JUPITER System Satellite Ground Network

The Hughes JUPITER™ System satellite ground network is a Very Small Aperture Terminal (VSAT) platform for broadband satellite services on both conventional and High-Throughput Satellites (HTS). The most widely used VSAT system in the world, the JUPITER platform is the system of choice for network operators, governments, mobile networks, and aeronautical and maritime service providers, operating on more than 40 satellites around the globe.

Featuring a flexible and robust gateway architecture with lights-out operation, single stream DVB-S2X wideband forward channel and enhanced Internet Protocol over Satellite (IPoS) air interface for bandwidth performance, the JUPITER System enables operators to achieve the highest possible capacity and efficiency for any satellite broadband implementation.

The JUPITER System is ideal for broadband satellite applications, ranging from home internet service to in-flight Wi-Fi.

  • Wideband DVB-S2X channels
  • Supporting more than 300 Mbps of throughput per terminal

  • Supporting acceleration of 16,000 TCP sessions per terminal - ideal for applications with many simultaneous users, such as fixed cellular backhaul and Community Wi-Fi hotspot solutions, or for mobility services on an airplane or ship

  • High density architecture: with the industry’s smallest multi-Gbps footprint, and lights-out operating mode

  • Integrated linear Ka-band radio to support both 8PSK and 16APSK higher order modulation schemes, delivering more bits per Hertz, which, combined with reduced spacing of the return channel, yields higher bandwidth efficiency and lower service cost for operators

  • Distributed or centralized gateway architecture

  • Differentiated Quality of Service for improved traffic management

  • Advanced bandwidth management

  • Advanced Internet Protocol (IP) routing features

  • Advanced HTTP acceleration

  • Advanced Encryption Standards (Link level 256 AES [optional; subject to local government approval])

  • Simple remote installation with “self-install” option

  • Network management system (NMS) with extensive virtual network operator (VNO) capabilities

  • Powerful and flexible set of Application Performance Interfaces (APIs) which can be integrated with operational support systems (OSS) and business support systems (BSS)

  • Support for mobility roaming among JUPITER-equipped operators offering aero and maritime services


Release 7.4

By design, we strive for backward compatibility in successive generations of the JUPITER System. Additionally, customers enjoy the benefits of continuous innovation with each update to the system software, the latest of which is Release 7.4. Some of the enhancements now available in JUPITER System Release 7.4 include:

  • Return Channel Adaptive Coding and Modulation (ACM) on Time Division Multiple Access (TDMA). For many years, satellite operators have enjoyed significant efficiencies through the implementation of ACM on the DVB-S2X forward channel. Now, with ACM on the TDMA return channel, operators can realize similar efficiencies – up to 30% bandwidth savings, in some cases.
  • Dynamic Return Channel Switching. Another new feature is the ability to switch return channels automatically, based on traffic characteristics, processing MF-TDMA (with ACM) and DVB-S2X transmissions.
  • New Functionality for Layer 2 Transport Support. These advances enable higher efficiency through extended implementation of acceleration of higher level protocols within the Layer 2 transport scheme


JUPITER System Evolution

The foundational technology of the JUPITER System is the powerful System on a Chip (SoC), a custom-designed VLSI processor employing a multi-core architecture. Each successive iteration of the JUPITER System technology has yielding higher throughputs and efficiencies.
