    Abstract: A processing method for motion measurement, which is adapted to apply to output signals proportional to rotation and translational motion of a carrier, respectively from rate sensors and acceleration sensors, is more suitable for emerging MEMS rate and acceleration sensors. Compared with a conventional IMU, the processing method utilizes a feedforward open-loop signal processing scheme to obtain highly accurate motion measurements by means of signal digitizing, temperature control and compensation, sensor error and misalignment calibrations, attitude updating, and damping control loops, and dramatically shrinks the size of mechanical and electronic hardware and power consumption, meanwhile, obtains highly accurate motion measurements.

    Abstract: A filtering mechanization method is provided for integrating a Global positioning System receiver with an Inertial Measurement Unit to produce highly accurate and highly reliable mixed GPS/IMU position, velocity, and attitude information of a carrier. The GPS filtered position and velocity data are first individually used as measurements of the two local filters to produce estimates of two sets of the local state vector. Then, the estimates of the two sets of local state vectors are mixed by a master filter device to produce global optimal estimates of master state vector including INS (Inertial Navigation System) navigation parameter errors, inertial sensor errors, and GPS correlated position and velocity errors. The estimates of the two sets of local state vector and master state vector are analyzed by a GPS failure detection/isolation logic module to prevent the mixed GPS/IMU position, velocity, and attitude information from becoming contaminated by undetected GPS failures.

    Abstract: A positioning method and a system are disclosed for measuring a position of a vehicle on land, air, and space, using measurements from a global positioning system receiver and an inertial measurement unit. In the present invention, an integrated Kalman filter processes the all-available measurements of the global positioning system: pseudorange, delta range, carrier phase, and the solution of an inertial navigation system. The integrated Kalman filter is a multi-mode, robust kalman filter, in which optimal integrated mode is selected based on the measurement availability and filter stability. The high accurate solution of the inertial navigation system, which is corrected by the Kalman filter, is used to aid on-the-fly resolution of the carrier phase integer ambiguity of global positioning system in order to incorporate the carrier phase measurements into the Kalman filter, and to aid the carrier phase and code tracking loops of the receiver of the global positioning system to improve the receiver jamming and high dynamic resistance.

    Abstract: An aircraft rudder command system for allowing a pilot to directly input a sideslip command for yaw-axis control through use of the rudder pedals is disclosed. The aircraft rudder command system includes a pedal input device for receiving a pedal input signal indicative of pilot rudder pedal input, a signal-receiving device for receiving feedback signals indicative of the current state of aircraft operation, a command generator system responsive to the pedal input signal and at least one of the feedback signals for generating a sideslip angle command, command limiting means for generating a limited sideslip angle command, and a feedback control system for transmitting a sideslip control rudder command to a rudder actuation system. The rudder actuation system causes the rudder to move in such a manner so as to produce an actual aircraft sideslip angle which follows the limited sideslip angle command. The aircraft rudder command system may also include a sideslip estimator. The sideslip estimator includes a component for receiving an airmass sideslip signal, a sideslip rate estimator for generating a sideslip rate estimate signal, and a complementary filter for synthesizing a sideslip angle estimate signal from the airmass sideslip signal and the sideslip rate estimate signal. The rudder actuation system, in turn, causes the rudder to move in such a manner so as to cause the sideslip angle estimate signal to follow the limited sideslip angle command.
