Adaptive extended Kalman filtering strategies for spacecraft formation relative navigation

Acta Astronautica, 2021
The relative navigation problem for spacecraft formation flying missions in near-Earth orbit is addressed here through the design of two unique adaptive extended Kalman filter algorithms.

Analytical Nonlinear Observability Analysis for Spacecraft Autonomous Relative Navigation

IEEE Transactions on Aerospace and Electronic Systems, 2022
Spacecraft autonomous relative navigation is widely required in the field of on-orbit services. In previous works, it has been shown that the monocular sequential images (MSIs) is a cost-effective autonomous relative navigation method. However, given the

A seasonally invariant deep transform for visual terrain-relative navigation

Science Robotics, 2021
Deep image transforms automatically learn stable structures that improve visual navigation for air and space robots. Visual terrain-relative navigation (VTRN) is a localization method based on registering a source image taken from a robotic vehicle ...

Synthetic-Aperture-Radar–Based Spacecraft Terrain Relative Navigation

Journal of Spacecraft and Rockets, 2022
A spacecraft terrain relative navigation system for Low Elevation Orbit satellites is presented relying on measurements obtained from a synthetic aperture radar (SAR) that are fused with inertial measurements and attitude determination system data in a ...

Optimal Maneuvering for Autonomous Relative Navigation Using Monocular Camera Sequential Images

Journal of Guidance Control and Dynamics, 2021
The use of monocular sequential images for relative navigation provides an efficient method for estimating the relative state of space non-cooperative targets, where the estimation accuracy is impo...

Neural Network Approach to Crater Detection for Lunar Terrain Relative Navigation

Journal of Aerospace Information Systems, 2021
Terrain relative navigation can improve the precision of a spacecraft’s state estimate by providing supplementary measurements to correct for drift in an inertial measurement unit.

GPS Based Relative Navigation

2012
The use of Global Positioning System (GPS) measurements provides the primary technique for determining the relative position of cooperative, formation-flying satellites in low Earth orbit. Similar to terrestrial applications, the relative navigation benefits from a high level of common error cancellation.

Relative navigation using pulsar signals

2011 International Conference on Wireless Communications and Signal Processing (WCSP), 2011
Pulsar navigation has shown its great potentiality in autonomous navigation for orbit satellite and deep space spacecraft. Relative navigation using pulsar signal has shown its benefit in recent years, and higher performance has achieved in some studies.

Relative navigation of fixed‐wing aircraft in GPS‐denied environments

Navigation, 2020
This work enables GPS-denied flight on fixed-wing UAS by accounting for fixed-wing-specific sensing requirements and using a methodology called relative navigation as an overarching framework.

Robust adaptive terrain-relative navigation

2014 Oceans - St. John's, 2014
Terrain-Relative Navigation (TRN) is a technique for localizing a vehicle in GPS-denied environments. TRN augments a dead-reckoned solution with continuous position fixes based on correlations with a pre-stored map. In underwater applications TRN accuracy on the order of 3m has been demonstrated, however convergence to incorrect solutions has been ...
