Hello, im working on a navigation system.
I am using two instances of ekf filter from robot_localization package. I am obteinig that in the "odom" frame, i receive the gps signal with the odometry_map signal with a good performance, the signals are near enough to the robot whe it is static.
But when i visualice what is happening in the "map" frame, the robot is constantly moving around the ground, and the gps, and the /odometry/global signals are moving together with the robot.
So, the idea that i have is that the "odom -> map" trasnform frame is constantly moving alone. Why i am getting that? Is it becuase the GPS signal ? I am watching that sometimes the robot move in a area that more than 3m of error, which is usually the average gps error.
