Can TDOA BS be used for positioning?
Only the TDOAs from other non-serving BSs could be used for positioning. The system estimates UE position based on TDOA-only but not hybrid TDOA, RTT, and DOA positioning. Therefore, the reduction in number of positioning measurements has a great impact on positioning accuracy.
Do TDOA localization systems need a stable network connection?
rove to be an important tactical advantage.On the other hand, it is worth noting that TDOA localization systems need at least three receivers (as opposed to minimum two for DF) with a stable network connection between them in order to transfer the d ta neede to perform the cross-correlation.Table 1.
Is TDOA a good ally for passive source localization?
)FlexiblePreferably NB signalsConclusionIn conclusion, TDOA localization can be an imp rtant ally for passive source localization. It is especially useful in cases in which we need to monitor possibly weak signals with lean, wideband, COTS antennas. The accuracy and precision of TDOA localization can easily reach tens to
What is TDOA localization?
on.1The Principles of TDOA Localization The conventional TDOA localization needs at least three receivers to locate a target in a 2D plane. The receivers need to be time-synchronized, usually through GNSS.One common way to estimate the TDOA of the signal arriving at two receivers is based on the cro
