Autonomous Lunar Orbit Determination using Star Occultation Measurements
A method has been developed for performing autonomous Lunar orbit determination based on measurements of the times at which stars set behind or rise above the Lunar limb. This system is being developed as a possible technology for use in the Lunar exploration initiative because it enables increased autonomy of operations near the Moon. The system consists of a specially modified star camera and...

شبکه خود سازمانده پرکاربردترین شبکه عصبی برای انجام خوشه بندی و کوانتیزه نمودن برداری است. از زمان معرفی این شبکه تاکنون، از این روش در مسائل مختلف در حوزه های گوناگون استفاده و توسعه ها و بهبودهای متعددی برای آن ارائه شده است. شبکه خودسازمانده از تعدادی سلول برای تخمین تابع توزیع الگوهای ورودی در فضای چندبعدی استفاده می کند. احتمال وجود سلول مرده مشکلی اساسی در الگوریتم شبکه خودسازمانده به حسا...
A new wavelet - based approach for the automated treatment of large sets of lunar occultation data ⋆
Context. The introduction of infrared arrays for lunar occultations (LO) work and the improvement of predictions based on new deep IR catalogues have resulted in a large increase in the number of observable occultations. Aims. We provide the means for an automated reduction of large sets of LO data. This frees the user from the tedious task of estimating first-guess parameters for the fit of ea...
متن کاملThe Lunar Occultation Observer (loco) - a Nuclear Astrophysics All-sky Survey Mission Concept
Introduction: The Moon is a unique location for experimental astrophysics. It’s dense regolith and lack of an appreciable atmosphere are just two of the characteristics that can be brought to bare on the challenges of high-energy astrophysics. The Lunar Occultation Observer (LOCO) is a new γ-ray astrophysics mission concept expected to have unprecedented sensitivity in the nuclear regime (~0.02...
متن کاملAn investigation of the multiple star Zeta Cnc by a lunar occultation
We analyze and discuss a lunar occultation of the multiple star ζ Cnc, obtained in the near-infrared. The longsought D component, recently imaged with the help of adaptive optics also by Hutchings et al. (2000), is clearly seen in the occultation light curve, and we determine its projected separation and brightness ratio with high accuracy. Regarding the suggested binary nature of D, we provide...
