Abstract:
This project-based research focuses on detecting and analyzing signals from polar-orbiting
weather satellites using software-defined radio (SDR) technology. Polar-orbiting weather
satellites, such as transmit weather-related data via VHF radio frequencies ( 137 MHz)
as they traverse north-to-south or south-to-north orbits. These signals can be captured
using an SDR receiver, a circular polarized antenna, and a computer system to process the
received signal. The captured signals are processed with software to record the incoming
data. Thats why it called Software Defined Radio. This recorded audio is then decoded
using another software based on which types of data captured and later producing satellite weather images. These images provide valuable insights into cloud cover, temperature
distribution, and other meteorological phenomena, offering significant potential for further
research in weather analysis, climate monitoring, and environmental studies. This project
also analize two types of circular polarized antenna. The two different setup on antenna
system can show which is better for this particular geo-location. This project-based research demonstrates how affordable, accessible tools can be employed to decode real-time
satellite data into actionable imagery. The approach also highlights the feasibility of independent satellite signal research, contributing to educational and scientific endeavors.
The findings and methodologies outlined in this project-based research pave the way for
broader applications in atmospheric science, disaster management, and sustainable development.
