Ionospheric disturbance effect on NNSS satellite positionings at Syowa Station
An experiment for investigating a relation between geomagnetic disturbance and satellite positioning error in the polar region was carried out at Syowa Station, Antarctica, in 1985 and 1986 with a two-wave (150 and 400MHz) NNSS receiver. From the analysis of positioning data of about 10000 passes ov...
