摘要
航天测控站配备的传统的卫星模拟器功能单一,通用性差,已经不能满足目前卫星发展的多种测控体制、多种卫星平台的实际需求。为满足这一需求,研究了一种基于软件无线电技术的通用卫星模拟器,在70 MHz中频上进行数字化处理,实现了多体制、多星共用的功能。该卫星模拟器具有体积小、精度高、稳定性好、操作维护简单的特点。
As the conventional satellite simulator has simple function and bad universalness,it can not adapt the needs of multi-TT＆C system and multi-satellite platform.In order to solve the problem,a new satellite simulator based on software radio theory is designed that adopted the 70MHz IF digitized approach to suit the needs.This satellite simulator has the advantages of small size,high precision,well stability and easy use.
