HX System TGW100

Resource Type
Data Sheet

The HX TGW100 is suited for applications where network transportability is critical—including homeland security, continuity of operations, tactical military, and remote news gathering. Standing just 24” in height, the HX TGW100 is a size- and cost-efficient solution to support the rapid deployment of smaller satellite networks in difficult operating conditions.

Based on the same architecture as the larger, fully-redundant HX System gateway, the HX TGW100 provides unsurpassed flexibility and scalability in a small, powerful package. It comes in a compact eight rack unit (RU) transit case optimized for rapid network deployment. With the addition of an expansion pod, the HX TGW100 can easily be scaled to support the entire suite of HX System services for larger networks. Personnel trained to operate the HX TGW100 are also able to operate larger-scaled HX regional hubs because of the common product architecture and network management system, the HX ExpertNMSTM.

HX TGW100 Architecture

The HX TGW100 architecture is highly modular and scalable, and enables rapid deployment and provisioning of HX System services from a single comprehensive platform. Fully compliant with DVB-S2/IPoS, the world’s leading satellite transmission standard and including Adaptive Coding and Modulation (ACM), bandwidth efficiency and flexibility are at the core of the HX TGW100 design. For example, one or more terminals can be selected for guaranteed inroute bandwidth, while the remaining terminals share fair access via a truly dynamic bandwidth assignment algorithm. The HX TGW100 supports outbound data rates of up to 121 Mbps and inbound data rates of up to 9.6 Mbps.

HX TGW100 Features

  • Supports star and star/mesh configurations

  • SATCOM on-the-move (mobile terminal) operation


The DVB-S2/IPoS with ACM Advantages

The HX TGW100 is fully compliant with the global IPoS standard, the world’s first standard to be approved by the TIA, ETSI, and ITU standards organizations, and which incorporates the DVB-S2 standard. The Hughes implementation includes ACM, which yields up to 50 percent more efficient bandwidth utilization and higher throughputs than the DVB-S specification. DVB-S2/IPoS with ACM advantages include:

  • Clearly defined interface conforms to the ETSI SI-SAP standard enabling back-end systems to work easily with the HX infrastructure
  • Optimum transmission efficiency through a combination of coding and modulation of the outbound channel that can be configured for each remote terminal
  • Continually optimized link performance (even during high rain conditions) by dynamic adjustment of error-correcting codes and modulation based on signal quality feedback from remote terminals
  • Truly dynamic bandwidth assignment—remote sites with no traffic are assigned no resources
  • Multiple inroute quality of service options—Committed Information Rates (CIRs) per active remote terminal or group of terminals


The HX System from Hughes, the world leader in broadband satellite networks and services, is designed and optimized for smaller and mobile networks, including maritime and airborne applications, where the provision of high-quality and high-bandwidth links is paramount. Capable of simultaneous mesh, star, and multi-star configurations, the HX System builds upon the capabilities and global success of the high-performance HN System, incorporating many advanced features pioneered by Hughes, including integrated TCP acceleration and advanced IP networking. Its broadband satellite products are based on global standards approved by TIA, ETSI, and ITU, including IPoS/DVB-S2, RSM-A, and GMR-1. To date, Hughes has shipped more than 3.3 million satellite terminals to customers in over 100 countries.
