Visual SLAM for Asteroid Relative Navigation
2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2021This paper focuses on the application of visual SLAM for the purpose of precise autonomous navigation around an asteroid. We develop a factor graph-based approach allowing for incremental growth and fusion of sensor orientation measurements, Earth-relative inertial position measurements, as well as in-situ monocular camera imagery-based measurements ...

Autonomous Relative Navigation for Small Spacecraft [PDF]
, 2014 The thesis deals with the relative navigation between two small formation flying spacecraft. The inter-satellite distance is measured using locally generated radiofrequency ranging signals. Design considerations for the spacecraft and the relative navigation system are discussed as well as the estimation of the relative state.

Relative positioning for team robot navigation
Autonomous Robots, 2006The research presented in this paper approaches the issue of robot team navigation using relative positioning. With this approach each robot is equipped with sensors that allow it to independently estimate the relative direction of an assigned leader.

Relative navigation using pulsar signals
2011 International Conference on Wireless Communications and Signal Processing (WCSP), 2011Pulsar 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 Constrained SLAM for Robot Navigation
2019 American Control Conference (ACC), 2019This paper presents a relative-constrained SLAM formulation where partial a priori landmark information is built into the SLAM problem. Incorporating a priori relative constraints is motivated by the desire to avoid drawbacks of global constraints and to reduce uncertainty in the overall map and pose estimates.

Relative Navigation Technology
2018Relative navigation of spacecraft refers to determine the relative position and relative velocity between the two spacecraft (Yang et al. in Aerosp Shanghai (02):45–54 [1], Yang et al. in Aerosp Shanghai 27(2):38–45 [2], Shi et al. in Aerosp Control 28(6):43–48 [3]) by using spaceborne measuring equipment and combining with the relative motion equation

Liverpool has long been a major seaport and the present centre of nautical education at the Department of Maritime Studies of Liverpool Polytechnic has developed from the Liverpool Nautical College over several decades. Most of the students have a background of experience in merchant shipping and the port industry.

Spacecraft navigation and relativity
American Journal of Physics, 1985Special relativity relates measurements in a ‘‘moving’’ frame to measurements in a ‘‘rest’’ frame. Navigation, as it is performed in practice, uses neither pure a ‘‘rest’’ nor pure a ‘‘moving’’ frame, but instead measures distance in the fixed, Earth, frame and time in the moving, ship, frame.
