During June 2025, Dahun worked on the AVSLab/basilisk repository, delivering sun data integration and orientation measurement features to enhance sun-relative attitude awareness for spacecraft simulation. Using C++ and embedded systems expertise, Dahun implemented reading and storing sun position vectors in the inertial frame, extended message payloads to include sun incidence and spacecraft view angles, and ensured calculations only occurred when sun data was available. This approach improved robustness by preventing unnecessary computations and potential errors. The work deepened the simulation’s capability for attitude estimation and navigation, while clear code structure and formatting updates contributed to maintainability and data integrity.

June 2025 monthly summary for AVSLab/basilisk: Delivered Sun Data Integration and Orientation Measurements to enhance sun-relative attitude awareness and orientation analysis. Implemented reading sun position data in SpacecraftLocation, added an input message for sun data, and stored the sun position vector in the inertial frame. Extended AccessMsgPayload with sunIncidenceAngle and scViewAngle to capture sun incidence and deputy spacecraft orientation. Strengthened robustness by gating sun-angle calculations on the availability of sun data, preventing unnecessary computations when sun data is absent. These changes enable more reliable attitude estimation and downstream navigation features, with improved data integrity and maintainability.
