What is TDOA?
One of the most commonly used positioning methods in UWB positioning technology is TDOA. The UWB positioning tag sends a UWB signal to the outside world, and all nearby UWB anchors will receive the wireless signal. If two UWB anchors receive the signal, the distance between the tag and the two anchors is different. Then the time points when the two base stations receive the signal are different.
The distance between the tag and different UWB positioning anchors is different. The time nodes at which different base stations receive the same label signal are different. The principle of SKYLAB TDOA positioning is to use the time difference of signals received by multiple base stations to determine the position of the tag.
