A system and method for controlling the navigation of surface based vehicle uses a route that is obtained by manually driving the vehicle over the route to collect data defining the absolute position of the vehicle at various positions along the route. The collected data is smoothed to provide a consistent route to be followed. The smoothed data is subsequently used to automatically guide the vehicle over the route.
142 Navigation and positioning system and method using uncoordinated becon signals US614093 1996-03-12 US5689270A 1997-11-18 David C. Kelley; Joseph Cisneros; Louis A. Greenbaum
A positioning system uses a multiplicity of commercial broadcast stereo FM radio signal transmitters, at known fixed locations, each of which transmits a beacon signal having a phase that is un-synchronized with the phases of the beacon signals of the other transmitters. All the beacon signals have a frequency approximately equal to a 19 KHz. A fixed position observer unit, positioned at a known location, receives the beacon signals from all the transmitters in the vicinity, determines their relative phases, and broadcasts data representing these relative phases. Mobile units, at unknown locations, receive these broadcast values, as well as beacon signals from at least three radio transmitters. Each mobile unit includes phase detection circuitry that detects the phases of the beacon signals at the mobile receivers current position. This is accomplished using a single radio signal receiver. A digital phase-locked loop, coupled to the radio signal receiver, generates a phase error signal for each beacon signal. The phase error signals are then used to compute a distinct phase value for each beacon signal. In the preferred embodiment, each mobile receiver includes a computer for computing its location based on the broadcast relative phase values and the detected phases. In yet another embodiment a common timing signal is provided to the fixed observer unit and to the mobile units in order to establish a common time basis throughout the positioning system, thereby facilitating determination of an initial position for each mobile unit.
143 System and method for enabling an autonomous vehicle to track a desired path US432563 1995-05-01 US5684696A 1997-11-04 Prithvi N. Rao; Dong Hun Shin; William L. Whittaker; Karl W.

A system and method for enabling an autonomous vehicle to track a desired path plans a continuous path to return to the desired path when the vehicle deviates from the desired path. The continuous path is determined based on the vehicle's position, the desired path, and a lookahead distance. The lookahead distance is the distance on the desired path within which the continuous path and the desired path converge. The lookahead distance may vary as a function of vehicle speed. In one embodiment of the present invention, the continuous path is determined as a quintic polynomial.
144 Outdoor movie camera GPS-position and time code data-logging for special effects production US380959 1995-01-31 US5642285A 1997-06-24 Arthur N. Woo; David S. Sprague
A GPS navigation receiver with a data output port for communicating a position estimate frame-by-frame and time codes in SMPTE format. The conventional date and time sentence output of the GPS navigation receiver is combined with a highly-accurate one pulse-per-second (.+-.one microsecond) to form a time-keeping base for the time code output. A data-logger records the position estimates with their corresponding time in time code format frame-by-frame in a database. The recorded position estimates are then used in special-effects post-production to direct the special-effects animation, modeling kinetics, etc., in a composite, final film or video.
145 System and method for using parabolic models to improve position estimates from a global positioning system US457960 1995-06-01 US5629855A 1997-05-13 Christos T. Kyrtsos; James W. Sennott; Adam J. Gudat; Dana A. Christensen; Douglas W. Friedrich; Darrell E. Stafford
Systems and methods allow for the accurate determination of the terrestrial position of an autonomous vehicle in real time. A first position estimate of the vehicle 102 is derived from satellites of a global positioning system and/or a pseudolite(s). The pseudolite(s) may be used exclusively when the satellites are not in the view of the vehicle. A second position estimate is derived from an inertial reference unit and/or a vehicle odometer. The first and second position estimates are combined and filtered using novel techniques to derive a more accurate third position estimate of the vehicle's position. Accordingly, accurate autonomous navigation of the vehicle can be effectuated using the third position estimate.
146 Accurate position measuring system US414588 1995-03-31 US5617100A 1997-04-01 Masami Akiyoshi; Yuji Mitsunaga
An accurate position measuring system includes a communication satellite, a position measuring satellite, a position reference station, a network management station and a position measuring device. The communication satellite performs data communication. The position measuring satellite transmits position measurement data necessary for a position measurement calculation. The position reference station receives the position measurement data from the position measuring satellite and calculates positional error information. The calculated positional error information is transmitted to a network management station. The network management station collects the positional error information transmitted from the position reference station and transmits the collected positional error information to the communication satellite. The position measuring device receives the position measurement data from the position measuring satellite and calculates its current position. The position measuring device further receives the positional error information transmitted from the network management station through the communication satellite and corrects the calculated position information by means of the received positional error information.

151 Golf information and course mangement system US236139 1994-05-02 US5524081A 1996-06-04 Benjamin J. Paul
A golf information and management system utilizing the Global Positioning System, a satellite based, radio navigation system where clocks signals are transmitted. This satellite system provides at least four satellites (2) "in view" at all time. A golf cart (12) or player receives the signals from the four satellites, compares the clocked signals and an on-board computer reads the clocked signals and determines the position, in three dimension, of the receivers (velocity of the receivers is also available). There is a fixed base location (8) on the golf course that also receives the satellite signals and transmits a differential correction signal, via another channel, to the golf cart or player, where the computer determines the position of the cart or player to within a yard. The computer may be pre-loaded with golf course information, such as pin position, hazard positions, etc., where the computer via a graphical display (18) communicates to the player exact distances to the pre-loaded known physical features of the golf course, and displays information needed by the player to determine his next shot, including a video presentation of a golf pro's suggestions. In addition, the cart may communicate with the base station where the base station can track each cart or player on the course. With such information, detecting slow players to allow better course management, and also allows the base station to output information to a cart to show the players ahead so as not to hit into other groups and to send messages to carts to urge faster play to send out other type messages.

A method and computer program for determining an error factor for a differential global positioning system is disclosed as well as a method of tracking a vehicle. In determining the error factor, estimated positional data is transmitted from a GPS via GPRS to a server. Since the GPS signals are being transmitted from a vehicle travelling along a known route, i.e. a road or rail track, the data can be matched to the route and a correction factor calculated. The error factor is then transmitted to differential GPS devices. For vehicle tracking a global positioning system sends, via GPRS, data a regular intervals relating only to its position.
