    摘要: A pedometer navigator system has an Euler Angle Measuring Subsystem (EAMS) coupled to a body frame provides Euler angles of a fixed coordinate system with respect to a navigational coordinate system. Left and right sensors are mounted on a surveyor's feet. An SBPMS (short baseline position measuring subsystem) provides a left vector {right arrow over (&rgr;)}leftp and a right vector {right arrow over (&rgr;)}rightp characterizing the position of the sensors with respect to the SBPMS coordinate system origin. A computer means responds to the Euler angles and left and right vector and determines an interval during which the left or right foot is stationary, and providing a transition vector referenced to the earth fixed navigational coordinate system. A navigation algorithm adds each transition vector to the previous present position of the navigation reference system to obtain a next present position of the position measuring subsystem.

    摘要: A real-time high accuracy position and orientation system (RT-HAPOS) system for a vehicle, such as an aircraft, comprises a global navigation satellite system (GNSS) receiver disposed on the vehicle and an integrated inertial navigation (IIN) module disposed on the vehicle. The GNSS receiver generates GNSS position data indicating approximate positions of the vehicle during a data acquisition period in which the vehicle is moving. The IIN module executes a real-time kinematic (RTK) algorithm during the data acquisition period to generate output position data indicating positions of the vehicle at a greater precision than the GNSS position data, based on the GNSS position data, inertial measurement data acquired on the vehicle during the data acquisition period, and a set of virtual reference station (VRS) observables received during the data acquisition period from a remote source external to the vehicle, where the VRS observables are based on the GNSS position data.

    摘要: A quasi tightly coupled (QTC) aided INS (AINS) process has an inertial navigator system with a loosely-coupled AINS Kalman filter that constructs INS-GNSS position measurements, a GNSS position engine that computes a position fix from observables and an externally provided a priori position and position VCV matrix. An INS position seeding process in which the externally provided a priori position to the GNSS position engine is an antenna position computed from the INS position and attitude solution. An observable subspace constraint (OSC) process computes an OCS matrix that suppress the components of the GNSS position error due to a poor geometry in the GNSS position solution in the IG position measurement constructed by the AINS Kalman filter and that multiplies the OSC matrix and the IG position measurement and measurement model matrix to suppress uncorrected component of the GNSS position error in the IG position measurement and measurement model.

    摘要: The invention comprises a survey pole having a survey pole bottom end, with a position-transducer coupled to a survey pole top end. A ground contact spike is on the bottom end. The survey pole uses an AINS as a combined tilt and heading sensor. The AINS provides heading and Euler angle outputs characterizing the tilt of the survey pole. The heading and Euler angle outputs are used by a computer and program to perform position transfers from a position-transducer at the pole top end to the GCZVI switch or spike on the ground using a set of position offset or transfer equations. The position-transducer is either a GNSS or an RTS serving as a position-transducer. The transfer of the position data from the position of the position-transducer provides the earth referenced or grid referenced position of the spike at the survey pole survey bottom end.
