چکیده

در شرایط اورژانسی که امکان استفاده از بسترهای مخابراتی زمینی یا فضایی وجود ندارد و یا در شرایطی که نیاز به برقراری ارتباطی مخابراتی در مناطقی دورافتاده که فاقد بسترهای مورد نیاز مخابراتی هستند وجود دارد، به طور معمول از فناوری بالن‌های مقید برای تبادل اطلاعات استفاده می‌گردد. فناوری بالن‌های مقید علی‌رغم تمام مزایایشان، دارای عیب قابلیت پوشش‌دهی منطقه‌ای کوچک هستند. در این مقاله، به منظور بهره‌گیری همزمان از مزایای بالن‌های مقید و پوشش‌دهی یک منطقه‌ی وسیع، استفاده از یک بالن مجهز به مکانیزم نشانه‌روی آنتن پیشنهاد شده و به مدل‌سازی سینماتیکی و دینامیکی مکانیزم پیشنهادی پرداخته شده است. در این کار مدل سینماتیکی استخراج شده توسط نرم‌افزار‌ RoboAnalyzer و همچنین تولباکس Robotics از نرم‌افزار MATLAB مورد اعتبارسنجی قرار گرفته است. مکانیزیم مدل‌سازی شده قابلیت دوران در دو جهت قوس‌افقی و قوس‌عمودی را برای آنتن فراهم می‌آورد و بدین ترتیب ناحیه تحت پوشش آنتن را به طور چشمگیری افزایش می‌دهد.
