S-band transceivers
Searching for a CCSDS-compatible S-band transceivers.
Uplink shall comply to CCSDS 231.0-B-4 & 232.0-B-4. For channel coding, only BCH coding is required. BCH may operate in checksum mode (ie: SECDED mode is not required). If part of the framing layer needs to be implemented on the customer side, that is acceptable, as long as the unit at minimum extracts transfer frames. Uplink data rate up to 100 kbps.
Downlink shall comply to CCSDS 131.0-B-6 & 132.0-B-3. For channel coding, 1/2 rate convolutional coding + RS(255,233) w/interleaving is required. If part of the framing layer needs to be implemented on the customer side, that is acceptable, as long as the unit can consume transfer frames. Downlink data rate up to 1 Mbps.
TID hardening is not required, but the system shall be resilient to SEEs (ie: SEU, SEL) up to 600 km.
Looking to procure 5 EMs & 5 FMs. If the unit operates satisfactorily, this may lead to a long-term engagement of 5-10 FMs/year starting in 2030.
