Note: Outdoor GPS and RTK Navigation¶
You are probably here because the robot works indoors or in simulation, but field behavior is unstable, globally inaccurate, or much harder to reason about once GNSS enters the loop.
Likely First Answer¶
Start with GPS, RTK, and Outdoor Navigation in ROS 2.
If the Real Problem Is...¶
- weak state estimation architecture: Localization, State Estimation, and Frame Discipline
- poor sensor fusion setup: EKF Sensor Fusion for Robots
- multiple sensors disagreeing: Multi-Sensor Fusion Patterns
