LuNART-q: The LuGRE Quick Navigation Analysis and Reporting Tool

The Lunar GNSS Receiver Experiment (LuGRE) quick Navigation Analysis and Reporting Tool (LuNART-q) is a MATLAB-based platform developed by Politecnico di Torino for the Italian Space Agency (ASI) and in collaboration with NASA's SCAN program and Qascom S.r.l. Derived from a broader scientific framework for the LuGRE mission, it enables rapid visualization, validation and exploitation of GNSS data acquired in lunar and cislunar environments. LuNART-q automates telemetry parsing, analysis and post-processing of GNSS observables and I/Q batch analysis, navigation performance evaluation, and structured reporting. Twelve configurable "quick experiments", derived from LuGRE Science Definition Team Report objectives, produce experiment reports that can be consolidated into operation summary reports for immediate assessment. Visualization modules allow prompt analysis of signal availability, occultations, and receiver performance, while compliance with Ground System Working Group standards ensures interoperability. An open project based on LuNART-q will be released to allow the community to immediately explore LuGRE open data from the mission, fostering reproducibility, education, and collaborative research. By integrating predictive analysis, adaptive experiment execution, and reproducible reporting, LuNART-q provides an innovative framework that maximized the scientific return of the LuGRE mission and paves the way for companion software designed to support and advance scientific objectives in future missions.
