Recent regulatory incentives (E911) and numerous location-based services and applications currently require accurate urban and indoor positioning ? challenging environments for GNSSes. This article investigates a means for enhancing positioning through the use of signals-of-opportunity based on the orthogonal frequency division multiplexing modulation. The authors describe the use of digital video broadcast-terrestrial signals to develop and test a pseudorange estimation method employing real signals and presents testing results that confirm previously identified theoretical results.
