Development of on-board engineering model for 920-MHz earth sensing platform via LEO satellite utilizing feeder-link MIMO technology

Abstract

We are currently developing a 920-MHz earth sensing platform via a low Earth orbit (LEO) satellite utilizing feeder-link multiple-input multiple-output (MIMO) technology. This platform aims to lower the cost of earth sensing service via satellite by making use of terrestrial low-power wide-area (LPWA) terminals and shared unlicensed frequency bands. In this paper, we introduce the on-board engineering model we developed for the satellite experiments as well as our earth sensing platform concept.
