1. A method for auto-scaling satellite receiver characteristics wherein the method is incorporated into a satellite system analysis computer program for design selection comprising: (a) defining first transmitter characterstics; (b) automatically defining first receiver characteristics based upon the first transmitter characteristics; (c) defining the communications link between the first transmitter and first receiver; (d) generating first communication link performance data; (e) determining acceptability of the first communications link performance; (f) creating second transmitter characteristics when first communication link performance is unacceptable; (g) automatically creating second receiver characteristics based upon the second transmitter and second receiver characteistics; (h) generating second communications link performance data based upon the second transmitter and second receiver characteristics; (i) determining acceptability of the second communications link performance; and (j) accepting the revised transmitter add revised receiver characteristics when link performance data is acceptable.
