I get somewhere between 4 to 6 satellites when mostly indoor or surrounded by tall buildings. When I am on an open freeway in my car, most I have gotten was 12 but average 6 to 8 in a clear day.

Besides getting more satellites, we need to look at the DOP value. GPSviewer shows this value. The lower the value, the more accurate your location is. This value is determined by how far the satellites you obtained are apart from each other. I don't know how they calculate it, just know that the lower the value the better.
