DEVICE FOR USE WITH A PORTABLE INERTIAL NAVIGATION SYSTEM (PINS) AND METHOD FOR PROCESSING PINS SIGNALS

摘要

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).
