Weather was accommodating and we maintained the proper 6 foot social distance for COVID-19 compliance, as we really needed to capture the measurements for our research paper on jamming the satellite receiving dish/node, while connected and receiving blockstream data from Galaxy 18. Measurements took some time, but we were successful in testing the jamming as well as capturing the measurement readings at various approaches (phi) and distances between the receiving satellite dish and the mobile jammer. Measurements were taken directly in front of the dish/LNB, as well as from the sides of the dish and behind the dish. It was interesting to see how the jammer affected the receiving satellite dish's analog and digital signal reception. There were some interesting observations and findings from our efforts today, and once we have time to more deeply review and analyze the measurements captured in our log files, we will be able to make some good insights into our resulting paper!

After much trial and learning the art of tuning a small satellite dish (90 cm) to a geo stationary satellite in orbit (specifically Galaxy 18), I was finally able to successfully link my Ubuntu desktop running the blockstream receiver with the blockstream transponder on Galaxy 18! This is my first experience and had to acquire both the working knowledge of the how to fine tune to a specific satellite, as well as acquire the necessary tools to help simplify the overall frustrating process.
A small victory, but a great feeling to see the data frames being received with no modulation errors in the blockstream receiver!
Here are some pictures of the equipment and tools I used:

Welcome to my research blog!
Now that I'm finishing up my required courses for my PhD at the University of Colorado, Colorado Springs (UCCS), I'll need to start researching more towards my dissertation and publication of at least one paper in a Tier 1 or 2 venue. Currently focused on leveraging my expertise with software defined radio (SDR) to investigate radio transmissions and push the state of the art in either vehicular security or satellite communications security.
