GRAW Radiosonde launch station (DFM-90, GS-E): Specialized launching site for the deployment of meteorological GRAW radiosondes with attaching capabilities of newly developed atmospheric electricity sensors. The used radiosondes are of the DFM-09 type, are extremely light, small and robust, and provide reliable measurements of core atmospheric parameters with a columnar distribution. Effective telemetry and optimum reception guaranteed by the GS-E groundstation, make it the ideal set-up for on demand launches.
