Relative Navigation of Air Vehicles

Journal of Guidance, Control, and Dynamics, 2008
This 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 ...

Relative indoor spatial tracking and navigation

International Journal of Wireless and Mobile Computing, 2015
Indoor Positioning and Indoor Navigation IPIN is a topic of research and industrial interest. Towards the direction of indoor positioning there are two main alternatives: absolute and relative. Absolute positioning requires infrastructure whereas relative positioning is based on dead reckoning and does not require any infrastructure.

Multispectral Sensing for Relative Navigation

2019
A 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.

Relative navigation with passive underwater acoustic sensing

2015 12th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2015
Navigation in an underwater environment is challenging because global positioning system (GPS) is not available due to the rapid attenuation of electro-magnetic waves in water. Acoustic baseline systems have been good alternatives to GPS for correcting dead-reckoning errors. However, their deployment and recovery generally require much effort.

Mars Rendezvous Relative Navigation Implementation for SINPLEX

AIAA/AAS Astrodynamics Specialist Conference, 2014
In this work the development of the navigation solution for the Mars rendezvous scenario for the SINPLEX system is described. SINPLEX is a miniaturized integrated navigation system comprised of an IMU, laser range finder, navigation camera and star tracker.

Fault Tolerant Relative Navigation Using Inertial and Relative Sensors

AIAA Guidance, Navigation and Control Conference and Exhibit, 2007
Many 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 ...

Operational Aspects of JTIDS Relative Navigation

Journal of Navigation, 1988
This paper represents a follow-up of work previously reported at an Ordinary Meeting of the Institute and published in the Journal in May 1986 under the title ‘Navigational Aspects of JTIDS’.Technical studies on JTIDS for the airborne applications are being directed by the Royal Aircraft Establishment (RAE), Farnborough and by the Admiralty Research ...

Principles of JTIDS Relative Navigation

Journal of Navigation, 1996
This 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.

A relative navigation system for formation flight

IEEE Transactions on Aerospace and Electronic Systems, 1997
A relative navigation system based on both the Inertial Navigation System (INS) and the Global Positioning System (GPS) is developed to support situational awareness during formation flight. The architecture of the system requires an INS/GPS integration across two aircraft via a data link.

A relative navigation system for vehicle platooning

SICE 2001. Proceedings of the 40th SICE Annual Conference. International Session Papers (IEEE Cat. No.01TH8603), 2002
The paper is concerned with a relative navigation system. The previous reported relative navigation system designed for formation flight is applied to vehicle platooning. This system is based on both GPS (Global Positioning System) and millimeter-wave radar. This approach includes a federated Kalman filter.
