Dilution of precision 意味

WebDilution of Precision Metrics for Wireless LAN-based Indoor Location Systems 1.2 Summary The geometric strength of satellite congur ations inuences the precision of the Global Positioning System (GPS). If the satellites, that are visible to a re-ceiver, are close to each other the geometry is weak. That means, the position WebIt may be a duplicate , but it was said: "All the GPS receiver is doing, is multiplying the dilution of precision figure by the resolution of the device." I didn't catch that, what is the "resolution of the device"? gps; accuracy; nmea; Share. Improve this question. Follow
