Worked on tudat-team/tudatpy, delivering six features over two months focused on improving modularity, maintainability, and data integrity in astrodynamics workflows. Refactored core architecture by introducing modular submodules for dynamics, environment setup, and observations, enabling clearer code ownership and easier future parameterization. Enhanced time handling and observation utilities with robust interpolation error management, new RMS and mean residual calculations, and configurable result printing during propagation and fitting. Applied Python and C++ for scientific computing, leveraging CMake and Pybind11 for build and integration. The work reduced log noise, stabilized APIs, and laid a foundation for safer, faster feature development and refactoring.

Nov 1, 2024Month: 2024-11 | Repository: tudat-team/tudatpy Key features delivered: - Robust Time Handling and Observation Data Utilities: consolidated major time handling improvements across observations, including robust time interpolation error handling for frequency transmission; new RMS/mean residual calculations; retrieval utilities for time bounds and link end IDs in observation collections; added Time.to_float; refactored observationFilter; updated defaults for integrated_observation_handling. Commits: c511dc4505e1200e76dee6ddfd019b7c9eda87d5; f8693424fe5779346250b0b18382f99d35d79c0a. - Warning Control and API Cleanup for Observation Set Splitting: improves handling of warnings during observation set splitting: prevents redundant warnings when splitting sets with filtered observations; introduces printWarning API to control warnings; aligns signatures with print_warning and updates related residual computation signatures. Commits: 3827c853538d92b380c93cf819a22c78ce6aebe8; 4054fd14369e9ebc83628e62a786de6b07cc1fc2. - Configurable Result Printing Frequency in Propagation and Fitting: adds controllable output frequency during propagation and fitting: excludes first/last hour from observation time generation for robust fitting; adds results_print_frequency parameter to the best-fit-to-ephemeris; enables configurable print frequency during propagation; includes minor cleanup. Commits: 4de5044030ed291b11f2e1f9d7ab4334cd7748ea; 1d7b56352ad77a0af7280000d481cb77a48c13db. Major bugs fixed: - Reduced redundant warnings when splitting single observation sets with filtered observations; stabilized residual computation signatures; updated split_observation_set arguments for better usability. Overall impact and accomplishments: - Enhanced data integrity and reliability of time-based observations, reduced log noise, and enabled configurable, interpretable output during propagation and fitting. This supports more accurate orbit determination, easier debugging, and a cleaner API surface. Technologies/skills demonstrated: - Python-based scientific computing, API design and cleanup, time-series/data handling, RMS/mean residual analysis, time interpolation robustness, and configurable logging/printing for robust fitting workflows.
