sudo chmod a+x ./install_geographiclib_datasets.sh

# 为避免下载速度慢，直接复制（假设文件在 ~/GeographicLib/）
sudo cp -r ~/GeographicLib/ /usr/share/

依赖不能装在base环境下，详见：

PX4 运行 make px4_sitl_default gazebo 报错-CSDN博客

git clone https://github.com/PX4/PX4-Autopilot.git PX4_Firmware

cd PX4_Firmware

git checkout -b xtdrone/dev v1.13.2

git submodule update --init --recursive

make px4_sitl_default gazebo

可成功打开gazebo

gedit ~/.bashrc
######添加######
source ~/catkin_ws/devel/setup.bash
 source ~/PX4_Firmware/Tools/setup_gazebo.bash ~/PX4_Firmware/ ~/PX4_Firmware/build/px4_sitl_default
 export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/PX4_Firmware
 export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:~/PX4_Firmware/Tools/sitl_gazebo
######添加######
source ~/.bashrc

在文档末尾添加

####用于测试是否安装成功#####
roslaunch px4 mavros_posix_sitl.launch
######Tips######

从百度网盘里下载并解压！！！！！

cp -r ~/models/ ~/.gazebo/
