A Review of Linear Multilateration Techniques and Applications
IEEE AccessIn multilateration, distances between an unknown location and several known points are used to determine the location of the unknown point. Papers on algorithms for multilateration, such as time of arrival (TOA), time difference of arrival (TDOA), and ...
