Integrated High Speed and High Capacity Base-Band Data Handling—Solid-State Recorder for Small Satellite Applications

Abstract

Defense satellites with hyperspectral imaging (HSI) and synthetic-aperture radar (SAR) payloads capture high-resolution images. The voluminous data captured by payload needs to be processed and stored for transmission to ground station upon visibility for analysis. Data from payloads has to be acquired by data handling system and to be stored in memory after required processing. This paper describes novel and efficient hardware architecture of high speed, high capacity, miniaturized, non-volatile, redundant and radiation tolerant integrated base-band data handling (BDH)—solid-state recorder (SSR) system for polar lower earth observation (LEO) small satellite applications.
