Localization algorithms for asynchronous time difference of arrival positioning systems [PDF]
EURASIP Journal on Wireless Communications and Networking, 2017 An asynchronous time difference of arrival (ATDOA) positioning system requires no time synchronization among all the anchor and target nodes, which makes it highly practical and can be easily deployed.

Time difference of arrival localisation exploiting all available time differences [PDF]
IET Radar, Sonar & Navigation, 2020 Time difference of arrival geolocation is re-analysed exploiting all available time differences, though sticking to closed-form algorithms based on the minimum number of time differences. The additional information is statistically utilised in a sound way. Error estimates for the resulting position and the Cramer-Rao lower bound are derived.
