Satellite Ground Systems Market

What makes HTS so attractive is its high level of frequency re-use and spot beams enabling, for example, a gigabyte or more of frequency to be re-purposed by 50 times or more.  EuroConsult estimates that approximately 130 HTS satellites will be launched in the next eight years.  Each HTS satellite requires at least 1 gateway for each time the frequency is reused. As a result, thousands of new gateways will be required to support all of this new bandwidth. This requirement will put significant operational, financial and quality of service strains on operators unless they are able to revolutionize the fundamentals of satellite ground system architecture.

A typical gateway costs roughly $2 million to $4 million each, depending on the system requirements.  Therefore, considering that lighting up a single HTS could require up to 10 gateways in the first few years of operations results in a $20-$40 million investment.   Can the innovation that is enabling HTS in the sky be met with a new wave of innovation to optimize ground system performance and economics?  

To enhance gateway optimization the industry will require

  • Dramatic changes to gateway design and management
  • New levels of flexibility in placement and architecture decisions
  • Capabilities to manage across RF and IP operations for better margins and service quality
  • Reduced antenna costs and accelerated delivery times
  • Virtualized infrastructure
  • …all of which will significantly reduce CapEx and OpEx while enhancing performance

This presentation will address some of the new technologies and approaches being taken to re-architecture satellite ground system design to more readily enable and fulfill the promise of HTS satellites.
