Presented is a position-measuring device using UWB antenna, the position-measuring device distinguishing measurement targets positioned indoors from measurement targets positioned outdoors on the basis of UWB signals received from a plurality of UWB antennas. The presented position-measuring device includes: a first UWB antenna; a second UWB antenna; a third UWB antenna; a signal processing module which outputs a signal received from the first UWB antenna and a UWB signal received from at least one among the second UWB antenna and the third UWB antenna; and a position-measuring module which measures the position of the measurement target on the basis of the UWB signals output from the signal processing module.

Position-measuring device using UWB antenna

A method for providing a location tracking service on the basis of context-aware information of a location tracker, according to the present invention, transmits a signal while changing a communication method by classify a situation as an emergency situation and a normal state which is a non-emergency situation according to the context-aware information of the location tracker, such that it is possible to use power consumption reduced by a low-power communication method in the normal state, and in case of the emergency situation, to safely handle the emergency situation through a sufficient power communication method.
