I was impressed as I usually needed to wait for the satellite to be high enough but this time I could get a signal even before the app is telling me that the Satellite is at the horizon and I could still get it after it has disappeared from the app.Īs the computer was recording and displaying the raw image in real time, I walked around and enjoyed the view from the top of the cliff.Īnd here are the final result.
It shows the satellite and its trajectory in real time and with the iPhone's compass it's easy to track the satellites.įor a better signal, I could hand hold the antenna and point it at the satellite but NOAA satellites' trajectory are always North-South so a 120 degree V-Dipole antenna pointing North or South is enough to receive a clear signal even when the satellite is low on the horizon. I'm using the Orbit a free iPhone app for tracking satellites.

I then connected the antenna to a RTL-SDR v3 USB dongle itself connected to a Macbook Pro running CubicSDR for receiving the radio signal and Wxtoimg for decoding it and generating the weather image. From memory, each of the antenna element is at about 16.51 cm forming a V shape at 120 degrees pointing South and the radio is tuned at 137.9125 MHz. It's approximately 100-150m high and it's wide open all around which is great for capturing radio signals where line of sight is important.Īfter I got up there, I first setup my antenna for NOAA imagery. Today, I decided to drive to Terrigal "The Skillion", about 30 minutes from home. My other option to get a strong signal is to climb on the roof of the house but as I'm surrounded with mountains and trees, I need to wait until the satellite is at a certain height above the horizon before I could get something. When at home, I can receive some signal from NOAA 15, 18 and 19 indoor but it would be rather weak, unless the satellites are passing high overhead.

Due software limitation on Mac OS X, I'm currently focusing on NOAA weather satellite imagery and ADS-B (air traffic surveillance). I recently started to play with my SDR (Software Defined Radio) trying to receive any radio signal I could reach and decoding them.
