An engineering model development programme verified optical alignment techniques and crucially, demonstrated structural stability through vibration tests. As a result of this, the flight model camera has been assembled at the Space Science & Technology Department of CCLRC's Rutherford Appleton Laboratory in the UK, in preparation for launch in 2005. The camera has been designed to be compact and lightweight so that it may be flown on a low cost mini-satellite (~120kg launch mass). To achieve this, the camera utilises an off-axis three mirror anastigmatic (TMA) system, which has the advantages of excellent image quality over a wide field of view, combined with a compactness that makes its overall dimensions smaller than its focal length. Keeping the costs to a minimum has been a major design driver in the development of this camera. The camera is part of the TopSat mission, which is a collaboration between four UK organisations; RAL (Rutherford Appleton Laboratory), SSTL (Surrey Satellite Technology Ltd.), QinetiQ and Infoterra. Its objective is to demonstrate provision of rapid response high-resolution imagery to fixed and mobile ground stations using a low cost mini-satellite. This paper describes the opto-mechanical design, assembly and alignment techniques implemented and reports on the test results obtained to date.","PeriodicalId":184892,"journal":{"name":"International Conference on Space Optics — ICSO 2004","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124949567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the framework of earth and scientific observation, high and very high-resolution optical payloads have been developed. This leadership allowed EADS-ASTRIUM to propose a large and complete range of space-based system for optical observation. Ceramic mirrors and structures are becoming attractive for high precision light weighted opto-mechanical applications. Developments over the past 15 years by EADS-ASTRIUM and by Boostec have demonstrated the feasibility and versatility of the SiC material for numerous applications. The most favorable characteristics of this material are high stiffness, high thermal conductivity and low thermal expansion (CTE). Furthermore, SiC allows relatively quick and cheap manufacturing of components because the components can be shaped with conventional tools in a milling process of the green body material. Through different joining processes, SiC allows for large size applications and systems. Only the scale of the available production facilities, the largest of which currently is 4 m in diameter, limits size of the structures and mirrors that can be manufactured . After a short recall of the SiC material properties, this paper describes recent impressive developments namely the ∅ 3,5m primary mirror for Herschel telescope, the ∅ 1,5m primary mirror for Aladin telescope and the 1,5m x 0,6 m mirror demonstrator for the GAIA mission. Main conclusion from the feasibility study of the ∅ 3,5m SPICA telescope are also presented.","PeriodicalId":184892,"journal":{"name":"International Conference on Space Optics — ICSO 2004","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117228022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
