Abstract

In small satellite communications systems, Software Defined Radios (SDR) have been used for increase the system flexibilization both in the space segment and on the ground station implementations. In this paper, an SDR implementation for the space segment is proposed in order to optimize the communication system designed for the Low Earth Orbit (LEO) environment observation satellite (Ten-Koh). This optimization consists in the integration of a Raspberry Pi module and a LimeSDR-mini RF module using embedded Linux, Python and GNU radio tools. The Ten-Koh mission, communication system architecture, on-orbit mission constraints and issues will be described in order to be compared with the proposed optimization to demonstrate the improvements in terms of performance, flexibility and developing time. The purpose is to demonstrate that the proposed system can be replaced safely in future satellite missions similar to Ten-Koh meeting the mission requirements.

Özet

Küçük uydu haberleşme sistemlerinde, Yazılım Tanımlı Radyolar (YTR) hem yer istasyonlarındaki hem de uzay sistemlerindeki uygulamaların sistem esnekliklerini arttırmakta kullanılmıştır. Bu çalışmada, düşük dünya yörüngesindeki çevre gözlem uydusu Ten-Koh için tasarlanan haberleşme sistemi kullanılmış ve uydu üzerindeki sistemin optimizasyonu amacıyla YTR uygulaması önerilmiştir. Bu optimizasyon çalışması, gömülü Linux, Python ve GNU radyo araçlarını kullanan Raspberry Pi ve LimeSDR-mini RF modüllerini içermektedir. Optimizasyon çalışması sonucunda görülen performans, esneklik ve geliştirme süresi iyileşmeleri açıklanarak, Ten-Koh görevi, haberleşme sistem mimarisi, yörüngedeki görev kısıtlamaları ve sorunları ile karşılaştırmada kullanılmıştır. Bu çalışmadaki amaç, önerisi yapılan sistemin Ten-Koh görevine benzeyen gelecekteki uydu sistemlerinde kullanılabileceğini göstermektir.
