چکیده

در این مقاله ابزار "آزمین" معرفی شده است. این ابزار با استفاده از روش مطآ (مدل طراحی آماری) برای طراحی ماهواره‌های مخابراتی زمین آهنگ در آزمایشگاه تحقیقات فضایی طراحی، تهیه و ارائه شده است. ویژگی و هدف اصلی این نرم‌افزار، تعیین مشخصات فنی-مهندسی ماهواره در مدت زمان کوتاه با دقت قابل قبول است. مشخصات در سطح ماهواره شامل جرم، توان، ابعاد و هزینه هستند و در سطح زیرمجموعه شامل جرم، توان و پیشنهاد برای ترکیب المان‌های هر زیرمجموعه می‌باشند. استفاده از این نرم افزار سبب کاهش زمان و به تبع آن هزینه‌، خواهد شد.. در این مقاله سه بخش اصلی نرم افزار آزمین تشریح ‌شده‌ اند. پایگاه داده‌ی مورد استفاده در نرم افزار شامل 462 ماهواره مخابراتی ‏زمین آهنگ‏ از سال 2000 تا 2017 است. پس از تشریح بخش‌های مختلف نرم‌افزار، روابط استفاده شده در آن معرفی شده‌اند. ‏دقت "آزمین" به دو روش پیاده‌سازی و آماری صحه‌گذاری شده است. میانگین خطای نتایج به دست آمده 15% است.

چکیده [English]

This study introduces a new computer code termed AZMIN developed by Space Research Laboratory (SRL). This efficient tool which benefits from the Statistical Design Model (SDM) has been developed for the system design of GEO communication satellites. The main advantage of the AZMIN is to determine technical specification parameters of a satellite at both system and subsystem levels, with a high accuracy and time performance. System-level parameters encompass mass, power, dimension and cost; while, subsystem parameters contain mass, power, and solutions for components configurations of each subsystem. Actual computations of this tool are carried out by means of SDM, leading to a dramatic decrease in the conceptual design time and consequently, its cost. The database utilized is composed of records of 462 GEO communication satellites launched from the year 2000 to 2017. The accuracy of the AZMIN code is amply verified through an example and also a statistical method, demonstrating the mean error of approximately 15% in the obtained results.
