At $20 the rtlsdr is pretty much the cheapest NOAA APT / satellite communication receiver I have ever had.Necessary cookies are absolutely essential for the website to function properly. I hope this demonstrates that RTL SDR devices do have practical applications. You can now clearly see the landmass and the clouds, as well as the reflection of the Sun on the surface of the ocean. Below I have a “HVC false color” image where I have also applied histogram equalization: Wxtoimg can combine the different images to create various false color images. On the image above we see the infrared image on the left and visible light on the right. Often, one channel will contain a visible light image and the other will contain and infrared image. This is the image decoded by wxtoimg with the “contrast enhancement” option:ĪPT transmissions from the NOAA weather satellites contain two channels that are basically two images from two different instruments. If you can make it work on your Linux box, it will provide you with many options for processing and enhancing the received APT images.

Wxtoimg is a commercial APT decoder, however, it comes with a limited free version. The image was captured during a late afternoon pass, which is a good time for APT reception, because we can often see shadows beneath the clouds, giving the image a sense of 3D. Here is what I got from the recording of the NOAA-15 pass: It can decode the image but I have problems getting false color and temperature to work.

The easiest and fastest way to resample the audio is using sox: sox input.wav output.wav rate 11025Ītpdec (probably misspelled version of aptdec) is an open source APT decoder which is no longer maintained. Recordings show multiple tracks and decode report shows telemetry data not found. Use a sample rate that works well with your device on your computer (I used 1024 ksps). Decode the image from the audio using atpdec or wxtoimg. The signal level in WxToImg as sent by VB Cable from an RTL-SDR USB dongle suddenly went from nearly always green and acceptable for clean images (mostly) to yellow and red, 100. With the latest rtl-sdr I had to use max gain setting.Use a sample rate that works well with your device on your computer (I used 1024 ksps).With the latest rtl-sdr I had to use max gain setting. Use the proper FM deviation (17 kHz) and filter width (45 kHz).During this experiment I have used my Arrow II satellite antenna however, for a permanent installation a Quadrifilar Helix or a Turnstile antenna would be better.Īs written in the Funcube Dongle article, the procedure is to:

I suspect the recent gain improvements in the driver have something to do with it. Lets start with a video showing Gqrx receiving the APT transmission from the NOAA-15 polar orbiting weather satellite during orbit 73676 over western Europe:Īs you can see both the baseband and the audio SNR is rather good. Today, I tried to repeat the procedure using my ezcap eztv666 rtlsdr dongle with very good results.

About a year ago I posted a step-by-step guide about how to receive NOAA APT weather satellite images using Gqrx SDR and the Funcube Dongle.
