BS ISO 18438 is one of a family of documents specifying the SOlS-compliant services to be provided by onboard subnetworks.
This International Standard defines services and service interfaces provided by the SOIS Subnetwork Test Service. Its scope is to specify the service only and not to specify methods of providing the service over a variety of onboard data links.
This International Standard conforms to the principles set out in the Spacecraft Onboard Interface Services Green Book and is intended to be applied together with it. The protocols which provide this service are to be documented for individual links, and this may be in the purview of individual missions, agencies, or CCSDS, depending on future circumstance.
The scope and field of application are furthermore detailed in subclause 1.2 of the enclosed CCSDS publication.
Requirements are the technical recommendations made in the following publication (reproduced on the following pages), which is adopted as an International Standard:
CCSDS 855.0-M-1, December 2009, Spacecraft Onboard Interface Services一Subnetwork Test Service.
For the purposes of international standardization, the modifications outlined below shall apply to the specific clauses and paragraphs of publication CCSDS 855.0-M-1.
This part is information which is relevant to the CCSDS publication only.
CCSDS Recommendations take two forms: Recommended Standards that are prescriptive and are the formal vehicles by which CCSDS Agencies create the standards that specify how elements of their space mission support infrastructure shall operate and interoperate with others; and Recommended Practices that are more descriptive in nature and are intended to provide general guidance about how to approach a particular problem associated with space mission support. This Recommended Practice is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommended Practice is entirely voluntary and does not imply a commitment by any Agency or organization to implement its recommendations in a prescriptive sense.BS ISO 18438 pdf download.
