ABSTRACT:
A real time geophysical survey system and method. The system comprises a base station, one or more data acquisition vehicles, and a global positioning satellite network. The base station is provided with a computer, radio communication equipment, and means for determining from signals of the satellite network the position of the base station. The data acquisition vehicles are each provided with geophysical survey instrumentation, radio communication equipment, an acquisition vehicle positioning display, and means using signals of the satellite network to calculate at least an approximate horizontal position of the data acquisition vehicle. During a survey, by periodically polling each data acquisition vehicle, the base station determines the location of each data acquistion vehicle and accurately tracks its position, both with respect to the base station and with respect to a preselected survey pattern over the geographic area to be surveyed. The base station transmits signals to each data acquisition vehicle positioning display so as to guide the data acquisition vehicle along the preselected survey pattern. As the survey progresses, data representing geophysical measurements taken by the geophysical survey instrumentation on each data acquisition vehicle is periodically provided in synchronization with data about the position of each data acquisition vehicle to the base station computer. The geophysical data is then correlated in real time with the position of each data acquisition vehicle and displayed for evaluation at the base station.
