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.

Open-source modular toolkit for simulating high-fidelity pulsar X-ray events. OpenXNAV is designed to aid development and testing of Pulsar-based Autonomous Navigation (XNAV) Positioning, Navigation, and Timing (PNT) solutions. This is a flexible, cost-effective testbed to enable the next generation of XNAV solutions.

X-ray pulsar-based navigation and timing (XNAV) or simply pulsar navigation is a navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determine the location of a vehicle, such as a spacecraft in deep space. A vehicle using XNAV would compare received X-ray signals with a database of known pulsar frequencies ...

New XNAV Simulation Overview • Developed general simulation tool to study XNAV system performance in arbitrary scenarios – Leveraged SEXTANT experience, flight software, and simulation tools – Added XNAV capability to the actively developed GEONS Ground MATLAB Simulation (GGMS) tool: XNAV-Enhanced GGMS=XGMS

2023年4月9日 · This paper focuses on the advances of the key techniques supporting XNAV, including the navigation pulsar database, the X-ray detection system, and the pulse time of arrival estimation. Moreover, the methods to improve the estimation performance of XNAV are reviewed.

This paper investigates the performance of XNAV in Earth and lunar regimes using a new high-fidelity XNAV analysis tool that builds on tools developed for SEXTANT and uses recent updates to the Goddard Enhanced Onboard Navigation System flight software.
