Chilbolton Global Broadcast System

GBS beacon receiver.


Clouds and rainfall along a single slant path can result in signal fading for satellite communication systems. The GBS uses Ka-band measurements to observe slant path propagation characteristics and to demonstrate and predict the impact the atmosphere has on signal strength. Linking two or more satellite ground stations together, system operators can use this technique to mitigate signal fading and observe site diversity at Ka-band wavelengths. By combining these results with data from the main meteorological radar CAMRa, the influence of the variation of raincells over time and space on the orientation and separation of satellite ground stations can be observed.

Data format

Data are available form the Chilbolton and Sparsholt sites from 19th August 2003 and 8th October 2003 respectively.

The files are in NetCDF format.

Conditions of use

If Chilbolton GBS data is used in any publication or report then acknowledgement must be given to the Radiocommunications Research Unit at the Rutherford Appleton Laboratory for providing the data.

Who to contact

If you have problems obtaining the data, please contact the British Atmospheric Data Centre.
