Abstract:

Up to now, the accuracy for estimation of GNSS statics measuring baseline is usually using from machine's catalog with mD=a+b.Dppm. However, the fact that the receiving value is usually not same with machine's catalog and there is not research of estimating accuracy of GNSS baseline in Vietnam. So, leading to the estimation and evaluation for construction is not true. The accuracy of the design of the measurement network by satellite technology is not close to reality. The paper presents the method for determining GNSS baseline accuracy according to the time receive signals for construction networks; Has conducted empirical calculations on a specific network in Vietnam to demonstrate the theoretical issues presented in the paper.
