Sistem Telemetri pada Payload Radiosonde Secara Real Time dengan Komunikasi Wireless

Abstract

In predicting the weather, there are many parameters used. In addition, the speed in getting these parameters to be ignored. Therefore, retrieval of weather data in real time is needed. This study aims to predict the weather in real time and save the data. In measuring weather parameters, there are many ways to get it, one of which is a radiosonde. That is a measuring device with weather parameters flown a balloon with helium gas. At the time of the radiosonde is in the air, sending air parameters via radio waves with a frequency of 433Mhz. 433Mhz frequency selection because besides resistant to weather disturbances, this frequency is also a provision of the committee Komurindo -Kombat 2016. After transmitted over radio waves, the data is immediately displayed in the GUI (Graphic User Interface) and saved in *.txt format which is also determined by Komurindo-Kombat 2016 committee. the result showed radiosonde work well with the stability of experimental data transmission up to 95%. 5% error due to his existing radio wave interference. Interference caused by obstacle that exists between payload with Ground Segment (GS).
