Datum Systems specializes in satellite ground station modem design, leading the way with high performance, low cost designs for over 16 years.

The first S-TEC™ codec card was tested in the PSM-4900 Series of satellite modem over the NSS-6 satellite located at 95E and achieved exceptional results. Short term tests at Ku band have indicated no errors at 1.7 dB for rate ½ QPSK, while long term tests using a rain fade margin of 2.3 dB were error free, therefore 100% availability.

A new S-TEC™ codec card is now available for the PSM-500 Series (December 2007).

The Solante product family produced by STM Networks is a full mesh interconnected VSAT network system that uses MF-TDMA along with SCPC overlay for on demand or reconfigurable high speed data links.

The new Solante Turbo Connect with the S-TEC™ codec can be used in a variety of applications as shown in the figure on the right. The product has a built in drop and insert capability plus an IP port supporting SIP protocol. The modulation and coding rate can be configured on the fly on every on-demand link to meet the throughput requirements using the available satellite capacity.

The Satellite Network Access Point (SNAP) project at ITR represents a cost efficient turn-key solution for communications in remote communities. It targets business and individual users, covering the last mile, with the traffic aggregated in a single high data rate satellite link to an Internet backbone.

Live satellite tests over PAS8 using S-TEC™ enabled PSM-4900 satellite modems have shown that the aggregation of users in the SNAP hub can lead to significant bandwidth reduction and therefore cost savings for the satellite segment. Testing has demonstrated that SNAP represents a viable alternative to rural and remote broadband communications via satellite.
