Optimum parameter for estimating phase fluctuations on transionospheric signals at high latitudes

Data from a GPS scintillation monitor based on 50 Hz measurements recorded at Dirigibile Italia Station (Ny­Alesund, Svalbard), in the frame of the ISACCO project are used to investigate possible adoption of an alternative parameter for the estimate of phase fluctuations: i.e., the standard deviation of the phase rate of change S_phi.

Observations of the atmospheric boundary layer across the land-sea transition zone using a scanning Mie lidar

Optical properties of the atmospheric boundary layer (ABL) above the land­sea transition interface were measured using a scanning Mie lidar at a location 30km from the Adriatic coast. Based on the 2­-dimensional range­height­-indicator scans, detailed information on the ABL was obtained, including parameters such as atmospheric optical depth, aerosol extinction coefficient and the height of the ABL.

Tackling ionospheric scintillation threat to GNSS in Latin America

Analysis presents initial results from a research work aimed to tackle ionospheric scintillation effects for GNSS users in Latin America. This research is a part of the CIGALA project, co-funded by the EC Seventh Framework Program and supervised by the GNSS Supervisory Authority (GSA), which aims to develop and test ionospheric scintillation countermeasures to be implemented in multi-frequency, multi-constellation GNSS receivers.
