AbstractThe Consultative Committee for Space Data Systems (CCSDS) is an international organization of national space agencies that is branching out to provide new standards to enhanced reuse of spacecraft equipment and software. These Spacecraft Onboard Interface (SOIF) standards will be directed towards a spacecraft architecture, as a distributed system of processors and busses. This paper will review the services that are being proposed for SOIF. These services include a Command and Data Acquisition Service, a Time Distribution Service, a Message Transfer Service, a File Transfer Service, and a CCSDS Packet Service. An Instrument & Subsystem “Plug & Play Service is currently under study, but is included in this paper for completeness.

CCSDS SPACE LINK EXTENSION SERVICE MANAGEMENT STANDARDS AND PROTOTYPING ACTIVITIESPietras, John; Global Science & Technology, Inc. (International Foundation for Telemetering, 2003-10)The Consultative Committee for Space Data Systems (CCSDS) is developing standards for the interface through which spaceflight mission managers request tracking, telemetry, and command (TT&C) and Space Link Extension (SLE) services from TT&C ground stations and networks. The standards are intended for use not just by the spaceflight projects and networks operated by the CCSDS member agencies, but also by commercial networks and networks operated by other governmental agencies. As part of the process of developing the standards, several prototypes are under development. This paper presents a summary status of both the emerging service request standards and the prototypes that implement them.
VIRTUAL REFERENCE SERVICES: IMPLEMENTATION OF PROFESSIONAL AND ETHICAL STANDARDSShachaf, Pnina (2007-12)Virtual reference, which allows users to connect easily with librarians online, is becoming popular. Librarians answer thousands of questions every day over the Internet. As the service matures, professional associations publish standards that provide professional guidelines to improve the quality of the services. This article focuses attention on the quality of these e-services in light of professional and ethical standards in the field. It examines the extent to which librarians adhere to professional and ethical guidelines and the role that virtual reference plays in providing services to diverse user groups. First, it discusses adherence to the professional standards and shows that the professional behaviors of librarians vary depending on user, institution, and request types. Then, it discusses the extent to which librarians provide equitable online reference services to diverse users groups and the inconsistent findings from empirical research.
