Abstract
Satellite constellations consist of similar satellites distributed in a specific orbital pattern to accomplish a joint mission. They are commonly used for global telecommunications, positioning, and remote sensing missions. This article utilizes a scientometric approach to analyze the structure and scientific mapping of "satellite constellations" worldwide, focusing on two leading countries: the United States and China. Additionally, a comparison is made between the United States, China, and global research outputs.The research encompasses all scientific documents in the "satellite constellations" field indexed in the Scopus database from 1969 to 2023. Knowledge maps (thematic subfields) and international cooperation maps are generated using Bibexcel and VOSviewer software. The number of documents published in this period includes 14,346 globally, with 3,738 from the United States and 3,369 from China.The findings reveal that the United States, China, Germany, Italy, and the United Kingdom are leaders in this field. The trend of scientific production in this area is increasing globally, indicating its importance and attractiveness. Conference papers constitute the most significant number of publications worldwide and in the United States, whereas, in China, most documents are journal articles. The top scientific production institutions globally include the National Aeronautics and Space Administration (NASA), the Chinese Academy of Sciences, the German Aerospace Center, Wuhan University, and the European Space Research and Technology Centre.

Abstract Persian

منظومه‌های ماهواره‌ای شامل مجموعه‌ای از ماهواره‌های مشابه هم می‌باشند که به‌منظور به انجام رساندن یک ماموریت مشترک در یک الگوی مداری خاص توزیع شده‌اند. از منظومه‌های ماهواره‌ای معمولاً برای به انجام رساندن ماموریت‌هایی مانند مخابرات جهانی، موقعیت‌یابی جهانی و سنجش از دور استفاده می‌گردد. در این مقاله با به‌کارگیری رویکرد علم‌سنجی به تحلیل و ترسیم ساختار و نقشه‌های علمی حوزه «منظومه‌های ماهواره‌ای» در جهان و همچنین دو کشور پیشرو شامل آمریکا و چین بر مبنای تعداد اسناد پژوهشی منتشر شده در این حوزه پرداخته شده است. علاوه بر این، مقایسه‌ای بین این دو کشور با کل دنیا نیز صورت گرفته است. جامعة پژوهش شامل کلیة مدارک علمی در حوزه «منظومه‌های ماهواره‌ای» است که در پایگاه «اسکوپوس» مابین سال‌های 1969 تا 2023 میلادی نمایه شده‌اند. همچنین در این مقاله به ترسیم نقشه‌های دانشی (زیرحوزه‌های موضوعی) و نقشه همکاری‌های بین‌المللی کشورها با استفاده از نرم‌افزارهای Bibexcel و VOSViewer نیز اقدام شده است. تعداد مدارک منتشر شده در این دوره زمانی در جهان، آمریکا و چین به ترتیب شامل 14346، 3738 و 3369 مدرک می‌باشد. یافته‌های پژوهش نشان می‌دهد که کشورهای آمریکا، چین، آلمان، ایتالیا و انگلستان، بیشترین میزان تولیدات علمی در این حوزه را به خود اختصاص داده‌اند. همچنین روند تولید علم در این حوزه در جهان صعودی است که نشان‌دهنده اهمیت و جذابیت این حوزه علمی است. از منظر نوع مدارک منتشر شده نیز مقالات همایشی بیشترین میزان مدارک منتشر شده در جهان و کشور آمریکا را به خود اختصاص داده‌اند؛ درحالی‌که بیشترین میزان مدارک منتشر شده در کشور چین مربوط به مقالاتی است که در مجلات به چاپ رسیده‌اند. نهادهای برتر تولید علم در این حوزه در جهان نیز به ترتیب شامل اداره کل ملی هوانوردی و فضا (ناسا)، آکادمی علوم چین، مرکز هوافضای آلمان، دانشگاه ووهان و مرکز تحقیقات و فناوری فضایی اروپا می‌باشند.
