- Аннотация: Satellite constellations consisting of two spacecraft (SC) pairs moving in different orbits—the socallednext-generation gravity missions—are analyzed for establishing their optimal orbital parameters providinghigh spatial and temporal resolution of the Earth’s gravity. Based on the numerical modeling, the SCorbital elements simultaneously satisfying the requirements of smallest changes in intersatellite ranges andlargest coverage of the Earth’s surface by the SC sub-satellite tracks are determined. The optimal orbitalparameters of multi-pair constellation provide 97% coverage of the Earth’s surface by sub-satellite paths over a 10-day interval with angular resolution of 1° × 1° corresponding to degree n ≈ 200 geopotential decomposition, which is four times as high in terms of spatial resolution and three times as high in terms of temporalresolution as in case of using a single GRACE type constellation.
