1. A location measuring device, comprising:
- a plurality of ultrasound transmitting units to sequentially transmit ultrasound signals to a moving object;
an information receiving unit to receive, from the moving object, inertia information related to a movement of the moving object; and
a location estimating unit to estimate a location of the moving object at a current time based on the inertia information and location information of the moving object at a time prior to the current time.

Abstract
Disclosed is a moving object and a location measuring device and method thereof that may transmit an ultrasound signal to the moving object through a plurality of ultrasound transmitting units, and may estimate a location of the moving object at a current time based on distance information of distances between the moving object and the plurality of ultrasound transmitting units measured based on the transmitted ultrasound, inertia information, and location information of the moving object at a time prior to the current time.
