Hi all, Interesting to see the talk about distance records.
Just for fun I tried to find the "best case" distance for the different satellites.
Conditions for the calculations: Used NOVA for Windows to find the maximum height. Used Jan Kings Spreed Sheet to find Slant Range with an elevation of 0 degrees. Multiplied by 2 to get maximum distance between two stations.
Sat. Max. Height Slant Range Max. Distance between stations
AO-51 817 km 3300 km 6600 km
SO-50 690 km 3046 km 6092 km
AO-27 800 km 3293 km 6586 km
AO-Ø7 1459 km 4552 km 9104 km
FO-29 1322 km 4314 km 8628 km
VO-52 643 km 2935 km 5870 km
SO-67 506 km 2591 km 5182 km
XW-1 1200 km 4092 km 8184 km
Hope it is right :-)
