DIN ISO 16290:2016-09 3 IntroductionTechnology Readiness Levels (TRLs) are used to quantify the technology maturity status of an element intended to be used in a mission. Mature technology

10、 corresponds to the highest TRL, namely TRL 9, or flight proven elements.The TRL scale can be useful in many areas including, but not limited to the following examples:a) For early monitoring of basic or specific technology developments serving a given future mission or a family of future missions;b

11、) For providing a status on the technical readiness of a future project, as input to the project implementation decision process;c) In some cases, for monitoring the technology progress throughout development.The TRL descriptions are provided in Clause 3 of this International Standard. The achieveme

12、nts that are requested for enabling the TRL assessment at each level are identified in the summary table in Clause 4. The detailed procedure for the TRL assessment is to be defined by the relevant organization or institute in charge of the activity.This International Standard was produced by taking

13、due consideration of previous available documents on the subject, in particular including those from the National Aeronautics Space Administration (NASA), the US Department of Defence (DoD) and European space institutions (DLR, CNES and ESA).DIN ISO 16290:2016-09 4 Space systems Definition of the Te

They are validated through successful in orbit operation and can be verified through a collection of element verifications on the ground which comprehensively cover the operational case.Note 2 to e

Conversely, reproducibility implicitly introduces the notion of time in the mature technology definition. A technology can be declared mature at a given time, and de

42、nufacture, test and operation of the element and when, in addition, the element meets a set of performance requirements in the actual operational environment.The element under consideration is assumed to be a physical part of a system. Systems are generally subdivided into sub-systems with potential

43、ly several sub-levels. The element can be any part of the system and is not necessarily a specific sub-system or at a specific sub-level.A prerequisite for TRL assessment is the identification of the element that is subject to the assessment. Higher TRLs further require the definition of the perform

44、ance requirements, and therefore require the knowledge of the mission and the system where the element is intended to be used and its operational environment. Performance requirements can be preliminary and targeting several missions at low TRLs, then progressively refined and verified at higher lev

45、els.The entire TRL scale applies for a given element. Therefore, there is no gradation in the element complexity when moving from low to high TRLs.Higher TRLs also imply that the element is in its final form and is being integrated into a system for validation or use. Therefore, the TRL of a given e

46、lement may be downgraded if this same element is used in a different system, unless all environment and interface requirements for the element in the new system can be demonstrated to be equally or less demanding than for the original system.A TRL assessment is valid for a given element and at a giv

47、en point in time. It may evolve if the conditions that prevailed at the time of the assessment are no longer valid. Such a situation may lead to TRL reassessment and degradation, which can occur in particular when the re-build/re-use of an element is envisioned. Examples are when the obsolescence of

48、 the electronics requires modifications or when the production involves a specific knowledge that has been lost.The time or effort to move from one TRL to another are technology dependent and are not linearly connected to the TRL scale. Experience shows that they can vary widely depending on the element and
