During a three-month period, Sam Bhattarai developed and refined flight dynamics and simulation software for the ISSUIUC/MIDAS-Software and TARS-Controls repositories. He implemented an Extended Kalman Filter-based state estimation pipeline for rocket flight, integrating barometric and accelerometer data, aerodynamic models, and motor thrust profiles using C++ and advanced data structures. Sam corrected coordinate transformation logic to ensure accurate body-to-global reference mapping, improving downstream physics and rendering. He also prepared aerodynamic simulation data by adding motor lookup tables in CSV format, enabling robust validation of motor performance. His work demonstrated depth in aerodynamics, sensor fusion, and embedded systems engineering.

February 2025 (2025-02) - ISSUIUC/MIDAS-Software: Delivered a robust EKF-based rocket flight state estimation pipeline with enhanced initialization, state prediction and update logic, and integration of flight phases, aerodynamic data, and motor thrust models. Completed data-loading refinements, code refactors, and documentation to improve estimation accuracy, maintainability, and onboarding. Fixed build stability by resolving compilation issues and implementing the get thrust capability. Implemented a data-lookup optimization (array of structs) based on peer feedback to improve performance and clarity. Expanded documentation and code comments to support future maintenance and knowledge transfer.

Month: 2024-12 — Concise monthly summary for ISSUIUC/MIDAS-Software. Delivered a critical bug fix in the Body2Global coordinate transformation to correct the multiplication order and include the roll matrix, thereby ensuring accurate transformation from body coordinates to global coordinates. This correction stabilizes downstream usage in rendering and physics pipelines and prevents incorrect world positioning due to rotation handling.
