Determination of Cartesian coordinates of building can be performed using various surveying methods. One of these methods is real-time measurement in RTN GNSS mode. Therefore, tests were carried out that led to surveying contractors being presented with an alternative of using RTN GNSS surveys to determine the location of a building with high reliability and accuracy. This solution involves the harmonisation of various surveying methods hereinafter referred to as the HMM algorithm. After using the HMM algorithm, linear deviations dL were obtained for the determined X, Y coordinates at the level of 0.03 m and the mean location errors of the corners of the building at the level of 0.02 m, which were not significantly different from the reference values. Test tests and their verification allowed to state that the HMM algorithm was very useful for determining the location of a building structure in real time.

可以使用各种测量方法来确定建筑物的笛卡尔坐标。其中一种方法是 RTN GNSS 模式下的实时测量。因此，进行了一些测试，导致勘测承包商获得了使用 RTN GNSS 勘测的替代方案，以确定具有高可靠性和准确性的建筑物的位置。该解决方案涉及各种测量方法的协调，以下称为 HMM 算法。使用HMM算法后，确定的X、Y坐标在0.03 m水平处的线性偏差dL和0.02 m水平处建筑物拐角的平均位置误差与参考值没有显着差异值。
