Abstract
Provided are an apparatus and method for estimating a location of the terminal using multiple location estimating schemes. The apparatus and method may estimate the location of the terminal more accurately by controlling initial conditions for a plurality of location estimating units, for example, a start time for estimating locations, initial parameters for location estimating schemes, and the like.
Claims22
An apparatus for estimating a location of a terminal using multiple location estimating schemes, the apparatus comprising:
- a location estimating module configured to estimate first locations of a terminal, based on a magnetic field affecting the terminal, using a plurality of location estimating units configured to estimate the first locations using a plurality of location estimating schemes;
- a location determining unit configured to determine a second location of the terminal based on the estimated first locations of the terminal;
- and
- an initial condition controlling unit configured to
- receive a result of estimating the location of the terminal from an i−1TH location estimating unit, among the plurality of location estimating units, i being a number of one of the plurality of location estimating units,
- determine whether the received result satisfies a predetermined condition, and
- start estimating the location of the terminal, using an iTH location estimating unit, among the plurality of location estimating units.
