Paper Abstract

The possibility of using high-data-rate optical transmitters for satellite communication has generated interest in laser communication systems for ground-to-space and space-to-ground data links. Among the parameters useful to model propagation along a vertical path are the refractive index structure constant Cn2 profile and boundary layer turbulent strength. One of the most widely used turbulent models is the Hufnagel-Valley (HV) which depend on vertical wind profile and integrated turbulence along the propagation path. We have developed a statistical studied of the input parameters above Canary Island Observatories using a metereological database to collect the wind profiles and DIMM database to evaluate zero order moment. We are estimated the isoplanatic angle and the down-link scintillation. To check the consistency of the model, we are compared the isoplanatic results with isoplanatic angle measured by SCIDAR campaigns (17 nights along the year). To establish the average turbulence wind speed, we are used an observational correlation finds by Sarazin at other high mountain observatories.
