Data Sources
GDP and Population TMs
Target market share is 10\% of the population
\[P = \sum_{g=1}^G population_i \times 10\%\]
Adding GDP weight ($GW_g$)
\[GW_g = P \times \frac{GDP_g}{\sum GDP_g}\]
Adding 300 Kbps data rate per head
\[T_g = GW_g \times 300 Kbps\]
Traffic demand acorss cities ($TM_{g,h}$)
\[TM_{g,h} = T_g \times \frac{1/geodesic_{g,h}}{\sum_i^G 1/geodesic_{g,i}}\]
Only Population TMs
Target market share is 10\% of the population
\[P_g = population_g \times 10\%\]
Adding 300 Kbps data rate per head
\[T_g = P_g \times 300 Kbps\]
Traffic demand acorss cities ($TM_{g,h}$)
\[TM_{g,h} = T_g \times \frac{1/geodesic_{g,h}}
{\sum_i^G 1/geodesic_{g,i}}\]
Ground Stations to Flights TMs
Ground population share and demand
\(p_g = population_g \times 10\%\)
\(T_g = p_g \times 300 Kbps\)
Flight passenger share and demand
\(p_f = population_f \times 50\%\)
\(T_f = p_f \times 300 Kbps\)
Traffic demand acorss ground and flights ($TM_{g,f}$)
\[TM_{g,f} = (T_g \times \frac{1/geo_{g,f}}{\sum_i^F 1/geo_{g,i}}) + (T_f \times \frac{1/geo_{g,f}}{\sum_i^G 1/geo_{i,f}})\]
