Research and development on mobile phone positioning technologies are gaining momentum due to the potential in location based services. Mobile location is estimated based on measurements from satellites and terrestrial base stations. Satellite measurements often available in rural and suburban areas are less or not available in dense urban and indoor areas. Thus, base station measurements play an important role in mobile positioning. In this paper, we present the highly detectable pilot (HDP) that is being standardized in 3GPP2 for cdma2000 1xEV-DO. HDP allows mobile to detect significantly more base stations, and thus provides much better accuracy in location estimate.
