Ongoing and planned developments

Below is a (non enirely comprehensive) list of features and functionalities that are under active development, or or our near(ish)-term wishlist. For some of them, the requied development would be ython-only. If you’re interested in the status of these points, in contributing, or in proposing additional ones, please feel free to contact us!

  • Extension of Tudat estimation functionality for real tracking data analysis, with a focus on planetary missions

    • Reading typical radio tracking data files (ODF, TNF, TDF) into Tudat-compatible data structures (Python?)

    • Linking JPL Horizons and Minor Planet Center databases to Tudat environment, to make setup of planetary mission scenarios easier, both will use the astroquery package (Python)

    • Adding models for media corrections for radio tracking (troposphere, ionosphere, corona)

    • Implement sparse matrices for partials matrices

  • Adding better functionality to automate the plotting of numerical propagation results, including easier access to specific dependent variables (Python)

  • Linking SGP4 propagator to Tudat (Python?)

  • Use a dedicated Time object to represent time (rather than just a double)

  • Linking the preliminary mission design module to the numerical propagation, including automated differential corrections

  • Supporting events during the propagation (i.e. modify models when a specific condition is met)

  • Implementing regularized propagators (e.g. Dromo)

  • Implement detailed radiation pressure models

  • Extend CR3BP propagation and mission design functionality (including differential correction to account for perturbations)

Contributor list

Below, there is a list of contributors to Tudat. Mostly, these have been staff and students of TU Delft who have worked on Tudat as part of their research project(s) and/or as TAs. Many of them have put a lot of their free time and research time into making Tudat what it is. If you think your name is missing here, please let us know!

Tudat Alumni Hall-of-fame

  • Kartik Kumar - For starting it all, developing numerous core features, and leading the project through the crucial first few years with huge passion and commitment

  • Jacco Geul - For supporting Tudat for the duration of his Ph.D. project, resolving more bugs and answering more questions than we can count and professionalizing the setup of the project

  • Jeroen Melman - For helping to build up the Tudat project in its very first years with code development and project setup, without which it may never have survived
