    摘要： A method for calibrating and updating a golf course position, yardage and measurement system for golf carts that utilize dead reckoning navigation, to avoid gradual buildup of error from components of the dead reckoning system as the golf cart is being driven on the course during play, for the purpose of aiding golfers in playing the course by displaying distance measurements between the golf cart and various course features of interest. In one embodiment, the method includes storing a map of the course golf cart path in the database of the cart navigation system, determining from a comparison of the golf cart position in the dead reckoning navigation system and the stored golf cart path whether the golf cart is on the cart path during at least a part of the play of each hole; and, if so, calibrating and updating the dead reckoning navigation system according to a correction of error in the indicated position of an icon representing the golf cart relative to the cart path on a display screen in the cart to restore the icon to the cart path. In another embodiment, the travel of the cart is compared to the meanderings of the cart path on the stored map by comparing the dead reckoning trajectory of the cart to sequences of segments along the cart path until a pathway trajectory is found that closely matches the trajectory of the golf cart; and then correcting the indicated position of the golf cart accordingly, by which to calibrate and update the dead reckoning navigation system.

    摘要： A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. Each fleet vehicle has an assigned time slot to transmit its reporting information over a communications network without interfering with transmissions from other vehicles in their own respective time slots. A timing control phase lock loop (PLL) provides precise time synchronization for timing corrections from a global positioning system (GPS) based time reference. A dual band full-duplex interface of the network has TDMA on one-half and broadcast on the other half. Microprocessor time processing units in components of the network perform precise clock synchronization. Space diversity performed on received vehicle transmitted messages avoids data corruption. Different vehicles have different periodic transmission intervals, by dynamically allocating the slots for various update rates. Auxiliary reporting slots enable prompt reporting of important data by the respective vehicle transmitters independent of the slower periodic transmission intervals.
