STM Group, the European Space Agency, and the Norwegian Space Centre are embarking on a project that will develop an integrated TDM/TDMA satellite Hub modem with very high-throughput speeds.
According to the announcement by STM, the final product will fit in a a compact 1U rack-mountable unit. The new satellite modem will enable 350 Mbps of IP throughput over DVB-S2 forward carriers and achieve symbol rates up to 200 Msps (Mega-symbols per second.) It will also support 64APSK modulation and other DVB-S2 extensions that DVB is currently standardizing.
Furthermore, the new STM modem will be able to handle burst demodulation for multiple DVB-RCS2 return carriers (maximum of 64 simultaneous unit) that are using ACM per burst to achieve an IP throughput of 150 Mbps.
An integrated Network Control Center (NCC) function will be built into the hardware platform, allowing the STM satellite modem to schedule TDMA return link bursts and track burst performance for a maximum of 10,000 active VSAT systems.
According to Helge Fanebust, Chief Technology Officer of STM, each rack unit of the new Hub modem can achieve a total throughput of 500 Mbps. This high throughput vastly exceeds the performance and density of competing satellite Hubs and will be of great benefit to VSAT networks that will use the High-Throughput Satellites. The compact Hub will also be suitable for smaller Hubs because of its smaller physical footprint and lower total cost of ownership.
A multinational satellite product and communications engineering company based in the United States and Europe, STM Group Inc. enables access to satellite broadband in central, urban, and remote regions of the world. The Company ‘s SatLink brand offers a complete selection of IP-based satellite network systems compliant with DVB-RCS & DVB-RCS2 standards and capable of operating in all frequency bands. STM products and services enable a broad range of IP based applications and see global service with consumers in the terrestrial, on-the-move, and maritime communication sectors.
