You will need to change your stations GPS coordinates in the following filesĮdit the file noaa_sat_schedule.sh and change the following details to your coordinates. (the index.php will need to be moved later) Inside the directory there will be three scripts. It will create a directory noaa_weather in the sh directory
#Wxtoimg raspberry pi install
sudo apt-get install predictĬreate a directory sh in hour home directory.Ĭreate a wxsat directory in your home directoryĬreate a images directory in wxsat directoryĬreate a thumb directory inside the images directory.Ĭd to sh directory and download the following scripts from github using the git command below
#Wxtoimg raspberry pi software
The following software need to be installed on Raspberry Pi or Linux server. Apache server to expose the images to the internet.wxtoimg - Utility that converts ATP Audio files into Satellite Images.Shell script to calculate the schedule for enabling the rtl receiver.Sox - To convert row Audio file into format for wxtoimg to convert to Satellite Image.rtl_fm - SDR fm Demodulation Utility to decode your ATP Satellite signal to audio file.
Predict - Utility to calculate satellite azimuth and elevation using TLE Kep elements.All Hardware and software is available from Giga Technology.RG58 Coaxial cable with connectors or better cable.RTL dongle with USB cable and MCX connector adaptor.The images is then exposed via a Apache web server with a php plugin to the internet.The converted recordings is then passed to wxtoimg utility to generate the Satellite images.The Audio files is not in the correct format for wxtoimg utility to convert it to images and need to be converted to the correct format using the SOX until.The " at" scheduler will then start and stop the rtl_fm receiver at the required time, frequency and record the audio in the recording directory from the NOAA satellite.The result of the calculations for the next 24 hours is then send to a scheduler program call " at".The predict software calculate when the next satellite will be above your radio station.The NOAA satellite TLE data is then passed to the predict satellite positioning software.The shell scrip will fetch the satellite TLE keps data from celestrack.The system consists of 3 shell scripts that tai 5 applications together.Here is a Link to Automated NOAA weather satellite System In Bassonia South Africa. What do you need to setup a automatic NOAA APT Weather station configuration. Receiving NOAA weather satellite images with a RTL dongle and a Turnstile crossed dipole automatically.
