Understanding International GNC Hardware Trends

An industry-wide survey of guidance, navigation and control (GNC) sensors, namely star trackers, gyros, and sun sensors was undertaken in 2014, in which size, mass, power, and various performance metrics were recorded for each category. A multidimensional analysis was performed, looking at the spectrum of available sensors, with the intent of identifying gaps in the available capability range. Mission types that are not currently well served by the available components were discussed, as well as some missions that would be enabled by filling gaps in the component space. This paper continues that study, with a focus on reaction wheels and magnetometers, as well as with updates to the listings of star trackers, gyros, and sun sensors. Also discussed are a framework for making the database available to the community at large, and the continued maintenance of this database and the analysis of its contents

Overcoming the Limits to Change and Adapting to Future Challenges: Governing the Transformation of Destination Networks in Western Australia

This article presents a study that investigates the organizational transformation of regional tourism in Western Australia in order to make it fit for future. In principle, it explores how the past influences adaptation to upcoming challenges in the Asia-Pacific region (and beyond), such as for example reorganizing territorial dimensions in destination management. Specifically, the article considers how an imposed merger of two previously separate tourism regions affects the established communication and collaboration structures among stakeholders. To analyze the inhibiting force of historically grown destination network structures and the potential for changing these networks, the article combines the concepts of path dependence/path creation and stasis-based/change-based momentum with a quantitative social network analysis. The study provides evidence of remarkable persistence of destination networks. However, the study exhibits also path-creating processes: A transformation of destination networks to meet future challenges in tourism seems to depend largely on an effective governance of informal communication
