Communications Need

Space operations require extensive support from Earth, including not only a launch pad with its associated assembly and checkout equipment, but also down range guidance and command, tracking, and other communications links. After the payload is in orbit, then tracking is useful for keeping posted on it and on all other objects in space, and for commands to the payload and receipt of data gathered or observed by the payload.

The Soviet Union may have started its space program with a curious mixture of very ambitious and comprehensive plans for use of large vehicles which could perform many missions in Earth orbit and beyond, combined with minimal support on the ground in terms of varieties of hardware, limited number of pads, and minimal communications links.

It is very likely that the early launch guidance was primarily by radio, radar and optical means because of the pattern of flying down the same corridor repetitively from Tyuratam; indeed this may still be true for many space launches, simply with more radio and theodolite tracking stations being added along additional corridors. This is suggested by the fact that vehicles which almost certainly must come from different launch pads, added when new types of vehicles were added, fly on inclinations that vary from the earlier standard ones only by an amount compatible with passing near some down range tracking points in about the same relationship as vehicles launched from the original pads.

Minimal ground support will permit the start of a program, but as needs to exploit the potential of space for science and applications grow, then more is required in Earth-based facilities.
