Проанализированы известные методы калибровки и оценки характеристик реализованных космических гравитационных градиентометров. Выделены и описаны основные этапы калибровки и оценки характеристик градиентометров: лабораторная оценка поправочных коэффициентов, оценка поправочных коэффициентов при эксплуатации, оценка поправочных коэффициентов по независимым данным, калибровка. Предложены два метода калибровки космических градиентометров: с использованием комплекса наземных полигонов и бортового стенда. Исследованы принципы построения элементов комплекса наземных полигонов, сформирована их структура. Проанализирована возможность применения бортовой массы на борту космического аппарата для калибровки космического градиентометра. Выделены основные параметры бортового стенда.

An analysis is made of the known methods for calibrating and evaluating the parameters of implemented space gradiometers. There are 4 main stages: laboratory assessment of amendments, assessment of amendments during operation, assessment of amendments from independent data, calibration. A description of each step is provided. Two methods for calibrating space gradiometers are proposed: based on a complex of calibration sites and an onboard stand. The principles of building elements of a complex of calibration sites are investigated and their structure is formed. The analysis of the possibility of using the onboard mass on board the spacecraft for calibrating the space gradiometer is carried out. The main parameters of the onboard stand are highlighted. Scope: determination of metrological characteristics of space gravitational gradiometers.
