  • Publication number: 20140149034
    Abstract: Disclosed herein are an apparatus for integrating multiple rate systems and a method of operating an apparatus for integrating multiple rate systems. In the method of operating the apparatus, navigation information is calculated through an inertial measurement unit, and mean values and variances of initial state variables of the navigation information are set. Sigma points are calculated using the mean values and the variances. The mean values are time-propagated until measurement information is input through a Global Positioning System (GPS). When the measurement information is input, the sigma points are time-propagated at intervals of a frequency of the measurement information. Variances are calculated using the time-propagated sigma points. The navigation information is updated using the time-propagated mean values, the calculated variances, and the measurement information.

  • Publication number: 20100265092
    Abstract: The present invention relates to a location measuring method using an access point, and an apparatus using the same. According to the present invention, a location of a terminal is estimated by using a signal strength received from an access point installed at a known position in a wireless network, and location of the access point installed at an unknown position is estimated by using a signal strength received from the access point installed in the unknown position and estimated location information of the terminal. In addition, a location of the terminal is finally calculated by using estimated location information of the access point installed at the known position. As described, the location of the terminal is determined by using estimated location information of an AP that is randomly installed by a user (that is, installed at an unknown position), and therefore a location of an AP installed in an area where it is difficult to measure and availability of location measurement can be improved.
