Abstract

The paper presents the advantages of selecting a peculiar 8 hour triply geosynchronous orbit (TGO) for mobile communications. Particularly it is shown that a minimum of 6+1 TGO satellites is needed to form what is called JOCOS (juggler orbit constellation) that is able to cover the largest part of Earth land masses with elevation angle better than 20°. JOCOS is promising a significant per channel cost reduction, compared to the current geostationary alternative and can be also profitably applied to Ku/Ka band VSAT fixed services, provided that, low cost, mass production electronically steerable antennas can be developed for the traffic terminals. In summary JOCOS is a cost effective proposal for global mobile communication as well as a challenging solution to support universal personal telecommunications
