I am on the East Coast of the US about 4 miles from the ocean. Wallops Island is north of my location. This morning NASA launched and Athena rocket with supplies to go to the ISS. Rather than sit in the shed, I went to the beach to watch for the rocket (which was pretty cool to see). My question is do rockets, particularly NASA launches, have transponders that I could track on my setup at home, which feeds PlaneFinder?
