The CCSDS File Delivery Protocol (CFDP?reference [1]) has been designed to support the transfer of files in a variety of mission scenarios. CFDP offers different qualities of service ranging from best effort to fully reliable and has been specifically optimized for long delay, noisy, and disjoint links. CFDP requires a simple minimum service from the underlying protocols, operating over any link…

ISO 20107:2015 is one of a family of documents specifying the Spacecraft Onboard Interface Services (SOIS)-compliant service to be provided in support of applications. ISO 20107:2015 defines the SOIS Device Virtualisation Service (DVS). The definition encompasses specification of the service interface exposed to onboard software (user applications and libraries) as well as the conceptual mapping…

ISO 18423:2015 defines both transparent and regenerative PN ranging systems for non?data relay satellite users. The specification for PN code components and generation, on-board spacecraft regenerative/transparent processing, ground station processing, and uplink and downlink signal modulation are defined in this document. This Recommended Standard does not specify a) individual implementations…

ISO 22663:2015 defines the Data Link Layer (Framing, Medium Access Control, Data Services, and Input/Output [I/O] Sublayers). The specifications for the protocol data units, framing, media access control, expedited and sequenced-controlled data transfer, timing service, I/O control, and the procedures for establishing and terminating a session between a caller and responder are defined in this…

ISO 21460:2015 defines the Proximity-1 Space Link Protocol Physical Layer. The specification for the channel connection process, provision for frequency bands and assignments, hailing channel, polarization, modulation, data rates, and performance requirements are defined in this document. Currently, the Physical Layer only defines operations at UHF frequencies for the Mars environment. The Data…

ISO 21459:2015 defines synchronization and channel coding schemes for Proximity-1 links in terms of: a) the services provided to the users of this specification; b) data formats; and c) the procedures performed to generate and process the data formats. It does not specify: a) individual implementations or products; b) the methods or technologies required to perform the…

L'ISO 20685-2:2015 concerne les protocoles d'essai des systèmes d'exploration à l'aide de scanners 3D de surface permettant de collecter des données sur la forme du corps humain et les mesurages. Elle ne s'applique pas aux instruments qui mesurent le déplacement de repères individuels. La majeure partie de l'ISO 20685-2:2015 concerne les scanners pour le corps entier…

ISO 20685-2:2015 addresses protocols for testing of 3-D surface-scanning systems in the acquisition of human body shape data and measurements. It does not apply to instruments that measure the motion of individual landmarks. While mainly concerned with whole-body scanners, it is also applicable to body-segment scanners (head scanners, hand scanners, foot scanners). This International Standard…

Le présent document s’adresse aux producteurs d’oeufs de consommation. Il ne vise pas les producteurs qui font l’élevage de reproducteurs ou de pondeuses ou qui ont des reproducteurs pour la ponte. Le présent document a été élaboré en vue de servir de document de référence dans le cadre d’activités d’évaluation de la conformité des processus visés. NOTE — L’évaluation de la conformité est…
