Multiple-Links NLoS Error Evaluations for Geolocation Channel Modelling
Time Based (TB) localization by terrestrial cellular communications mobile radio as a complementation to Global Navigation Satellite Systems (GNSSs) has gained plenty of interests. Apart from multipath considered in standard communication channel models, the Non Line-of-Sight (NLoS) error due to an undetectable Line-of-Sight (LoS) path, defined as the additional propagation distance between the first detectable path and the Geometric LoS (GLoS), needs to be taken into account. In TB localizations, the range estimates from at least $3$ different links to Base Stations (BSs) are required to solve the $2$ dimensional navigation equation. In this paper we analyze the link-level NLoS errors based on a channel measurement campaign. It turns out to be, that the NLoS errors for difference links are i.i.d. processes.
