Description: The main objective of UTD`s completed contract was to demonstrate the accuracy UTD POsition LOcator (POLO) system d for penetrometer applications. The contract work was accomplished in three phases. Phase I involved sub-scale refinement of the POLO sub-systems which included the design and testing of individual components of POLO. The objectives of Phase II were to integrate a prototype POLO unit and demonstrate its accuracy through laboratory tracking experiments. Phase III objectives included manufacturing and assembly of a full-scale POLO unit and demonstration of its accuracy under field conditions. The success criterion for the entire contract was to calculate the penetrometer tip position with 0.5% accuracy or better with respect to distance traveled both in laboratory and field tests. This criterion was satisfied in Phase II laboratory tests and in Phase III field tests at two different sites. With successful completion of the contract in September, 1994, UTD has embarked on a commercialization plan in order to make commercial POLO units available to DOE contractors and penetrometer users in a timely fashion.
