Last Tuesday councilmen Mike Klein and Fred Valtin stepped down after completing two terms (eight years) on the council. Both had served as mayor - Valtin three times in 1984,1985 and 1987. Klein, just finishing up his second stint as His Honor, served the first time in 1983. Valtin, who is still convalescing from a heart attack sufferd last June, said he was deeply touched by the honor but he was "confident the city is in good hands."

In the aerospace sector Wales has around 10% of the overall UK workforce and arguably punches above its weight. When it comes to the space sector Wales has only around 1% of the overall UK personnel and so there is a huge opportunity for growth in a sector which is growing significantly. The UK space sector has set a target of achieving a 10% share of the predicted £400 billion per annum global space market in 2030. A 5% share of this for Wales would equate to £2 billion per year and this is a realisable target which we aim to achieve and will work to exceed. Currently there are around 5000 satellites circling the earth in various orbits. Only 2,000 of these are operational. If OneWeb, Starlink and other potential networks continue with their projected growth that number could increase by a massive 4,500% in the next five years! Demand for data is on the increase, and launching satellites that offer broadband internet service will help to drive down the cost of that data. Reusable rockets and satellites will also help drive down costs and so too will the mass-production of satellites and the development of satellite technology.

  • Basic Plan for Space Policy
    BasicBasic PlanPlan forfor SpaceSpace PolicyPolicy ～Wisdom of Japan Moves Space～ Secretariat of Strategic Headquarters for Space Policy June, 2009 1‐11‐28 Akasaka, Minato‐Ku, Tokyo, 107‐0052 TEL 03‐5114‐1935 ／ FAX 03‐3505‐5971 HP http://www.kantei.go.jp/jp/singi/utyuu/index.html What is the Basic Plan In view of the situation in which the role of the use and R&D of space has been expanding globally, the Basic Space Law was enacted in May 2008 to cope with challenges to Japan’s space policy such as lack of a comprehensive strategy as a whole nation due to the absence of a policy headquarter. The Basic Plan was decided as the first national comprehensive strategy by the Strategic Earthrise Headquarters for Space Policy, which was established based on the Basic Space Law and chaired by the Prime Minister. This Plan is a five‐year‐program, from FY2009 to FY2013, foreseeing the next ten years, (Apr.5, 2008) describing the basic policy and the measures which the Government should take during this period. A Special Committee for Space Policy, whose members are opinion leaders from various fields, chaired by Mr. Jitsuro Terashima, Chairman of Japan Research Institute, was established to make recommendations on the plan. Additionally we have received about 1500 public comments on this matter. The Government will act comprehensively and systematically regarding this Basic Plan.

  • Business Partnership and Technology Transfer Opportunities in the Space
    EU-Japan Centre for Industrial Cooperation 日欧産業協力センター The Space Sector EU- Japan business and technological cooperation potential Veronica La Regina Minerva Fellow Tokyo 2015 1 Abstract This report aims to propose the best way of pursuing the EU-Japan industrial cooperation in the field of Space. Firstly, it reviews European and Japanese current cooperation in the field of Space. Secondly, it investigates the current level of trade between the two partners in order to understand the best way to generate further cooperation. Thirdly, the Report hopes to inform both sides about each region’s current Space sector landscape from the political, policy and industrial point of views. Fourthly, it identifies areas of industrial cooperation for which local gaps in knowledge or experience could be filled by foreign expertise, for example the European technological gaps in the small-size satellite constellation could be filled by the Japanese expertise while the Japanese intention to become more commercially oriented could be supported by the more expansive European experience in this area. Finally, recommendations to the Japanese and European stakeholders are provided.

  • Application of Matched Statistical Filters for Earthcare Cloud Doppler Products Ousmane O
    IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING, VOL. 52, NO. 11, NOVEMBER 2014 7297 Application of Matched Statistical Filters for EarthCARE Cloud Doppler Products Ousmane O. Sy, Simone Tanelli, Pavlos Kollias, and Yuichi Ohno Abstract—This paper presents a method for filtering the ran- TABLE I dom noise that affects spaceborne Doppler measurements of at- CHARACTERISTICS OF THE EARTHCARE CPR [21] mospheric velocities. The proposed method hinges on adaptive low-pass filters that apply to the measured pulse-pair correlation function. The parameters of the filters are found by optimizing the statistics of the velocity residue of the filter. The method is illustrated by simulations of the cloud-profiling radar of the fu- ture Earth Cloud, Aerosol and Radiation Explorer (EarthCARE) mission of the European Space Agency and the Japanese Space Exploration Agency. These simulations, which do not include strong convection, show the higher performance of the filters when compared with the traditional increase of the along-track integration length. The results obtained with the filters show that velocity accuracies of 0.48, 0.42, and 0.39 m · s−1 are achievable at PRF = {6.1, 7, 7.5} kHz, respectively, while preserving the initial 500-m sampling of the measured EarthCARE data. These results also show the potential benefits of avoiding excessive along- track integration, for postprocessing tasks such as dealiasing or Given the configuration of EarthCARE, which is detailed the retrieval of the vertical distribution of the atmospheric velocity in Table I, the CPR will have to overcome various challenges (e.g., longer than 5 km for cases consistent with the climatologies to accurately measure Doppler velocities using a pulse-pair represented in this data set).
