METHOD AND SYSTEM FOR PROCESSING PULSE SIGNALS WITHIN AN INERTIAL NAVIGATION SYSTEM

摘要

A method and system (100) for processing pulse signals within an inertial device is provided. The inertial device may have inertial sensors, such as accelerometers (110, 112, 114) and gyroscopes (104, 106, 108). The inertial sensors may output signals represen tative of a moving body's motion. The signals may require correction due to imperfections and other errors of the inertial sensors. The inertial device may receive signals from the inertial sensors and process the signals on a signal-by-signal basis so that when processing the signals, the inertial device at least recognizes which sensor output a signal and when the signal was output. The inertial device may then correlate signals that were output from the inertial sensors at selected times in order to transform the signals into desired navigational frame of reference.
