The paper seems to highlight that the novelty is in their general parser that worked across 39 different GEO satellites, and that it works with a couple hundred dollars of consumer grade equipment. From the paper:

"Our technical contributions include:

(1) We introduce a new method to self-align a motorized dish to improve signal quality. Specifically, we could receive IP traffic from 14.3% of all global Ku-band satellites from a single location with high signal quality and low error rate.

(2) We developed a general GEO traffic parser that can blindly decode IP packets from seven different protocol stacks that we observed in our scans. Five of these stacks have never been reported in any public research we are aware of."
