Decoding Weather Satellite Data with G-Predict, Airspy, and RTL-SDR
Middle School (Grades 6-8)
Two 50-minute class sessions
Students will learn about the GOES weather satellites, and how to use G-Predict, Airspy, and an RTL-SDR to receive and decode data transmitted by these satellites. This hands-on lesson will involve setting up the necessary software and hardware, tracking satellites, and interpreting the received data.
Understand the basics of weather satellites, specifically the GOES series.
Learn how to set up and use G-Predict for satellite tracking.
Understand the principles of radio frequency and data transmission.
Gain experience in using Airspy and an RTL-SDR to receive satellite data.
Interpret and analyze the data received from GOES satellites.
Computers with G-Predict and Airspy software installed.
RTL-SDR dongles.
Internet access for research and software downloads.
Projection system for demonstrations.
Introduction to GOES Satellites (15 minutes)
Discuss the purpose and capabilities of GOES satellites.
Explain how these satellites help in weather monitoring and forecasting.
Setting up G-Predict (20 minutes)
Guide students through installing G-Predict (if not already installed).
Demonstrate how to use G-Predict to track GOES satellites.
Introduction to RTL-SDR (15 minutes)
Explain the basics of software-defined radio (SDR).
Show how an RTL-SDR can be used to receive signals.
Setting up Airspy and RTL-SDR (20 minutes)
Demonstrate connecting the RTL-SDR dongle to the computer.
Guide students through setting up Airspy to interface with RTL-SDR.
Receiving Satellite Data (20 minutes)
Instruct students on how to use the setup to receive data from a GOES satellite.
Ensure each student or group has an opportunity to attempt receiving data.
Data Analysis and Discussion (10 minutes)
Discuss the types of data received and what they represent.
Encourage students to share their observations and findings.
Participation in setting up and using the software and hardware.
A short quiz or worksheet on the functions of GOES satellites and the basics of SDR.
Group presentation or report on their experience and the data they received.
Provide links to online resources about weather satellites and SDR.
Suggest projects or experiments students can try at home if they have access to an RTL-SDR.
Ensure students handle the RTL-SDR and any related hardware carefully.
Supervise the use of computers and software to avoid misuse.
By the end of this lesson, students should have a basic understanding of how weather satellite data is transmitted and received, and the practical skills to set up a system to receive such data. This lesson also aims to inspire interest in satellite technology and meteorology.
