WFI multi-spectral images of the deep universe could also benefit to many other research area in astrophysics. The WFI payload includes a 2 m class telescope, a 1 square degree field of view imaging camera and a low-resolution integral field spectrometer.

The highly accurate deep space navigation, interplanetary laser ranging and communication, interferometry and metrology, high precision frequency standards, precise pointing and attitude control, together with drag-free satellite attitude control will revolutionize the field of experimental gravitational physics. Deep space laser ranging will be ideal for gravitational wave detection, and testing relativity and measuring solar system parameter to an unprecedentend accuracy. We use ASTROD (Astrondynamical Space Test of Relativity using Optical Devices) with three spacecraft and ASTROD I with a single spacecraft as examples for application those technologies. In this paper, we will present the scientific goals and optical requirements of the different mission scenarios, and will summarize the progress of ASTROD / ASTROD I mission studies with emphasis on optical interferometry, the acceleration noises, drag-free attitude control and low-frequency gravitational wave sensitivity.","PeriodicalId":224177,"journal":{"name":"International Conference on Space Optics — ICSO 2006","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121365342","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}
