Abstract
Abstract A real time geophysical survey system comprises a base srtation (12), one or more data acquisition vehicles (16, 18), and one or more fixed reference stations (14, 15). During a survey, by periodically polling a positioning transponder on sach vehicle, a positioning system of the base station tracks he position of each vehicle with respect to both the base tation and the fixed reference stations. Data regarding each rehicle's position are then provided to the base station computer, and the base station transmits signals to a positioning display aboard each vehicle so as to guide the vehicle along a preselected survey pattern. As the survey progresses, data representing geophysical measurements aken by instrumentation carried by each vehicle are beriodically transmitted to the base station computer. Such late 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.
