Abstract

Advanced technology has unlocked new opportunities for the rapidly growing satellite industry. The design of seismic satellite is a novel technology and has very challenges. The primary objective of a seismic satellite system is to monitor and quantify electromagnetic pre-seismic signals within Earth's atmospheric layers, with a particular focus on the ionosphere. These signals are detectable via specialized radiometric sensors and radio frequency wave analysis. This paper presents a novel system and subsystem-level test model for a seismological satellite, including its Electrical Ground Support Equipment (EGSE). The EGSE serves as a critical test platform to ensure full compatibility before and after subsystem integration. It verifies satellite performance through multi-level testing by simulating electrical interfaces between onboard systems and communication modules. The qualification process is conducted at the subsystem and system levels using both engineering model and flight model. Following environmental testing, the satellite undergoes a comprehensive final functional test to confirm mission readiness. The proposed test model validates critical subsystems, including power, attitude control, communications, on-board data handling, and payload, as well as overall system integration. The test platform is designed in accordance with European cooperation for space standardization protocols to guarantee compliance with space-grade reliability standards.

Abstract Persian

فناوری‌های پیشرفته، فرصت‌های نوینی را برای صنعت پرشتاب ماهواره‌ای گشوده‌اند. هدف اصلی یک سیستم ماهواره‌ای لرزه‌نگاری، پایش و سنجش سیگنال‌های الکترومغناطیسی پیش‌لرزه‌ای در لایه‌های جوّ زمین با تمرکز ویژه بر یونوسفر است. این سیگنال‌ها به‌کمک حسگرهای رادیومتریک تخصصی و تحلیل امواج رادیویی قابل تشخیص هستند.

این مقاله، یک مدل آزمون در سطح سیستم و زیرسیستم را برای یک ماهواره لرزه‌شناختی، همراه با تجهیزات پشتیبانی زمینی الکتریکی (EGSE) آن ارائه می‌دهد. EGSE به عنوان یک سکوی آزمون حیاتی عمل می‌کند تا سازگاری کامل را قبل و بعد از تجمیع زیرسیستم‌ها تضمین کند. این سامانه، عملکرد ماهواره را از طریق آزمون‌های چندسطحی و با شبیه‌سازی رابط‌های الکتریکی بین زیرسیستم‌های داخلی و ماژول‌های ارتباطی، مورد تأیید قرار می‌دهد.

فرآیند صلاحیت‌سنجی در سطوح زیرسیستم و سیستم و با استفاده از هر دو مدل مهندسی و مدل پروازی انجام می‌پذیرد. پس از آزمون‌های محیطی، ماهواره یک آزمون عملکردی نهایی و جامع را پشت سر می‌گذارد تا آمادگی آن برای انجام مأموریت تأیید گردد. مدل آزمایشی پیشنهادی، زیرسیستم‌های اصلی از جمله منبع تغذیه، کنترل وضعیت، مخابرات، پردازش داده‌های روی‌برد و محموله، و همچنین سیستم کلی ماهواره را اعتبارسنجی می‌کند. در این طراحی کلیه آزمون‌ها و مراحل آن مطابق با پروتکل‌های استاندارد اروپایی برای استانداردسازی فضایی (ECSS) اجرا می‌شوند تا قابلیت اطمینان سیستم در درجه فضایی تضمین شود.
