If you see something like this at first don’t be discouraged! Those vertical bars in the middle and sides indicate that you are receiving transmissions from a satellite. Note that the map overlay is added in post. Below is an image I received on a pass with a 9-minute duration, which was clearly too low in the sky to be useful given my setup. The longer the duration, the higher the maximum angle, the better your image.
For your first go it’s best to pick a pass where the satellite will be in the sky for at least 11:30 - there’s a positive relationship between this duration and the maximum angle that the satellite makes with the horizon as it passes. This will result in the least amount of noise in your image. With the antenna we’re going to use later on you want the satellite to be as close to directly overhead as possible. Check under “Local Time” to see when the next one will occur!Īn important thing to note here is the duration and altitude listed. A window similar to the one above should appear with the times of the satellite passes for the next week. Click on File->Update Keplers, then select File->Satellite Pass List. The first thing you’ll want to check out is the satellite flyover list.
#WXTOIMG IMAGES TYPES INSTALL#
Install it, and input your latitude and longitude information when prompted at setup. This is a great program that can both tell you when satellites will fly overhead and decode the audio coming into the program. If all goes well the new virtual audio device should appear in a list of input and output audio devices on your computer.ĬubicSDR, for both macOS and Windows, is a wonderful program that makes using your RTl-SDR device very easy. Install one or the other depending on your platform.
Soundflower on macOS works well for this, as does VB-Audio on Windows.
#WXTOIMG IMAGES TYPES SOFTWARE#
The first thing to install is a piece of software that enables you to pipe audio between programs. Process the audio and post-process the image.Pipe this audio into an APT decoding program.Use a tuning program to configure the RTL-SDR hardware to receive audio at 137 MHz.The basic workflow for capturing NOAA satellite data is as follows: Basically any modern computer has the processing capability for this task.
#WXTOIMG IMAGES TYPES WINDOWS#
I am writing many of the instructions below for computers running macOS, but I will also include information for Windows users. Many programs support RTL-SDR devices, so you’ll find that software programs other than the ones I link work great. The kit contains a very common device branded RTL-SDR.
