On the Advantage of Normal Heightseasily demonstrated by a simple hypothetical example of the spherical non-rotating Earth where the change of marks along the floor of a strictly horizontal tunnel in the spherical mountain massif serves as criterion for the convenience of the system. In this example, the difference in orthometric heConsequence 发表于 2025-3-27 06:32:55

On Combining the Directional Solutions of the Gravitational Curvature Boundary-Value Problem adjustment model. Since the third-order gradients of the gravitational potential are not yet observed by satellite sensors, we synthesise them at the satellite altitude of 250 km from a global gravitational model up to the degree 360 while adding a Gaussian noise with the standard deviation of 6.3责问 发表于 2025-3-27 16:59:55

Impacts of the LARES and LARES-2 Satellite Missions on the SLR Terrestrial Reference Framedeliver TRFs that meet the quality of the LAGEOS based TRF. However, once the LARES are combined with the LAGEOS satellites the formal errors of the estimated ground station coordinates and velocities and the co-estimated Earth Rotation Parameters are considerably reduced. The improvement is beyond疏忽 发表于 2025-3-28 01:11:33

Converted Total Least Squares Method and Gauss-Helmert Model with Applications to Coordinate Transfo bottleneck restricting the application of TLS solutions. CTLS method, together with all the three TLS models reviewed here has been successfully integrated in our coordinate transformation programs and verified with the real case study of 6-parameters Affine coordinate transformation.
