    • A method of increasing location accuracy in an inertial navigational device (100) is described herein. The navigational device (100) generates real-time data to depict its location. The data comprises at least one of sensor data, motion data, and location data. The navigational device (100) transmits the real-time data to a second device (104) in a real-time fashion. The navigational device (100) receives an update message from the second device (104), based on a comparison of the real-time data generated by the navigational device (100) against a second set of data. The navigational device (100) adjusts its depicted location based on the update message in order to increase the location accuracy of the navigational, device (100). Alternatively, the navigational device (100), absent the second device (104), can compare the real-time data generated against the second set of data internally and adjust its depicted location accordingly.
    • 本文描述了在惯性导航装置(100)中提高定位精度的方法。 导航设备(100)生成实时数据以描绘其位置。 数据包括传感器数据,运动数据和位置数据中的至少一个。 导航装置(100)将实时数据以实时方式发送到第二装置(104)。 导航设备(100)基于由导航设备(100)生成的实时数据与第二组数据的比较,从第二设备(104)接收更新消息。 导航设备(100)基于更新消息来调整其描绘的位置,以便增加导航设备(100)的定位精度。 替代地,不存在第二设备(104)的导航设备(100)可以在内部生成的实时数据与第二组数据进行比较,并相应地调整其描绘的位置。
