Table 1 Satellite configurations \(({N}_{{\rm{R}}}^{\star },{N}_{{\rm{S}}}^{\star },{h}^{\star })\), as defined in eq. (3), corresponding to the maxima of the curves for the figure of merit C(h, d) plotted in the central panel of Fig. 3.

d (km)	h^⋆ (km)	\({N}_{R}^{\star }\)	\({N}_{S}^{\star }\)	\({\overline{\eta }}_{\text{dB}}\)	\(\overline{R}\) (ebits/s)
1500	1000	7	13	62.80	1321.32
2500	1500	7	13	66.86	289.07
3500	2000	8	10	72.93	70.02

Also shown are the average loss \({\overline{\eta }}_{\text{dB}}\equiv {\overline{\eta }}_{\text{dB}}({N}_{{\rm{R}}}^{\star },{N}_{{\rm{S}}}^{\star },{h}^{\star },d)\) and average rate \(\overline{R}\equiv \overline{R}({N}_{{\rm{R}}}^{\star },{N}_{{\rm{S}}}^{\star },{h}^{\star },d)\) over 24 h for the optimal satellite configuration. See the Methods section for the formal definition of \({\overline{\eta }}_{\text{dB}}\) and \(\overline{R}\).
