With the advent of agile satellite missions, new solutions are needed to cope with frequently occurring maneuvers to fulfill the strict POD requirements imposed by scientific mission goals. The C++ software "Precise Orbit Determination for Complex and Agile Satellite Technology" (PODCAST) aims to create a flexible framework to investigate novel approaches related to POD and PBD of agile and non-agile satellites. PODCAST facilitates this by abiding by a modular concept for all core components needed for POD and thus ensures the complete interchangeability of algorithms and models in the development process. This study gives insights into the modular architecture of PODCAST and the underlying fundamental principles. The capabilities are demonstrated for a GNSS-based POD using simulated observations created for a Sentinel-3A reference trajectory. The obtained results indicate the accomplishable accuracy and precision for given measurement errors using the approaches presented in this work. We further showcase that PODCAST can serve as the foundation for future POD software development and suggest improvements that allow addressing of future mission-critical POD features. %@ 978-0-936406-32-9
