The RTL SDR dongle combined with a good antenna, SDRSharp and a decoding program can be used to download and display these live images several times a day. This tutorial will show you how to set up a NOAA weather satellite receiving station, which will allow you to gather several live weather satellite images each day. Most parts of this tutorial are also applicable to other software radios, such as the Funcube dongle and Hack. RF and Airspy, but the RTL SDR is the cheapest option. Hardware radio scanners can also work, provided the radio has a large IF bandwidth 3. Hz and a discriminator tap. Note that if you have success with this tutorial, you may also be interested in decoding Meteor M N2 weather satellites which provide much higher resolution images. Also, an alternative tutorial for decoding NOAA satellites that uses rtlfm can be found here. Examples. You. Tube user Gait. Uut. Liern shows an example of receiving NOAA satellite weather images with a RTL SDR, SDRSharp, a decoding program called WXto. Img and a QFH antenna. Here, You. Tube user themrworf. He used a RTL SDR with SDRSharp, WXto. ElgYo-rBq8/hqdefault.jpg' alt='Control M Scheduler Tutorial Pdf' title='Control M Scheduler Tutorial Pdf' />Img, a QFH antenna and also an LNA. Requirements and Setup. To set up a NOAA weather satellite receive station you will need An RTL SDR dongle working with SDRSharp. Or other more advanced SDRs such an AirspyAn audio piping method. A right hand circularly polarized antenna tuned to 1. MHz. Software such as WXto. Img for decoding the APT signal. An LNA Optional. We will assume you have the RTL SDR dongle set up and working already. If you have not bought a dongle yet, see the Buy RTL SDR page for information and the check out the Quickstart Guide for an easy setup routine with SDRSharp. You will also need to have an audio piping method installed and set up. Audio piping will allow the audio from SDRSharp to be passed to a decoding program. You can use either windows stereo mix, VB cable free or virtual audio cable paid with trial version. NOAA Weather Satellite Antennas. The NOAA APT weather satellites broadcast their signal at about 1. MHz, and their signals are also right hand circularly polarized RHCP, which means you will need a right hand circularly polarized antenna to properly receive the signals. Satellite antennas are also designed to receive best from signals coming from the sky. Three options for easy home made circularly polarized satellite antennas are presented below. Turnstile Antenna. A turnstile antenna is a circularly polarized antenna. It can be built in two modes, normal and axial. For satellite reception we want it in axial mode. A page showing a turnstile antenna for 1. MHz is here. Quadrifilar Helix QFH Antenna. A Quadrifilar Helix QFH is a circularly polarized antenna that can be constructed out of PVC pipe and coax cable. Most people report that the QFH antenna has slightly superior reception compared to the turnstile. If you are into antenna theory, a good technical paper on the QFH called QHA in the paper can be found here. A tutorial on building a QFH out of coax cable and PVC pipe can be found here. Another home brew QFH antenna constructed out of copper wire is here. Also, a good calculator for determining QFH antenna dimensions for 1. MHz can be found here. V Dipole. Recently it was discovered by 9. A4. QV Adam that a simple dipole arranged into a Vee shape placed horizontally makes an excellent and extremely simple weather satellite antenna. This is probably the easiest beginners antenna to build as it only consists of two wires and some coaxial cable. More details about this antenna can be found on this post. In addition from this others have been using simple TV bunny ear antennas for the same purpose, for example see this post. Double Cross Antenna DCAAnother antenna that works well with the NOAA APT satellites is the double cross antenna DCA. It is basically four dipoles arranged in a certain way to produce circular polarization. A good guide on DCA antennas, and constructing them can be found in this pdf guide by Gerald Martes KD6. JDJ. Yagi antennas can also work, but since they are so directional you will need to carefully track the satellite by hand, or by using a rotor controller. Although not designed for satellite reception, you may also see limited success with other antennas such as quarter wave ground planes and discones, but you will probably discover that the signal will fade in and out. Software Tutorial. The NOAA satellites only pass overhead at certain times of the day, broadcasting a signal. These signals appear at around 1. MHz, and only when a satellite is passing overhead. Each satellite has a different frequency. Currently only NOAA satellites 1. NOAA 1. 5  1. 37. MHz. NOAA 1. 8  1. MHz. NOAA 1. 9  1. MHz. An example of a NOAA APT weather satellite signal is shown zoomed in and out on the frequency spectrum directly below and an example audio file of the signal is shown further below. APT Signal Zoomed in. APT Signal Zoomed Outhttps www. NOAAAPT. mp. 3WXto. Img Tutorial. WXto. Img is a free weather satellite decoding program which can decode the APT signal, and also tell you the times and frequencies of the NOAA satellites passing overhead. There is also a paid version of WXto. Img which can unlock more features, however it is not required for use with RTL SDR. To use WXto. Img and SDRSharp together follow the instructions below. First, download and install WXto. Img from their homepage here. Next open WXto. Img, and then set your Ground Station Location, which is the coordinates of your antenna by going to Options Ground Station Location. The city you are in should suffice, but you can be more accurate by entering in an exact latitude and longitude if you want. In WXto. Img set your audio piping method which you have chosen. To do this go to Options Recording Options, and ensure the correct device is selected under the soundcard option. Also, here you can adjust the Record only when active APT satellites are overhead with maximum elevation above degrees and record only when satellite is above degrees settings. Active Life Physical Therapy Hayward. You may want to reduce the default values if you have an antenna with a good view of the sky and find that WXto. Img stops recording or doesnt start fast enough even though the APT signal is present in SDRSharp. Now you will need to update your Kepler files. These files contain the information about satellite locations. They need to be periodically updated, because satellites drift in their orbit over time. Go to File Update Keplers to do this. Make sure you have an internet connection for the update. Now you can go to File Satellite Pass List, and find a time when a satellite will be passing overhead. Take note of the frequency as well. When the time comes for the satellite to appear, open WXto. Img, and then go to File Record, and click on Auto Record. The recording and decoding will begin when the satellite appears on your horizon, and stop when it goes out of view according to the times in the satellite pass list. Open SDRSharp select the audio piping method you are using under the Audio Output drop down box and then tune to the frequency that the satellite will be broadcasting at.
