Cooperatively extending the range of indoor localisation [PDF]

open access: yes
Whilst access to location based information has been mostly possible in the outdoor arena through the use of GPS, the provision of accurate positioning estimations and broad coverage in the indoor environment has proven somewhat problematic to deliver ...

Feasibility study for the implementation of a passive ranging system for Low Earth Orbit satellites [PDF]

open access: yes
In this project, a feasibility study has been carried out to implement a specialised passive ranging system for satellites in the LEO orbital regime, based on a system previously developed for GEO, called Focusear. For this purpose, a simulator, Parasim,

Target localization method based on semi-definite relaxation with frequency difference of arrival

open access: yesDianxin kexue
The use of frequency measurements to achieve target positioning is characterized by low cost and high reliability. Using only frequency difference of arrival (FDOA) measurements, a precise localization method for static target position was proposed.
