ST1 Satellite Transmitter IP over DVB-S2 with GigE interfaces

Ayecka ST1 is an advanced DVBS2 modulator with integrated IP Encapsulation (IPE) that provides a simple and cost-effective solution for delivering IP over satellite for point-to-point and point-to-multiple-point networks. The integrated IPE enables the support of small networks (up to 256 end points) without any additional equipment at the hub side. At the same time, the use of external IPE enables the support of unlimited network size.

Ayecka ST1’s support of advanced modulation modes at 16 and 32 APSK ST1 delivers more performance at lower cost and signifi¬cantly reduces long-term operating costs. Leading the market with its price-performance ratio, the ST1 enables new business models and revenue sources.
