  • Method of increasing location accuracy in an inertial navigational device
    Patent number: 6615136
    Abstract: 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.

  • Device for use with a portable inertial navigation system (PINS) and method for processing PINS signals
    Patent number: 6577953
    Abstract: A first device (104) receives a first set of data from an inertial navigational device (100). The first set of data comprises at least one of sensor data, motion data, and location data, and is real-time output from the inertial navigational device (100). The first device (104) also receives a second set of data from a secondary source. The second set of data also comprises at least one of sensor data, motion data, and location data. The first device (104) generates an update message based on comparing the first set of data against the second set of data in order to improve location accuracy of the inertial navigational device (100). Optionally, the first device (104) can transmit the update message to the inertial navigational device (100).
