Broadband acoustic source transmissions recorded on Seagliders at ranges up to 700 km are used to estimate subsurface glider position. Estimates of a posteriori errors ranged from 78105-m rms and from 9.111.6-cms rms for glider position and velocity, respectively. Data residuals were on the order of 50-m rms. These results demonstrate the potential for more precise long range underwater acoustic navigation, with the understanding that the navigation and the ocean sound speed and currents be jointly determined.
