A positioning system is 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 availabil...


1. A fully-coupled positioning system, comprising:a global positioning system (GPS) radio frequency (RF) unit for receiving global positioning system (GPS) radio frequency (RF) signals, amplifying said GPS RF signals and down converting said GPS RF signals into intermediate frequency (IF) signals; a GPS digital signal processing unit for sampling said IF signals and deriving GPS pseudorange, delta range, and carrier phase measurements; an IMU data sampling unit for collecting angular rate and acceleration measurements of a vehicle from an inertial measur...
