This paper presents an overview of the research activities undertaken by La Salle and the Ebro Observatory in the field of remote sensing. On 2003 we started a research project with two main objectives: implement a long-haul oblique ionospheric sounder and transmit the data from remote sensors located at the Spanish Antarctic station Juan Carlos I to Spain. The paper focuses on a study of feasibility of two possible physical layer candidates for the skywave link between both points. A DS-SS based solution and an OFDM based solution are considered to achieve a reliable low-power low-rate communication system between Antarctica and Spain.
本文概述了拉萨尔大学和埃布罗天文台在遥感领域开展的研究活动。2003 年，我们启动了一个研究项目，其主要目标有两个：实施远程斜向电离层探测仪，并将位于西班牙南极站胡安·卡洛斯一世的远程传感器的数据传输到西班牙。本文主要研究两点之间天波链路的两种物理层候选方案的可行性。基于直接序列扩频（DS-SS）和正交频分复用（OFDM）的解决方案被认为是在南极洲和西班牙之间实现可靠的低功率、低速率通信系统的方法。
