Abstract
Earthquakes are among the most significant natural disasters, posing persistent threats to human life. Accurate prediction of these events has long been a major challenge, and numerous efforts have been made to address it. A novel approach that has gained attention in recent years involves the use of CubeSat to monitor ionospheric changes prior to earthquakes. Variations in electron temperature and density within the ionosphere can serve as indicators of pre-seismic activity.
Analysis of data from several similar missions indicates that this method is capable of detecting pre-seismic anomalies with a considerable degree of accuracy. In this study, an initial design of a one-unit CubeSat is presented using a systematic design approach, in which the components and key parameters of each subsystem have been thoroughly examined and evaluated. The results demonstrate that this design framework can provide a cost-effective, precise, and optimized platform for research missions focused on earthquake prediction.
The proposed CubeSat is specifically designed for earthquake prediction through measurements of electron temperature and density. The primary payload was selected for its simplicity and higher measurement accuracy compared to alternative methods. The design process encompasses mission definition and analysis, system engineering, and the development of payloads and subsystems

Abstract Persian

زلزله یکی از مهم‌ترین بلایای طبیعی به شمار می‌آید که همواره تهدیدی جدی برای انسان‌ها ایجاد می‌کند. پیش‌بینی دقیق این پدیده از چالش‌های اساسی بشر بوده و تاکنون تلاش‌های متعددی برای دستیابی به آن صورت گرفته است. یکی از رویکردهای نوین که در سال‌های اخیر مورد توجه قرار گرفته، بهره‌گیری از ماهواره‌های کوچک، برای پایش تغییرات لایه‌ی یونوسفر پیش از وقوع زلزله است. تغییرات دما و چگالی الکترون در این لایه می‌تواند به‌عنوان شاخصی از فعالیت‌های پیش‌زلزله‌ای مورد استفاده قرار گیرد.
نتایج بررسی داده‌های چند مأموریت مشابه نشان می‌دهد که این روش قادر است ناهنجاری‌های پیش‌زلزله‌ای را با دقت قابل‌قبولی شناسایی کند. در این مقاله، طراحی اولیه یک ماهواره مکعبی یک‌واحدی با رویکرد سیستمی ارائه شده است، به‌گونه‌ای که در هر زیرسیستم، اجزا و پارامترهای کلیدی موردنیاز برای طراحی بررسی و تحلیل شده و مقادیر عددی مربوط به آن‌ها ارزیابی گردیده است. نتایج حاصل نشان می‌دهد که این چارچوب طراحی می‌تواند گامی مؤثر در جهت ساخت یک نانوماهواره یک‌واحدی مقرون‌به‌صرفه، دقیق و بهینه برای تحقیقات مرتبط با مأموریت پیش‌بینی زلزله شود.
در این پژوهش، طراحی اولیه یک ماهواره مکعبی یک واحدی با مأموریت پیش‌بینی زلزله از طریق اندازه‌گیری دما و چگالی الکترون ارائه شده است. محموله اصلی این ماهواره مکعبی به دلیل سادگی ساختار و دقت بالاتر نسبت به سایر روش‌ها انتخاب شده است. فرایند طراحی شامل تعریف و تحلیل مأموریت، مهندسی سیستم، طراحی محموله و زیرسیستم‌ها است.
