Abstract
We study potential possibilities of space constellation consisting of two pairs of spacecraft moving in different orbits, the so-called next generation gravity missions, aimed at increasing the spatial and temporal resolution of measurements and improving the accuracy of the recovery of the Earth’s gravity field. As a result of numerical simulation of the orbital motion of the multiple spacecraft constellation and solving the inverse problem of recovering the Earth’s gravitational field based on model measurements performed in this constellation, a multiple configuration with orbital parameters \(h = 370\) km, \(i = 90.5^\circ \) and \(h = 370\) km, \(i = 70.0^\circ \), was found. Such a multiple constellation makes possible to increase both the spatial and temporal resolution of the Earth’s gravity field models with a significant refinement of zonal, sectorial and tesseral harmonics compared to the one-pair near-polar configuration.
