Developed a GPS NavSatFix to Pose ROS node for the rsx-utoronto/rsx-rover repository, enabling robust rover localization by converting two NavSatFix streams into a single synchronized Pose message. The solution leveraged C++ and Python, utilizing GPS calculation helpers and quaternion conversion routines to compute accurate heading and position from dual GPS antennas. By synchronizing separate GPS subscriber streams, the node ensured consistent pose data for downstream localization and navigation components. The implementation integrated seamlessly with the existing rover state estimation workflow, focusing on code quality and reliable data fusion. This work addressed precise orientation estimation and improved overall navigation robustness.
