Vision Based Relative Navigation
2012Vision 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

Journal of Navigation, 1972
The following discussion took place at an open session of the Technical Committee held at the Royal Aeronautical Society in London on 19 January 1972 with Mr. H. E. Smith in the Chair.The Chairman: Relative navigation has a wide connotation, but for the purpose of our discussion it may be applied firstly to aircraft management in the positive or ...

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.

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 ...

Multispectral Sensing for Relative Navigation
2019A relative navigation system based on multispectral sensing device, for non-cooperative rendezvous between a chaser and a target, as well as for the descent and landing on an asteroid, is presented. Firstly, the advantages of using a multispectral camera capable of detecting different spectral signatures are discussed.

Angles-Only Relative Navigation Activities during AVANTI
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2017This contribution addresses the realization of angles-only relative navigation systems as means to approach noncooperative target objects flying in low Earth orbits. Based on the recent in-flight experience collected during the AVANTI (Autonomous Vision Approach Navigation and Target Identification) demonstration, a critical comparison between ...

Fault Tolerant Relative Navigation Using Inertial and Relative Sensors
AIAA Guidance, Navigation and Control Conference and Exhibit, 2007Many emerging applications of space, ground, marine, and air vehicles require relative automated navigation with respect to other vehicles and objects. Disturbances in the environment may cause faults in relative navigation sensors. For sensors based on cameras or laser range finders, events as common as lighting changes, glint, or obstruction by ...

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.

Principles of JTIDS Relative Navigation
Journal of Navigation, 1996This paper describes one of the key features of the JTIDS/Link 16 tactical data-link, namely its relative navigation facility. A brief overview of the general features of the JTIDS system is given to provide the necessary background to the navigation aspects, and some mention is made of the message-exchange facilities.

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.
