Abstract:	Ionospheric scintillation and GPS data were collected over 108 days (from August 15 to November 30, 2001) at two sites in Japan -- Naha and Mitaka/Tokyo. The data consisted of 1-sec reports from dual-frequency GPS receivers and 1-min reports from single frequency Ionospheric Scintillation Monitors (ISMs). In addition, there were several days of 50 Hz ISM data (5 days in November 2001, and 3 days in March 2002). The ISM receiver produced estimates of intensity (amplitude) and phase scintillation at L1, which were correlated with the loss of lock on L2 from the GPS receiver. Results show that, Mitaka (Tokyo) does not have a serious scintillation problem as expected because it is located in the mid-latitudes. However, Naha which is located under the northern anomaly region, has a significant scintillation problem which causes loss of lock on signals from GPS satellites, including loss of lock on several satellites simultaneously.
