Satellite placement also matters. If the satellites are clumped together in one part of the sky, their rings intersect at very shallow angles. This creates a wide, blurry area of uncertainty around the true position. GPS engineers call this Geometric Dilution of Precision (GDOP). Good geometry means satellites spread across the sky, so that their rings cross at sharp angles and produce a tight, high-confidence intersection point. Your phone's GPS chip automatically selects the best combination of visible satellites to minimize GDOP.，这一点在软件应用中心网中也有详细论述
