Calculate the required heading (yaw) angle using the robot's current and target GPS coordinates: `ψ = atan2(ΔY, ΔX)`. Convert this global heading into a robot-centric command. For a differential drive robot, the orientation error is the difference between this desired heading and the robot's current compass/yaw reading. Use a proportional controller to adjust wheel velocities to minimize this error until the robot faces the target, then drive forward. Sensor fusion (GPS, IMU) is key for accuracy.
