В статье рассматриваются подходы к формированию критериальной базы оценки эффективности при проектировании перспективных космических систем на примере космических систем мониторинга гравитационного поля Земли. Сформулированы основные требования к созданию критериальной базы. Дано определение критерия и обобщенного критерия эффективности применительно к элементам перспективных космических систем. Рассмотрены общие и частные критерии эффективности перспективных космических систем в зависимости от назначения конкретной системы (оборонного применения, гражданские, многоцелевые). The article considers approaches to the formation of a criteria base for evaluating the effectiveness of the design of advanced space systems on the example of space systems for monitoring the Earth's gravitational field. The main requirements for creating a criteria base are formulated. The definition of the criterion and the generalized criterion of efficiency in relation to the elements of advanced space systems is given. General and specific criteria for the effectiveness of advanced space systems are considered, depending on the purpose of a particular system (defense, civil, multi-purpose).

The article considers approaches to the formation of a criteria base to evaluate the effectiveness of the design of advanced space systems on the example of space systems for monitoring the Earth’s gravitational field. The main requirements for creating a criteria base are formulated. The definition of the criterion and generalized criterion of efficiency in relation to the elements of advanced space systems is given. General and specific criteria for the effectiveness of advanced space systems are considered depending on the purpose of a particular system (defense, civil, and multi-purpose).

The structure of theories used in determining the gravitational field from the perturbations of orbits of artificial satellites is discussed and it is shown how it corresponds to the fact that small departures from a Keplerian ellipse are readily observed. Some current problems are mentioned. Statistical problems in the estimation of parameters of the field from orbital data are considered and recent estimates are summarized

The Chairman, W. Fricke, President of Commission 4, opened the Joint Discussion by drawing attention to the purpose and proposed procedure for the meeting. The Joint Discussion had been arranged by the Executive Committee of the Union in order to avoid the necessity for separate discussions by each Commission that was affected by the Report of the Working Group on the IAU System of Astronomical Constants. The Organizing Committee therefore proposed the following resolution:‘The members of the IAU at this Joint Discussion recommend to the Executive Committee that the following resolution be put before the General Assembly: “The International Astronomical Union endorses the final list of constants prepared by the Working Group on the System of Astronomical Constants and recommends that it be used in the national and international astronomical ephemerides at the earliest practicable date.’”
