I'm trying to subscribe to the topic mavros/global_position/global using C++ and print the information on the screen. I followed this tutorial to create the subscriber node. However, the type of the mavros topic is sensor_msgs/NavSatFix I tried with cout because I don't know how it would be with ROS_INFO()
using namespace std;
void chatterCallback(const sensor_msgs::NavSatFix::ConstPtr& msg)
cout << *msg << endl;
int main(int argc, char **argv)
ros::init(argc, argv, "listener1");
ros::Subscriber sub = n.subscribe("/mavros/global_position/global", 1, chatterCallback);
But when I compile it and run it nothing happens. Does anyone know how can I do it? Also, how can I store the information ( longitude, altitude and latitude) that comes from the topic in a variable and use it in the program?
