地磁干扰条件下GPS性能的退化
Degradation of GPS performance in geomagnetically disturbed conditions
摘要：
在地磁干扰的条件下，GPS的性能会受到损害。在三种主要类型（ASHTECH、TRIMBLE和AOA）的双频GPS接收机工作的情况下，定位精度的均方根误差增加。对于ASHTECH接收器（与AOA和TRIMBLE不同），单频和双频定位模式的滑移密度与地磁扰动水平之间也有明显的相关性。
英文摘要：
The GPS performance is impaired in conditions of geomagnetic distrubances. The rms error of positioning accuracy increases in the case where two-frequency GPS receivers of three main types (ASHTECH, TRIMBLE, and AOA) are in operation. For ASHTECH receivers (unlike AOA and TRIMBLE) there is also a clear correlation between the slip density of the one- and two-frequency modes of positioning and the level of geomagnetic disturbance.
