    摘要: Embodiments of the invention provide a blending filter based on extended Kalman filter (EKF), which optimally integrates the IMU navigation data with all other satellite measurements tightly-coupled integration filter. This blending filter can be easily implemented with minor modification to the position engine of stand-alone GNSS receiver. Provided is a low-complexity tightly-coupled integration filter for sensor-assisted global navigation satellite system (GNSS) receiver. The inertial measurement unit (IMU) contains inertial sensors such as accelerometer, magnetometer, and/or gyroscopes Embodiments also include method for pedestrian dead reckoning (PDR) data conversion for ease of GNSS/PDR integration. The PDR position data is converted to user velocity measured at the time instances where GNSS position/velocity estimates are available.

    摘要: A system and method for controlling a navigation receiver is disclosed. A current position is determined using the navigation receiver and then the navigation receiver is placed in a power-save mode. The current position is updated using information from position sensors. The navigation receiver is temporarily placed in an active mode at intervals to determine an intermediate position. The current position is also updated using the intermediate position. The navigation receiver may be a GNSS receiver, a cellular receiver, a WiFi receiver, or another position-fixing device. The position sensors may be accelerometers, gyroscopes, electronic compasses or mapping data. A power-save controller controls the power-save or active mode of the navigation receiver. A sensor conditioning circuit pre-processes the data from the position sensors before providing the data to the power-save controller. During the power-save mode, an RF subsystem and/or a baseband subsystem of the navigation receiver may be turned off.
