Katarina Mavric developed a GPS NavSatFix to Pose ROS node for the rsx-utoronto/rsx-rover repository, enabling robust rover localization by converting two GPS NavSatFix streams into a single synchronized Pose message. She implemented message synchronization between dual GPS subscribers, ensuring consistent pose estimation even with asynchronous data. Using C++ and Python, Katarina applied GPS geometry calculations and quaternion conversions to accurately compute both position and heading, integrating the resulting pose into the rover’s state estimation workflow. Her work focused on reliable data fusion and seamless downstream publishing, demonstrating a solid grasp of ROS, robotics, and real-time sensor integration within a production codebase.
