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.

Radio Frequency-Based Relative Navigation
2012For distributed systems in space, knowledge of the relative position and velocity is required to maintain the relative geometry of the satellites within certain boundaries. This knowledge can be obtained using an autonomous relative navigation system based on radio frequency (RF) signals. The design aspects of such a system are detailed in this chapter.

Vision based terrain relative navigation sensor
2015 International Conference on Trends in Automation, Communications and Computing Technology (I-TACT-15), 2015Space field has witnessed vigorous change due to evolution of image processing. For precise spacecraft navigation and landing, high end image processing algorithm has to be executed in real time. In this paper, vision based in plane relative positioning and velocity sensor is discussed for precise landing.
