PDTX-1000 DVB-S2 Payload Data Transmitter
The PDTX-1000 Payload Data Transmitter provides a cost-effective, space-grade high-rate data downlink transmitter using a most modern modulation scheme. It offers a CAN-bus Interface for commanding and housekeeping. STT’s space equipment offers highest quality and reliability.
The PDTX-1000 is fully compliant with the CCSDS standard for payload data transmission (CCSDS 131.3-B-1), using DVB-S2. The wide-spread proliferation of DVB-S2 implementations, guaranteeing a high grade of technical maturity and offering cost-effective solutions for the ground segment.
The PDTX-1000 Payload Data Transmitter is available for operation in the C-Band (5,150 MHz to 5,216 MHz allocated on a primary basis to Space-to-Earth feeder-links of non-geostationary satellite systems for mobile-satellite services) and in the X-Band (8,025 to 8,400 MHz).
