To work amateur satellites you need an antenna that can track the path of the object as it crosses the sky. This means that you must be able to rotate the antenna around as well as up and down. To obtain the tracks and the footprint, the area on earth that can use the satellite, use the links below.
The amateur satellites are coordinated by the AMSAT group who assign them numbers when they become operational, such as Oscar 10.
