A real time geophysical survey system and method. The system comprises a base station, one or more data acquisition vehicles, and one or more fixed reference stations. The base station is provided with a positioning system, suitable survey instrumentation, a computer, and radio communication equipment. The data acquistion vehicles are each provided with a positioning transponder, a positioning display, suitable survey instrumentation, and radio communication equipment. During a survey, by periodically polling each vehicle\s positioning transponder, the base station positioning system tracks the position of each vehicle with respect to both the base station and the fixed reference stations. Data regarding each vehicle\s position are then provided to the base station computer, and the base station transmits signals to the positioning display aboard each vehicle so as to guide the vehicle along a preselected survey pattern. As the survey progresses, data respresenting geophysical measurements taken by instrumentation carried by each vehicle are periodically transmitted to the base station computer. Such data are then correlated in real time with the position of the vehicle and with data collected at the base site, and then output for evaluation by the base station computer.
