Wireless Datalink for Unmanned Aircraft Systems: Requirements, Challenges and Design Ideas
The key challenges in the design of datalinks for UAS systems compared to other wireless links is the long range of distances and speeds that need to be covered. The amount of spectrum available in the L-Band is not sufficient to support video applications common in UASs and so dual-band designs using both L-Band and C-Band are being considered. For LBand, two projects funded by EUROCONTROL L-B...

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولHuman Challenges in the Maintenance of Unmanned Aircraft Systems
Executive Summary Human error will pose a threat to the operation of Unmanned Aerial Vehicles (UAVs), just as it does in other fields of aviation. If UAVs are to be permitted to operate in the National Airspace System (NAS), it will be necessary to understand the human factors associated with these vehicles. Rather than eliminating the potential for human error, the removal of the on-board pilo...
متن کاملChoosing Replanning Strategies for Unmanned Aircraft Systems
Unmanned aircraft systems use a variety of techniques to plan collision-free flight paths given a map of obstacles and nofly zones. However, maps are not perfect and obstacles may change over time or be detected during flight, which may invalidate paths that the aircraft is already following. Thus, dynamic in-flight replanning is required. Numerous strategies can be used for replanning, where t...
