【摘要】

：

本文从GDOP与星座几何布局的关系出发,结合实际应用场景,提出了有效仰角阈值自适应分阶选星算法.该方法以满足定位要求为前提,基于可见星仰角来初筛卫星,对不同仰角卫星进行合理的取舍,以卫星均匀分布为原则,将在理想情况和实际情况下寻找有效定位平衡点,以规避无效选星并减少计算量,从而大大减少选星时间,有效实现了在组合定位中快速选星.

BDS/GPS单历元算法用于云南桥梁形变监测研究

在GNSS桥梁监测中由于桥身的遮挡,GNSS信号经常中断、周跳发生频率较高,若采用常规的OTF算法进行动态监测需频繁初始化,通常避开周跳探测,采用单历元算法进行定位解算,以获取高精度形变信息.本文利用BDS/GPS组合单历元算法进行云南桥梁监测研究.结果表明:1)BDS单系统与GPS单系统监测精度相当,并且由于BDS卫星数多于GPS卫星数,BDS监测精度略优于GPS;2)BDS/GPS组合单历元监

多系统交互式增强导航方法研究

贝叶斯理论在数据融合方面获得广泛应用,而源于贝叶斯理论的融合算法也层出不穷.本文将贝叶斯理论引入到基于卡尔曼滤波的多系统融合定位中.该算法将系统之间的变化关系,用一阶马氏链来描述.利用先验概率和贝叶斯理论计算出系统之间的混合概率,并在滤波前进行各个系统之间的混合,然后进行并行滤波,滤波后依据卡尔曼滤波所获得的新息计算各系统在融合定位中的概率,依据此概率进行多系统定位结果的融合,并将各系统概率和滤波
