发明名称 Method of localizing a moving body
摘要 A method of localizing a moving body, by which the magnitude of parameters, which can give rise to bias errors, is estimated inversely from the difference between two locations of the moving body estimated by two different localization methods. Various quantities (position of sensors, propagation velocity of radiation, etc.), on the basis of which localization operations are carried out, can be corrected by using the magnitude thus estimated. The emission time of the radiation from the moving body can be estimated by the hyperbolic surface localization method and the spherical surface localization method can utilize the emission time thus estimated to localize the moving body. Further, localization errors caused by both localization methods can be estimated, so that it is possible to determine which localization method should be used to localize the moving body.
