| 摘 要： | 面对空间环境监测日益增多的需求,而常用的接收、跟踪定位设备却比较笨重且灵活性差,不能满足既机动灵活又适合于多种场合的要求.据此提出了一种基于时差定位(TDOA)的探空火箭定位方法及约束加权最小二乘定位算法.该方法具有接收可靠、移动灵活、定位精度高、成本低等特点,可用于多种场合的探空火箭定位、数据接收和处理.

| Abstract: | The requirements of space environment exploration are increasing,but usual receiving and tracking equipment are ponderous and with bad agility,and more and more unsuitable for multi-purpose situation,in which more flexibilities are needed.Locating methods based on time difference of arrival are presented by sounding rocket,and a constrained weighted least squares location algorithm is given.The methods have the characteristics of reliable receiving,good agility, high locating precision and low cost.And the methods can be used to locate sounding rocket,receive and process the exploring data for multi-purpose situation. |
