This document provides guidelines for specifying the qualitative estimation of the solar wind energy input into the magnetosphere with use of operative ground-based information on the polar cap magnetic activity (PC index). The solar wind energy incoming into the magnetosphere predetermines development of the magnetospheric disturbances: magnetic storms and substorms. Magnetospheric disturbances include a wide range of phenomena and processes directly affecting human activity, such as satellite damage, radiation hazards for astronauts and airline passengers, telecommunication problems, outrages of power and electronic systems, effects in the atmospheric processes, and impact on human health. This document is intended for on-line monitoring the magnetosphere state and nowcasting the intensity and extent of magnetic disturbances as well as parameters of the high-latitude ionosphere. The method and accuracy of estimating is ascertained by close relationship between the PC index and interplanetary electric field (as the most geoeffective solar wind parameter), on the one hand, and between the PC index and magnetoshpheric disturbances, on the other hand.

This document defines the safety programme and the technical safety requirements that are implemented in order to comply with the safety policy as defined in ISO 14300‑2. It is intended to protect flight and ground personnel, the launch vehicle, associated payloads, ground support equipment, the general public, public and private property, and the environment from hazards associated with space systems. Launch site operations are described by ISO 14620‑2 and flight safety systems in ISO 14620‑3. The safety policy is applied by implementing a system safety programme, supported by risk assessment, which can be summarized as follows. a) Hazardous characteristics (system and environmental hazards) and functions with potentially hazardous failure effects are identified and progressively evaluated by iteratively performing systematic safety analyses. b) The potential hazardous consequences associated with the system characteristics and functional failures are subjected to a hazard reduction sequence whereby: hazards are eliminated from the system design and operations; hazards are minimized; and hazard controls are applied and verified. c) The risks that remain after the application of a hazard elimination and reduction process are progressively assessed and subjected to risk assessment, in order to: show compliance with safety targets; support design trades; identify and rank risk contributors; support apportionment of project resources for risk reduction; assess risk reduction progress; and support the safety and project decision-making process (e.g. waiver approval, residual risk acceptance). d) The adequacy of the hazard and risk control measures applied are formally verified in order to support safety validation and risk acceptance. e) Safety compliance is assessed by the project and safety approval obtained from the relevant authorities.

This document describes minimum requirements for small spacecraft. Small spacecraft may employ untraditional spacecraft development and management philosophy. These spacecraft projects are usually budget-limited or mass-limited, which makes a single (exclusive) launch unaffordable. The scope of this document encompasses different categories of small spacecraft — so-called mini-, micro-, nano-, pico- and femto-, as well as CubeSat, spacecraft. Therefore, for the sake of convenience, the term "small spacecraft" is used throughout this document as a generic term. Regardless of the development philosophy, there are minimum requirements every spacecraft complies with. This document explicitly states those requirements and also refers to existing applicable standards. In that sense, this document serves as the top document to cover the minimum requirements for various stages of small spacecraft system life-cycle — with emphasis on design, launch, deployment, operation, and disposal phases. In this way, (1) safety, (2) harmlessness to co-passengers and launcher, and (3) debris mitigation, are all assured. This document is addressed to small spacecraft developers, as well as dispenser providers and/or the launch operators.

ISO 19924:2017 specifies a framework to meet test and process requirements and acts as a supplement to ISO 15864. The acoustic test system, the technical requirements and the procedures for acoustic tests in reverberant chambers are described. Furthermore, the criteria for the manual test interruption and evaluation are also described. The technical requirements in ISO 19924:2017 can be tailored to fulfil the objectives of tests.

ISO 19683:2017 provides test methods and test requirements for design qualification and/or acceptance of small spacecraft or units. It provides the minimum test requirements and test methods to qualify the design and manufacturing methods of commercial small spacecraft and their units and to accept the final products. ISO 19683:2017 places emphasis on achieving reliability against infant mortality after satellite launch to orbit while maintaining low cost and fast delivery. ISO 19683:2017 is applied to satellites whose development methods are different from the ones used for traditional satellites that have little room for risk tolerance, as shown in Figure 1. The scope of this document encompasses different categories of small spacecraft, so-called mini-, micro, nano-, pico- and femto-, as well as CubeSat, spacecraft. Therefore, for the sake of convenience, the term "small spacecraft" is used throughout this document as a generic term. ISO 19683:2017 includes CubeSat, as long as it is developed with the untraditional processes.
