OpenXNAV is an Open Source, modular toolkit for simulating high-fidelity pulsar X-ray events - designed to aid development and testing of Pulsar-based Autonomous Navigation (XNAV) Positioning, Navigation, and Timing (PNT) solutions.

This repository contains Bash scripts used to generate and analyze data from NASA's NICER mission, with a focus on the high-energy X-ray pulsar PSR B0531+21.

Pulsar timing analysis project using Vela photon event data: period detection, epoch folding, and a simplified XNAV demonstration. The approach is applicable to the tasks of telemetry, IoT and monitoring of complex systems.
