X-ray pulsar-based navigation method using one sensor and modified time-differenced measurement

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2017
X-ray pulsar-based navigation method using one sensor (XNAVO) could fix the position of satellites by sequentially observing X-ray pulsars at the cost of loading one X-ray sensor, which drops the demand on the loading capability of satellite and is feasible for practice.

A Novel Celestial Aided Time-Differenced Pulsar Navigation Method Against Ephemeris Error of Jupiter for Jupiter Exploration

IEEE Sensors Journal, 2019
Subjected to the current observation technology, the planetary ephemerides which are used to predict the positions of planets are not accurately known. For Jupiter exploration, ephemeris error of Jupiter will greatly degrade the performance of navigation system.

From theory to inference: New methods for probing the nanohertz Gravitational Wave sky with Pulsar Timing Arrays

Pulsar Timing Array (PTA) experiments aim to detect gravitational wave (GW) signals at nanohertz frequencies through pulsar timing, by characterising the timing delays they are expected to induce. Pulsars are incredibly stable, compact, fast-rotating objects with a collimated jet of radio emission, observed as a pulsating signal (lighthouse effect ...
