A 50% splitter was used to combine light beams from two separate FOVs, while only a single objective lens and optical detector are used. In this way, double FOV configuration allows increased accuracy in attitude determination by taking advantage of the ability to examine two orthogonal FOVs simultaneously. There is a demand for optical tag due to each frame contained overlapping star images coming from separate FOVs. In this paper we propose a method for identifying two FOVs by tagging the images with different shaped diffraction patterns. We insert a circular diaphragm in the optical channel 1# and non-circular (elliptical or rectangular) in the channel 2#, so that images with distinctive features are produced at CCD photosensitive surface - circular Airy disc for the FOV-1# and elliptical contour (with side lobe or distortion) for FOV-2#. The effects of elliptical sampling window and the signal-to-noise ratio on the accuracy of the centroid estimate for star spots with a Gaussian intensity distribution were discussed theoretically. The optical tagging has one limitation. There is possibility for a star image tagged by non-circular contour, which is confused with smearing trail due to high angular velocity operation (e.g. greater than 1°/s).","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131737132","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}

The design of servicing operations and devices is nowadays one of the most important research field in space robotics. Servicing operations range from regular inspection to the upgrade of components and re-fuelling. It is immediate to notice that, regardless of the operation to be carried out, the success is strictly linked to the way in which the chaser and the target satellites move and interact with respect to each other. The importance of relative motion for rendezvous and docking operations, calls for an approriate laboratory facility able to reproduce orbital conditions. This can be achieved only with a robotic structure that simulates the target and chaser's kinematics and dynamics. In this paper, a complete approach to the problem is presented, from the kinematic analysis to the modelling of the impact. In particular, a spring-dashpot model was chosen for the contact simulation, and a virtual-force control system has been adopted. Then, by considering the system's stability, we extracted the analytical expressions that link the performances of the facility with the range of orbital systems that can be simulated. Furthermore, with the aid of a SimMechanics® numerical model, we inspected the performances of three different control strategies for the movimentation of the robot.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126515279","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}

Up to now haptic technology has never been used in avionics mainly because of two difficulties (notwithstanding other ones): 1) necessity of large mechanical space (because of moving parts); 2) impossibility of detecting a small movement (haptic sensation) in an environment characterized by heavy vibration regime under all frequencies. This proposal overcomes the difficulties by using a haptic touchscreen that has no moving parts (new generation) along with an accurate innovative study of the feedback sensation, physical profile, that allows a univocally defined sense of actuation within any environment; the results presented will show that this system can be implemented with success in particular in the extremely demanding avionic environment. The proposed system is currently the first one in the world that has been developed and tested for avionic environment and this is possible because this technology allows the invention of algorithms that allow the actuating sensation, and effect, whatever the surrounding environment.","PeriodicalId":162403,"journal":{"name":"2014 IEEE Metrology for Aerospace (MetroAeroSpace)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129922093","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}
