Abstract:
Radiosonde is a balloon-borne device that is used worldwide to measure
several vertical meteorological parameters like temperature, humidity, air pressure,
wind speed, and wind direction at various layers of the atmospheres. TheRadiosonde
is attached to a sounding balloon filled with hydrogenso it elevates easily up to 30 km.
While Radiosondeis ascending from the surface into the stratosphere, it transmits its
measurements to a ground receiving station where they are processed into
temperature, pressure, dew point, humidity, wind speed and direction. Ground
receiving station is responsible for receiving signal from Radiosonde by three
antennas then the ground equipment filters and processes the measurements to be used
by computer software to generate a report that is transmitted as a binary coded
message over the global telecommunication systems (GTS) to various regional and
national meteorological centers around the world.There are more than 1000
Radiosondes are launched every day to obtain data for weather forecasting. Stations
around the world launch two Radiosondes on a daily basis. The EMA is one of the
main users of the Radiosonde as Radiosonde provides essential datafor aviation,
military, and agriculture...etc. However, Egypt imports this device, which costs about
40 million Egyptian pounds annually, putting a lot of pressure on Egypt’s budget.The
proposed system as part of this research aims to overcome the current imported
system drawbacks and weaknesses, improve performance and features, along with the
economic and social benefits from the designing and implementing this device to
serve and satisfy our national and regional needs.
