Oak Ridge National Laboratory (ORNL) has developed an ultrasonic ranging and data system (USRADS) and interfaced the system with several types of survey instruments. The system measures the time of flight of an ultrasonic chirp between the surveyor's backpack and fixed receivers to determine location. Survey data are transmitted from the backpack to a computer via an RF data link and logged into a data file. Thus far a gamma scintillometer and a Geonics EM31 terrain conductivity meter have been interfaced to the system. An x-ray fluorescence spectrometer is in the final stages of testing, and work is presently under way to interface a photoionization trace gas analyzer. Digital output devices are connected via RS232 interface, and analog output devices are digitized by an 8-bit analog/digital converter (ADC). Future interfacing of other instruments should be relatively easy since these data structures will include most types of instrument outputs. 4 refs., 5 figs.
