1. A unit configured to provide acceleration, velocity, and position information for one or more points on a vehicle, said unit comprising:

  • an integrated global positioning satellite system (GPS)/inertial navigation system (INS); and

    at least one remote velocity sensor, said sensors comprising three orthogonal accelerometers, and a digital signal processor configured to receive signals from said accelerometers, said sensor mounted at a location on the vehicle where acceleration, velocity and position are to be determined, data from said sensor to be slaved to position, velocity and attitude data from said integrated GPS/INS to remove a drift in velocity data from said at least one remote velocity sensor, said unit configured to transform data from said sensor to a navigation frame utilizing a sensor frame to navigation frame attitude matrix, where the sensor frame is aligned with a vehicle body frame.
