Positioning technology has been widely infiltrated into national economy and social development in various fields. Outdoor positioning technology through GPS and other global navigation satellite system (GNSS ) has been very mature. However,indoor environment is closely related to people’s production and life,and there are lots of indoor location services in need. UWB can solve this kind of problem by strong penetration,anti-multipath and anti-interference ability. Based the principle,we carried out a serious of positioning tests. It shows the precision of UWB could be cm level.
