The SkyDelta User Terminal provides broadband data, voice and video connectivity in a highly integrated cost-effective platform. SkyDelta combines the latest satellite communication technology to deliver unprecedented efficiency, performance and value.

In the forward channel, SkyDelta utilizes the new DVB-S2 standard to achieve near Shannon Limit efficiencies over a wide range of operating conditions. A DVB-RCS based, turbo code powered MF-TDMA return link delivers the highest return channel efficiency in the industry. Overall data and voice network capacity are maximized with support for both Adaptive Lossless Data Compression and VoIP header compression.








An integrated microprocessor provides critical networking functionality and high per terminal throughput. SkyDelta includes a TCP/IP accelerator, and a NAT router with Firewall, DHCP, RIP, and VoIP QoS capabilities. Network management is supported via SNMP and HTML protocols. A true multi-media platform, SkyDelta provides IGMP V2 support for multicast video.

 

 


Bandwidth Efficiency

  • DVB-S2 provides 35%+ increase in forward channel capacity / throughput relative to DVB-S (more than doubles capacity in many applications)
  • 50% reduction in terminal antennal size or required ODU RF power
  • Reduced satellite transponder requirements greatly lower network operational costs
  • Reduced RF power requirements lowers overall terminal costs & increases reliability

Compression Technology

  • ALDC provides an average of 1.5:1 compression on typical ISP-type
    traffic (increasing data throughput by 50%)
  • cRTP VoIP header compression doubles network voice capacity

Highly Integrated Design

  • Internal Router
  • Internal Power Supply supports up to 5W BUC
