520			_aDiscusses an integrated approach using GPS accelerometers and pseudolites, as well as showing some of the results obtained. Trials are underway in Nottingham to evaluate the approach, both in a controlled environment as well as on a bridge. The results show that the integrated approach has many advantages over GPS alone and can gather data at a very high rate. The results obtained are of both the magnitude of the deflections as well as the frequencies, both of which are important in obtaining knowledge about the health of the structure.
