Disaster Monitoring Constellation Using Nanosatellites

ABSTRACT: In this paper, a constellation of four low earth orbit nanosatellites for disaster monitoring is presented; their small size, low cost, and short time development give them the opportunity to be widely selected. The space segment is based on existing subsystems that are assembled on the bottom part of a developed structure and present acceptable performance for the mission. The payload is a multispectral camera which fulfills the mission's requirements (remote sensing). The ground segment is based on an existing modular ground station, used for the ALSAT-1 DMC, which will be adapted to fit with the specifications of the mission.摘要：本文提出一套用于灾害监测的4颗低地球轨道纳米卫星星座；该星座体积小巧、成本低廉且开发周期短，具备被广泛选用的潜力。空间段基于现有分系统，将其组装于一款已开发结构的下部，可为任务提供符合要求的性能表现。有效载荷（payload）为一台多光谱相机，可满足本次遥感任务的各项需求。地面段基于曾服务于ALSAT-1 DMC项目的模块化地面站，将针对本次任务的技术规格完成适配改造。
