Abstract
We characterize a Borda winner in facility location problems on a sphere. We show that in desirable (undesirable) facility location problems, the center of population (the antipode of the center of population) is the unique Borda winner if the voters’ average coordinate is not equal to the center of the sphere, and that any location is a Borda winner otherwise.

Notes
Aboufadel and Austin (2006) defined the center of population as a balancing location at which the total gravitational force on population is directed toward the center of the sphere and explicitly derived the unique center of population.
Note that since \(\rho ^i\left( x\right) =\pi -\rho ^i\left( -x\right) \), a location is a maxisum (maximin) location if and only if the antipode of the location is a minisum (minimax) location.
