Design and Implementation of RadiosondeIntegrated System (Ground Station)

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.
