Abstract:	The Global Navigation Satellite system (GNSS) is experiencing an exponential growth of the consumer segment demand. Many applications emerged after the E- 911/E-112 regulations. Positioning needs to be carried out in all the environments covered by the wireless communication services, including the most constraining areas such as obstructed indoor environments. Different techniques have emerged already in the market claiming some navigation capabilities indoors. However, they usually have an accuracy of some tens of meters, at best. In some cases, with the deployment of pseudolites, indoor navigation shows decent performance, but there is still a question of whether GPS has a good enough signal structure for such applications in the first place. In this paper, measurement-based modeling results with the purpose of giving further insight on the real satellite-toindoor channel characteristics are described.
