Cooling requirements are minimized due to the single monolithic prism-like grating design. The configuration has the potential to be the optimal sciencegrade imaging spectroscopy solution for lighter-than-air (LTA) vehicles and unmanned aerial vehicles (UAV) due to its small form factor and relatively low power requirements. The QWIP allows for optimum spatial and spectral uniformity and provides adequate responsivity to allow for near 100mK noise equivalent temperature difference (NEDT) operation across the EOTIR passband. These tests are in preparation for the deployment of the Hypserspectral Thermal Infrared Spectrometer (HyTES) which is currently being funded under NASA's instrument incubator program (IIP). Test results show NEDT, linearity as well as applicable earth science emissivity target results (silicates, water) measured in direct sunlight. A calibration is also performed to derive direct water temperature using a well calibrated transfer radiometer operating simultaneously.","PeriodicalId":378029,"journal":{"name":"2010 IEEE Aerospace Conference","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129868630","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}

TU Munich's Institute of Astronautics (LRT) considers the degree of flexibility required of an OOS system to be only achievable by keeping human operators in the loop, by means of telepresence. However, the absence of important sensory input, such as acoustic and tactile information and peripheral vision, the lack of reference points for discerning orientations, distances and velocities, and the unfamiliar behavior and motion of objects in space reduce the situational awareness of the human operator. In order to provide the human operator with additional visual input and to enable him/her to take up vantage points which would not be available by means of platform-fixed or manipulator-fixed sensors, the utility of a dedicated robotic camera arm is investigated which will be used by the human operator for judging relative attitude and position of chaser and target vehicle and for viewing the remote work site from otherwise unattainable angles and over obstacles. The stereo video stream delivered by this so-called “Third Eye” will be superimposed with head-up display type graphics in order to provide the operator with attitude and position cues. These enable him/her to integrate the additional visual information into his mental model of the surroundings. Operator performance and maneuver safety is also supported by the projection of laser grids onto the surfaces of the target satellite, thereby facilitating attitude and position determination during station keeping.1 2","PeriodicalId":378029,"journal":{"name":"2010 IEEE Aerospace Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129675119","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}

Two objectives of this program are developing a general electronic student that makes use of machine learning algorithms to learn from the kind of focused instruction typically provided by a human teacher and creating a repository of automated curricula that can be taught to the student. This paper focuses on the second objective, describing a curriculum developed for the BL program to both instruct and test the student that places the electronic student (eStudent) in the role of an International Space Station (ISS) flight controller. The eStudent is taught how to detect and diagnose single-fault problems within the thermal control system of the ISS. During each lesson, the eStudent interacts with an ISS simulator to review alerts and access telemetry values. To obtain greater visibility into its diagnostic reasoning, the eStudent is trained to create an external representation of its reasoning about the current problem - a diagnostic rationale. This includes describing potential problems, hypothesizing possible events and states, positing possible causal explanations as rationale assertions, seeking evidence for or against these assertions, projecting possible risks, and using possible risks to focus attention when developing a rationale. In addition to describing the curriculum developed as part of the first year of the BL program, we also describe some of the future directions we will investigate as part of the second year. 1,2","PeriodicalId":378029,"journal":{"name":"2010 IEEE Aerospace Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129010194","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}

That method is applicable for complex geometry enclosure. The computational domain is divided into many tetrahedral volume cells, which is easily applied into structured or unstructured. A general discretization equation based on step scheme for spatial differencing and azimuthal discretization in angular domain was derived. In order to validated the developed unstructured finite volume method, three test cases were chosen, including a cubic enclosure with absorbing-emitting medium, an equilateral triangular enclosure with absorbing-emitting medium, a 3D L-shaped enclosure with absorbing-emitting/scattering medium. All the solutions based on the present method have a good agreement with available other solutions. Then, one case with more complex geometry, a hollow cubic enclosure with absorbing-emitting and isotropic scattering medium, was investigated. The effects of scattering albedo on wall radiative flux, incident radiation and radiative flux divergence were analyzed. It was found that the developed model is reliable and accurate and suitable for radiative transfer in complex 3-D enclosure with inhomegeneous absorbing-emitting and scattering medium.12","PeriodicalId":378029,"journal":{"name":"2010 IEEE Aerospace Conference","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126966244","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}
