N2 - Recently, utilization of position information by global navigation satellite system (GNSS) is expected in various fields. However, it's difficult to show unambiguously accuracy since positioning accuracy varies by measurement environment. We bring sky view factor (SVF) to evaluation of positioning accuracy, and evaluate it positioning accuracy of long time data in the places where SVF are high or low. In place where SVFs is high, precise positioning accuracy is got continuously for 24 hours, and it is found that variation of positioning accuracy is little. On the other hand, in place where SVF is low, positioning accuracy greatly varies. As the result of analysis of multi pass, it is found that the variation is caused by multi pass and difference of number of visible satellite.
