Ultra-wideband technology uses nanosecond non-sinusoidal narrow pulses to transmit data, so it occupies a wide spectrum range and has high time resolution. The traditional positioning technology is to judge the position of an object according to the flight time or signal strength of wireless sinusoidal signals, but it is easily affected by multipath or external environment, and the positioning position has errors with large fluctuations and low positioning accuracy.

EHIGH constant ultra-high wideband precise positioning system adopts wideband narrow pulse communication technology (extremely high time resolution, which reduces the positioning error), multi-source data fusion (effectively improving the anti-interference ability of the positioning system) and time series signal processing technology (extracting the first arrival path signal in a strong multipath complex environment), so it can realize accurate positioning of the positioning target.
