Civil and military applications of UAS demand ever-decreasing levels of human involvement and oversight, hence, UAS need to grow in autonomy. Autonomous deconfliction is a capability that is not only essential for the UAS's self-preservation, but also for avoiding damage to static infrastructure and/or to friendly and civilian aircraft flying contiguously. It is also key to the successful completion of the missions assigned to the UAS. Numerous solutions to partial aspects of autonomous deconfliction have been proposed. However, there is an enormous gap in systematic approaches that may be used for Testing and Evaluation (T&E) of autonomous capabilities such as deconfliction. This paper focuses on application of Systems Engineering-oriented tools to the analysis of autonomous deconfliction capability in UAS. The Systems Capability Technical Reference Model (SC-TRM) presented in this work helps in identifying the different aspects of a deconfliction solution. Besides presenting the Systems Engineering-oriented tools and the analysis of the deconfliction problem based on those tools, this paper also proposes venues that may enable concrete implementation and development of T&E methods that are applicable to civil as well as military applications.","PeriodicalId":117250,"journal":{"name":"2009 IEEE Aerospace conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115921465","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}

This Digital Elevation Model was used to compute average solar illumination and Earth visibility with 100 km of the lunar south pole. The elevation data were converted into local terrain horizon masks, then converted into lunar-centric latitude and longitude coordinates. The horizon masks were compared to latitude, longitude regions bounding the maximum Sun and Earth motions relative to the moon. Estimates of Earth visibility were computed by integrating the area of the region bounding the Earth's motion that was below the horizon mask. Solar illumination and other metrics were computed similarly. Proposed lunar south pole base sites were examined in detail, with the best site showing yearly solar power availability of 92% and Direct-To-Earth (DTE) communication availability of about 50%. Similar analysis of the lunar south pole used an older GSSR Digital Elevation Model with 600-meter horizontal resolution. The paper also explores using a heliostat to reduce the photovoltaic power system mass and complexity.","PeriodicalId":117250,"journal":{"name":"2009 IEEE Aerospace conference","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132929108","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}

These are referred to in the literature as “Non-uniform Fast Fourier Transforms” or “NUFFT”. These allow Fourier (trigonometric) interpolation to be done, for a given set of complex DFT coefficients, to a high degree of uniform approximation, in order O(N2) flops. This facilitates the theoretically pleasing prospect of using a Discrete Fourier Series to interpolate image data from a regularly sampled grid to intermediate irregular sample locations. Brute-force evaluation at N2 spatial locations, of a discrete 2-D Fourier series consisting of N2 modes scales as O(N4) and is prohibitive for image arrays on the order N ≈ 103 and above.. There are three variants of the trigonometric sums to be evaluated by such algorithms. The “Type-2” variant is that in which we sum a set of regular locations in the discrete Fourier domain, to evaluate the inverse transform at an irregular set of locations in the image domain. In other words, it is a method that allows us to use Fourier interpolation, with a relatively large number of DFT modes and a relatively large number of interpolation sites.","PeriodicalId":117250,"journal":{"name":"2009 IEEE Aerospace conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133362378","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}
