Location technology is entering ever more deeply into our day-to-day lives. Growing market demand for location-based services (LBS) revolves the single premise: “Location everywhere, any time.” The requirement for seamless, ubiquitous positioning includes, of course, urban and indoor environments. Meeting this requirement will provide the cornerstone for a real “boom” in the location market. To realize the capability, location technology seems to evolve naturally towards the aggregation of several systems used in combination to provide accurate information to users. In addition, the market will require more and more reliability, for which SBAS may play a great role. The paper also shows how GNSS may be an key enabler for the more and more demanding network data rate of 4G networks. This can happen thanks to the new synchronization capability that GNSS can bring.
