Space environment (natural and artificial) — Cosmic ray and solar energetic particle penetration inward the magnetosphere — Method of determination of the effective vertical cut-off rigidity

This document describes the effective vertical cut-off rigidities of charged particles for near-Earth space and establishes principal requirements for their calculation based on different models of Earth’s geomagnetic field.[1] The techniques are useful for determination of penetrating into the Earth's magnetosphere by charged particle fluxes, as well as for test and estimations of the impact on spacecrafts and other equipment in the near-Earth space.

Space systems — Structural design — Stress analysis requirements

This document provides requirements for the determination of maximum stress and corresponding margin of safety under loading and defines criteria for static strength failure modes, such as rupture, collapse and detrimental yielding. This document does not cover critical-conditions-induced fatigue, creep and crack growths. Notwithstanding these limitations in scope, the results of stress calculations based on the requirements of this document are applicable to other critical condition analysis. This document is applicable to the determination of the stress/strain distribution and margins of safety in launch vehicles and spacecraft load-bearing elements design. Liquid propellant engine structures, solid propellant engine nozzles and the solid propellant itself are not covered, but liquid propellant tanks, pressure vessels and solid propellant cases are within the scope of this document. In accordance with the requirements of this document, the models, methods and procedures for stress calculation can also be applicable to the displacements and deformation calculation, as well as the calculation of loads, applied to substructures and structural elements under consideration. When this document is applied, it is assumed that temperature distribution has been determined and is used as input data.

Space data and information transfer systems — Orbit data messages

This document specifies four standard message formats for use in transferring spacecraft orbit information between space agencies and commercial or governmental spacecraft operators: The Orbit Parameter Message (OPM), the Orbit Mean-Elements Message (OMM), the Orbit Ephemeris Message (OEM), and the Orbit Comprehensive Message (OCM). Such exchanges are used for: a) pre-flight planning for tracking or navigation support; b) scheduling tracking support; c) carrying out tracking operations (sometimes called metric predicts); d) performing orbit comparisons; e) carrying out navigation operations such as orbit propagation and orbit reconstruction; f) assessing mutual physical and electromagnetic interference among satellites orbiting the same celestial body (primarily Earth, Moon, and Mars at present); g) performing orbit conjunction (collision avoidance) studies; and h) developing and executing collaborative maneuvers to mitigate interference or enhance mutual operations. This document includes sets of requirements and criteria that the message formats have been designed to meet. For exchanges in which these requirements do not capture the needs of the participating agencies and satellite operators, another mechanism may be selected. This document is an international standard published under the auspices of CCSDS and International Standards Organization (ISO) Technical Committee 20, Subcommittee 13, developed jointly and in concert with the ISO TC20/SC14. As such, this CCSDS standard is also properly labeled as ISO 26900. The recommended Orbit Data Message format is ASCII (reference REF R_ISO_IEC_8859_1_1998 \h [4] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000001600000052005F00490053004F005F004900450043005F0038003800350039005F0031005F0031003900390038000000 ). This document describes both ‘Keyword = Value Notation’ (KVN) as well as Extensible Markup Language (XML) (reference REF R_505x0b3XMLSpecificationforNavigationDa \h[5] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000002800000052005F00350030003500780030006200330058004D004C00530070006500630069006600690063006100740069006F006E0066006F0072004E0061007600690067006100740069006F006E0044000000 ) formatted messages. Selection of KVN or XML format should be mutually agreed between message exchange partners. NOTE – As currently specified, an OPM, OMM, or OEM file is to represent orbit data for a single spacecraft, and the OCM is to represent orbit data for either a single spacecraft or single parent spacecraft of a parent/child spacecraft deployment scenario. It is possible that the architecture may support multiple spacecraft per file; this could be considered in the future.

Space systems — Lessons learned — Principles and guidelines

This document specifies lessons learned principles and guidelines that are applicable in all space project activities (management, technical, quality, cost and schedule). The application of this document is intended to be included in the supplier quality management system, but can be tailored in individual contracts as agreed by the customer and supplier, depending on: — the content of each project (size, technological level and novelty, particular organization, participants, etc.); — the interest and usefulness of the related information. The lessons learned information can result from any situation which can be encountered in similar contexts for future projects, i.e.: — undesirable experiences to be avoided; — strategies, rules, principles of design, validation, tests and operations proved to be successful or necessary. This document neither endorses nor recommends the transmission of company proprietary information to external entities as part of a lessons learned process. Implementing a formal lessons learned process as outlined in this document makes it possible to capture and benefit from this information. The lessons learned activity is an important contribution to the processing of the preventive and corrective actions specified in ISO 9001, ISO 17666, ISO 14620-1 and ISO 23460. This document also provides lessons learned processes and suggested lessons learned forms.
