Abstract:	A modification has been made to the TurboRogue GPS receiver to monitor and characterize the effects of ionospheric scintillation on GPS signals. The modified receivers are capable of calculating and recording single frequency (L1) scintillation indices simultaneously from 8 channels, in conjunction with producing the standard dual frequency GPS observables. A PC-based procedure has also been developed to collect the index data as well as calculate and store phase and amplitude power spectra from 50 Hz sampled data from a single channel. This ionospheric scintillation monitoring system (ISMS) can autonomously collect and record standard dual-frequency GPS observables, scintillation indices and spectra, and high sampling rate data (50 Hz) for detailed analyses of scintillation effects. Sponsored by the Federal Aviation Administration, the ISMS is being implemented at selected sites of the IGS global GPS network at low, middle and high latitudes. This paper describes the development, test, implementation, and operation of ISMS.
