Virtual Geo, a New Space for Broadband
The Virtual Geo satellite system involves a highly innovative orbital architecture employing satellites in highly elliptical orbits positioned and phased to reproduce the commercially significant characteristics of satellites in the geostationary arc. Satellites in the Virtual Geo formation do not interfere with satellites in the Geo arc or with terrestrial fixed services.
Virtual Geo thus allows the complete interference-free reuse of broadband spectrum, opening the way for the vastly expanded use of that spectrum for commercial and national security purposes.
A unique feature of the Virtual Geo system's orbital architecture is that the entire constellation can be controlled, and the communication path completed, from a single point on earth! Such point is preferably located on a high northern latitude such as points in Alaska. Not only efficiency is thereby enhanced, but security and quality of signal, as well (no "multiple hops").
Virtual Geo is expected an authorization from the FCC to operate, globally, across 1000 MHz down and 500 MHz up. The rules under which the licensing will take place will allow future satellite systems, under license from Ellipso, to employ the same ground-tracks with set minimum angular separation from other satellites, to allow each satellite to offer interference-free service across the entire spectrum.
Ellipso and Virtual Geo's focus now is on developing future applications. Virtual Geo's capability to deliver an unrivaled amount of capacity makes it an ideal provider to the US Department of Defense and it future transformational weapons systems. DOD officials have testified to Congress about the growing shortfall in broadband spectrum needed for operation of present and future unmanned aerial vehicles, such as the Global Hawk and the Predator, as well as unmanned ground vehicles. A comparative study of various satellite architectures, commissioned by DOD attests to Virtual Geo superior standing among many other alternatives.

Virtual Geo's access to vastly enhanced amounts of spectrum offers an array of new opportunities:
- To provide consumers with true Video On Demand with the Personal Video ChannelTM.
- To provide national defense and security systems access to global, high capacity, real-time, on demand capability for intelligence gathering and tactical needs.
- To provide capacity to aircraft for navigational purposes and for Internet services to passengers.
- To bridge into the new Internet numbering systems, known as "e-num" for universal messaging and VoIP services via the synergistic combination of Virtual Geo and E.164 capabilities.
