GOES Weather Satellite

Lesson Title:

Decoding Weather Satellite Data with G-Predict, Airspy, and RTL-SDR

Grade Level:

Middle School (Grades 6-8)

Duration:

Two 50-minute class sessions

Lesson Overview:

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.

Learning Objectives:

• 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.

Materials Needed:

• Computers with G-Predict and Airspy software installed.

• RTL-SDR dongles.

• Internet access for research and software downloads.

• Projection system for demonstrations.

Session 1: Introduction and Setup

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.

Session 2: Receiving and Analyzing Data

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.

Assessment:

• 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.

Additional Resources:

• 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.

Safety Considerations:

• 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.
