Location errors in time of arrival (TOA) and time difference of arrival (TDOA) systems [PDF]
, 1977 It is shown that the covariance matrix of object location errors is identical for time of arrival (TOA) and time difference of arrival (TDOA) systems if the inverse of the covariance matrix of TOA (TDOA) errors is used as a weighting matrix. Also, with this weighting the location errors statistics do not depend on the particular difference pairs in the

On the Geolocation Bounds for Round-Trip Time-of-Arrival and All Non-Line-of-Sight Channels
EURASIP Journal on Advances in Signal Processing, 2007 The development of future geolocation systems requires a fundamental understanding of the importance of various system parameters, such as the number of sensors, the SNR, bandwidth, and channel conditions. We consider the bounds on time-based geolocation

Hybrid TOA/AOA Approximate Maximum Likelihood Mobile Localization
Journal of Electrical and Computer Engineering, 2010 This letter deals with a hybrid time-of-arrival/angle-of-arrival (TOA/AOA) approximate maximum likelihood (AML) wireless location algorithm. Thanks to the use of both TOA/AOA measurements, the proposed technique can rely on two base stations (BS) only ...

Decawave UWB Clock Drift Correction and Power Self-Calibration
Sensors, 2019 The position accuracy based on Decawave Ultra-Wideband (UWB) is affected mainly by three factors: hardware delays, clock drift, and signal power. This article discusses the last two factors.
