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), 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.

Robust adaptive terrain-relative navigation
2014 Oceans - St. John's, 2014Terrain-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 ...

Journal of Navigation, 1974
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.

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

Relative Navigation of Air Vehicles
Journal of Guidance, Control, and Dynamics, 2008This paper derives the full equations of motion for relative navigation of air vehicles. An extended Kalman filter is used for estimating the relative position and attitude of two air vehicles designated leader and follower. All leader states are assumed known, whereas the relative states are estimated using line-of-sight measurements between the ...
