Simulation of the Goce Gravity Field Mission,f the spacecraft or thrusters for attitude and drag-free control. Each instrument shows its own error behavior which affects the measurements and the final products in a specific way. Here, the corresponding error Power Spectral Densities (PSD), due to several error sources, are shown..Error PSD’s r追逐 发表于 2025-3-27 13:06:07

Distance Measurement with Electromagnetic Wave Dispersion,aves are different and reach a given elevation at different points and times. If . is independent of the position, the paths of the waves coincide although the waves have different velocities. The length of a path and the travel time of electromagnetic waves in the atmosphere of a flat Earth model aNICE 发表于 2025-3-27 19:01:46
A Global Topographic-Isostatic Model Based on a Loading Theory,from the 1066. earth model, we calculate and discuss the vertical displacements and equipotential surface changes for depths: earth’s surface, . = 36 km and the core-mantle boundary. Numerical results show that the displacements at depth 36 km and the earth surface have the same distribution pattern温和女人 发表于 2025-3-28 01:23:16

Approximation of Harmonic Covariance Functions on the Sphere by non Harmonic Locally Supported Ones2 elements. If finite covariance functions are used and if the observations are ordered in a reasonable manner, the matrices would contain non-zero elements of the order ... This fact made us propose three techniques to approximate harmonic covariance functions by finite supported positive definite袖章 发表于 2025-3-28 09:16:32
