The device provides high-precision ranging and high-speed communication between two spacecraft during rendezvous and docking, whose information is used for estimating their relative position and attitude. This paper proposes two estimation algorithms using UWB properties. The first one estimates the relative position by using the ranging data of the UWB devices and the relative attitude information, which is shared by the UWB communication and provided by the attitude sensors. In the second algorithm, assuming that the attitude sensor of the chaser cannot be used, the relative attitude is estimated using the multiple ranging data of the UWB devices. This research evaluates the estimation accuracy of the two proposed algorithms using a rendezvous simulator, which reveals the conditions to obtain accurate and stable relative position and attitude estimations. This paper will contribute to autonomous navigation method for the proximity rendezvous and docking phases of micro- and nano-spacecraft, which have strict limitations of size and power for navigation sensors.","PeriodicalId":120185,"journal":{"name":"TRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, AEROSPACE TECHNOLOGY JAPAN","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129930191","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}

Using a reflector antenna with a very large aperture on the satellite is a promising option for next-generation mobile communication satellites for small user terminals with small beams. A deployable reflector is a flexible structure instead of the hard dish reflector. To improve the electric al performance of the antenna and avoid performance deterioration caused by aberration, the parabolic reflector must be accurately shaped. We propose continuous beam stabilization by optimizing the parameters for the phased array. If the reflector shape can be measured precisely while in orbit, the beam pattern and antenna performance can be corrected continuously by updating the excitation parameters based on the measured reflector shape with a brief time delay. For the proposed algorithm to perform antenna-pattern stabilization effectively, the shape of the reflector surface should properly determine the optimized phased array parameters to compensate for the deterioration of the antenna pattern. The objective of this study is to confirm the feasibility of the approach to beam pattern correction. The simulations of deformed reflector surfaces deteriorating the antenna pattern reveal that the application of optimized phased array parameters for the reflector shape can compensate for the deformation and recover the antenna pattern.","PeriodicalId":120185,"journal":{"name":"TRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, AEROSPACE TECHNOLOGY JAPAN","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126113056","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}
