Antique element sets
Here I have listed Two-Line Element sets for some early space missions.
This format is recognized by most orbit plotting programs. With a few exceptions
I have produced them myself using various sources of orbital data. I have
also tried to correlate some of the elemnt sets with radio and visual observations.
This information is for the real "aficionado" who wants to check radio
or visual observations of these missions. I plan to include more early
The element sets should be accurate (I hope ) for the early phases of
the missions. (The checksum is not correct, BTW. It is just a "dummy" character).
