Actually, nowadays a system of ground stations and high altitudes atmospheric floating balloons can be made to serve the very same purpose. The ground stations would serve for triangulation of balloon's position and those at their turn could serve the rest of the service-consumer base. As a bonus, the balloons would be obviously more manageable compared to satellites, the cost of taking them into operation would be of course much lower (no more atmospheric pollution), and be disposed cleanly without causing the problem discussed in the article.
