本文系统地研究了基于“北斗一号”卫星载波相位干涉测量原理实现地球静止双星定向的相关技术,主要研究成果包括以下几方面:首先,建立了利用两颗地球静止轨道卫星进行短基线定向的数学模型,分析了载波相位干涉测量的适用条件;采用传统的线性化解析法及蒙特卡洛随机模拟法两种途径对双星定向的精度进行了详细分析,数学仿真结果表明在高纬度地区线性化解析法由于俯仰角误差分析精度略有下降而不太适合;在分析定向精度确定性影响因素的基础上,提出了双星定向精度衰减因子odop的概念,揭示了双星定向误差特殊表现的内部机理,对实际工程应用具有重要的指导意义。 - Then the unified approach can be applied to it to acquire the ensemble random evolutionary response . since the normal probability density function ( pdf ) may lead to instability of some sample systems when the random parameters taking sufficiently small negative values , an arch - like pdf and a more adaptable - pdf , together with the matching chebyshev polynomial approximation and gegenbauer polynomial approximation , are suggested . numerical examples show that the suggested methods are effective
相比较而言，随机模拟法的结果无疑是最可靠的，但是它的计算量嫌大；随机摄动法的计算量远小于随机模拟法，但是它要求随机摄动量必须是一个小量；正交展开法的计算精度好于随机摄动法，其得到结果与随机模拟法得到的结果几乎吻合，其计算量略多于随机摄动法，但与随机模拟法相比要少的多，不过计算前的准备工作较费时。
