Self-Calibration for the Time Difference of Arrival Positioning [PDF]
Sensors, 2020 The time-difference-of-arrival (TDOA) self-calibration is an important topic for many applications, such as indoor navigation. One of the most common methods is to perform nonlinear optimization.

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.

Experimental measurement of time difference of arrival [PDF]
2016 17th International Radar Symposium (IRS), 2016 In this paper is described an experimental passive localization system based on SDR (Software Defined Radio) components. This system is designed to measure Time Differences of Arrival (TDOA) of radar pulses between two platforms. For a TDOA system, time error between the two receivers must be kept very low, which requires a very accurate way to ...

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.

Propagation Measurement on 2.5 mm NYAF Cable Using Load Matching and TDA [PDF]
E3S Web of Conferences, 2021 In this work, we propose measuring the propagation speed on the transmission medium in the form of a 2.5mm NYAF cable. The method used is load matching and time difference of arrival (TDA).
