This paper describes methods for modelling decision variables, for enroute flight planning under Visual Flight Rules (VFR). For demonstration purposes, the task of delivering a medical package to a remote location was chosen. Decision variables include fuel consumption, flight time, wind and weather conditions, terrain elevation, airspace classification and the flight trajectories of other aircraft. The decision variables are transformed, using a Multi-Criteria Decision Making (MCDM) cost function, into a single cost value for a grid-based search algorithm (e.g. A*). It is shown that the proposed system provides a means for fast, autonomous generation of near-optimal flight plans, which in turn are a key enabler in the operation of UAVs in the NAS.","PeriodicalId":117250,"journal":{"name":"2009 IEEE Aerospace conference","volume":"83 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":"121708171","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}

One unique feature of this design is that two common-mode feedback circuits were employed to control both the input stage and output stage independently. Regulating the common-mode level between the input and output stages produced better stability over temperature for each stage. Special considerations were taken in the layout to increase the immunity of latch-up and noise and decrease mismatch. The BiCMOS amplifier described successfully demonstrates the use of the commercially available IBM SiGe 5AM process to produce reliable operation in extreme temperature and radiation environments.","PeriodicalId":117250,"journal":{"name":"2009 IEEE Aerospace conference","volume":"577 1 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":"122716274","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 testbed combines eight beams of infrared light, four from the star and four from the planet, simulating an ‘Xa-rray’ telescope spacecraft formation. The detection process involves stable nulling of the starlight, rotation of the spacecraft formation, averaging over a few hours and testing of the signal against predicted exoplanet signatures. The testbed simulates all parts of the detection process except operation in broadband light, which is a planned upgrade for the future. This paper describes the latest results and plans for exoplanet signal simulation, deep starlight nulling and planet detection at star to planet contrast ratios of one million to one. These results are planned to demonstrate the feasibility of exoplanet detection using nulling interferometry at near-flightlike contrast ratios.","PeriodicalId":117250,"journal":{"name":"2009 IEEE Aerospace conference","volume":"144 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":"123925795","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}

During its mission it has dug numerous trenches in the Martian regolith, acquired samples of Martian dry and icy soil, and delivered them to the Thermal Evolved Gas Analyzer (TEGA) and the Microscopy, Electrochemistry, and Conductivity Analyzer (MECA). The RA inserted the Thermal and Electrical Conductivity Probe (TECP) into the Martian regolith and positioned it at various heights above the surface for relative humidity measurements. The RA was used to point the Robotic Arm Camera to take images of the surface, trenches, samples within the scoop, and other objects of scientific interest within its workspace. Data from the RA sensors during trenching, scraping, and trench cave-in experiments have been used to infer mechanical properties of the Martian soil.

It takes a huge amount of energy to be put objects in HEO. To provide similar benefits at a very low cost, the ‘Special Orbit’ was offered as an alternate. This paper examines the usability of launching a Hybrid control enabled multiple payload micro satellite in to elliptical orbit. The perigee and apogee distances are modified so that the orbital period is 1/3 of a day instead of 12 hours. This orbit provides the benefits of both low and medium altitudes. In addition to this the orbit doesn't require any onboard liquid fuel or thrusters as there is no orbit manoeuvres required in its mission time. Ground Simulations are done for various initial conditions and time of availability over targets is evaluated.","PeriodicalId":117250,"journal":{"name":"2009 IEEE Aerospace conference","volume":"7 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":"126029864","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}
