudo gedit /opt/ros/melodi

1.添加源使用国内USTC源速度会快一点sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.ustc.edu.cn/ros/ubuntu/ $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'2.添加公钥sudo apt-key adv --keyserver hkp://pool.sks-keyservers.net --recv-

我使用的是系统是Ubuntu18.04，ROS版本Melodic。1.创建ROS包cd catkin_ws/srccatkin_create_pkg point_cloud_processing pcl_ros roscpp rospy sensor_msgs std_msgs cd ..catkin_make 2.添加.cpp文件#include <iostream>...
