Degradation of GPS performance in geomagnetically disturbed conditions


الملخص بالإنكليزية

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.
