Abstract
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;)} and a right vector {right arrow over (&rgr;)} 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.
