LuPNT: Open Source Simulator for Lunar PNT

With Guillem Casadesus Vila, Prof.Gao (Stanford University)

The growing focus on missions to the Moon necessitates reliable Positioning, Navigation, and Timing (PNT) services in cis-lunar space. We are developing a comprehensive, open-source simulation framework to address the growing research need in this field. Implemented primarily in C++ for computational efficiency, the simulation core employs an event-based architecture to model asynchronous onboard applications and inter-satellite communication. The framework also includes Python bindings to facilitate rapid algorithmic development and user interaction.

The simulator is under active development, is available here
