Navigational independent relative positioning system NIRPS
Proceedings of the IEEE 1997 National Aerospace and Electronics Conference. NAECON 1997, 2002Navigational Independent Relative Positioning System (NIRPS) uses the relation between inertial media (its own body) and non-inertial media (light) to provide information on the velocity (speed and direction) with which it travels in three-dimensional space.

Operational Aspects of JTIDS Relative Navigation
Journal of Navigation, 1988This 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 ...

Relative indoor spatial tracking and navigation
International Journal of Wireless and Mobile Computing, 2015Indoor 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.

Sonar-based iceberg-relative AUV navigation
2008 IEEE/OES Autonomous Underwater Vehicles, 2008AUVs have been operating under the ice for years. All of these systems have relied on combinations of dead-reckoning using inertial measurements, acoustic transponder networks, and/or velocity measurements from a Doppler velocity logger (both seafloor-relative and ice-relative) for navigation and control. These existing systems can be very accurate for

Decentralized Relative Navigation and JTIDS/GPS/INS Integrated Navigation Systems
1982Abstract : One contribution of this research is a deeper understanding of the stability and performance of community relative navigation, such as is currently implemented in the Joint Tactical Information Distribution System (JTIDS). Relative navigation in the JTIDS system is organized in a decentralized manner with the Kalman filter in each member ...

Traditional Methods on Relative Navigation of Small Satellites
International Conference on Recent Advances in Space Technologies, 2019This Paper is devoted to understand traditional relative navigation and models which are used for small satellites. Compare the taraditional relative navigations models and aproaches which are based on different sytems (Inertial Navigation Systems (INS ...

Real-Time Vision-Based Relative Navigation
AIAA Guidance, Navigation, and Control Conference and Exhibit, 2006This paper describes two vision-based techniques for the navigation of an aircraft relative to an airborne target using only information from a single camera fixed to the aircraft. By applying an Extended Kalman Filter (EKF) for relative state estimation, both the velocity and position of the aircraft relative to the target can be estimated.

Relative navigation in autonomous spacecraft formations
2016 IEEE Aerospace Conference, 2016Spreading of spacecraft formations and constellations made up by affordable platforms as cubesats poses the issue of technologically simple navigation subsystems, mandatory to exploit these missions. This paper describes solutions based on hardware that should be either already included or easy to accommodate on these platforms.
