The purpose of this paper is to describe the initiative set up at the European Space Operations Centre (ESOC) to investigate how knowledge management principles could offer solutions, while adapting to a world where technology and innovative processes are rapidly changing.

The paper investigates the challenges of implementing a corporate knowledge management system in ESOC, where currently the knowledge is managed in several different ways. The driver of the knowledge management initiative has been the need for developing a system able to locate intellectual capital and technical expertise.

The paper has identified the following main items to be considered in support of the ESOC knowledge management initiative: need for a consistent set of documentation, maintained under configuration control and regularly updated to reflect actual status; formation of cross‐support functional teams; usage of a Centralized ESTRACK Status and Diagnostic System (CESADS) as a supervisory/diagnostic tool for the ground operations; and need for knowledge management evolution.

Although just at the starting‐point, the needs and the benefits of the above points have been acknowledged at ESOC to guarantee reliable and efficient execution of the responsibilities of the Centre. The points raised are expected to be of interest to space industry planners, executives and researchers.

This paper aims to focus on research work related to metamaterial-based sensors for material characterization that have been developed for past ten years. A decade of research on metamaterial for sensing application has led to the advancement of compact and improved sensors.

In this study, relevant research papers on metamaterial sensors for material characterization published in reputed journals during the period 2007-2018 were reviewed, particularly focusing on shape, size and nature of materials characterized. Each sensor with its design and performance parameters have been summarized and discussed here.

As metamaterial structures are excited by electromagnetic wave interaction, sensing application throughout electromagnetic spectrum is possible. Recent advancement in fabrication techniques and improvement in metamaterial structures have led to the development of compact, label free and reversible sensors with high sensitivity.

The paper provides useful information on the development of metamaterial sensors for material characterization.
