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.

Vision Based Relative Navigation

, 2012
Vision is a key technology for the relative navigation of formation flying satellites especially when they operate in close proximity. Indeed, with a vision system the relative position and attitude (usually referred to in the machine vision literature as “pose”) of co-flying satellites can be extracted in real-time. This information can be used either

Relative Navigation

, 2012
Satellite formations are being considered for a large variety of current and future space missions including in-orbit inspection, SAR interferometry, magnetospheric observation and gravimetry. In the case of cooperative satellite formations, differential

Visual SLAM for Asteroid Relative Navigation

2021 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2021
This 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

, 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, 2006
The 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), 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.
