Kepler Communications is a satellite communications company that is working towards establishing an in-space telecommunications network for space-borne assets. Put simply, we are building cell phone towers in space. This infrastructure will resolve the problem of intermittent connectivity for non-geostationary satellites, will open new business opportunities that necessitate real-time connectivity to satellites, and will reduce reliance on costly and difficult to deploy ground infrastructure. An infrastructure venture is no simple feat, particularly true for space-based infrastructure. To reach this long-term objective, tangible shorter-term milestones are planned in order to incrementally develop the technologies and deploy the infrastructure necessary to execute on this vision. Each milestone towards this vision represents a viable business opportunity, enabling Kepler to sustainably realize this vision.
