Use a tracking program to help explain this. The altitude/height for SO-59
varies between 615-704 km above the earth because of the orbit. The range
depends upon the maximum elevation that the satellite reaches on each pass.
At the beginning of a pass for SO-50 the range is around 3000km and for each
pass the range will decrease until it is at TCA. The range at a 90 degree
pass over a QTH will be the same as the altitude.
The signal will have quite a bit of path loss difference due to the large
(3000 to 700 km) distances experienced during a pass. Generally the
beginning and ending signal will be around 3000km and the signal at TCA
depends upon the maximum elevation for that pass.
