Reference architecture for space data systems
Architectures for terrestrial data systems that are built and managed by a single organization are inherently complex. In order to understand any large-scale system architecture, and to judge its applicability for its nominal task, a description of the system must be produced that exposes a number of distinct viewpoints. Within the CCSDS Architecture Working Group we have adapted the Reference Model for Open Distributed Processing to describe large, multi-national, space data systems.

Preliminary Link between the Hipparcos 37-Month Fast Solution and a VLBI Extragalactic Reference Frame
Results of the VLBI astrometric program of 12 radio-emitting stars are presented and used to provide a preliminary link of the Hipparcos 37-month FAST solution to a VLBI extragalactic reference frame. The formal precisions of this link are 0.5 milliarcsecond in global rotation and 0.5 milliarcsecond per year in residual rate of rotation.

Total dose performance of radiation hardened voltage regulators and references
Total dose test of commercially available radiation hardened bipolar voltage regulators and references show reduced sensitivity to dose rate and varying sensitivity to bias under pressure. Behavior of critical parameters in different dose rate and bias conditions is compared and the impact to hardness assurance methodology is discussed.
