Utilizing the adopted average topographic density of 2670 kg/m3 in the reduction of gravity anomalies introduces errors attributed to topographic density variations, which consequently affect geoid modeling accuracy. Furthermore, the mean gravity alo

The most common approaches for assigning weights to observations in minimum L1-norm (ML1) is to introduce weights of p or p\sqrt{p}, p being the weights vector of observations given by the inverse of variances. Hence, they do not take covariances int

The paper deals with some problems when applying a correction to reduce the effect of vertical refraction in precise leveling observation. An example for calculating the refraction correction for one first order leveling line with length of 109 km in

Examination of possibilities in using geodetic (survey) instruments of the same specifications, but different technical performances is always an interesting geodetic topic. The main purpose of this research is to analyze the accuracy of special purp

We compared the method of least squares (LS), Pope’s iterative data snooping (IDS) and Huber’s M-estimator (HU) in realistic leveling networks, for which the heights or the vertical displacements of points are known. The study was conducted using
