The downlink transfer rate for scientific and housekeeping data via the S-Band transmitter will be approx. 2.2 Mbit/sec to secure a whole data dump of 1 Gbit during a single pass at the ground station. The uplink rate for command and new software will be 19.2kbit/sec.
Both S-Band receivers are active (hot redundancy) and connected with an antenna switch to the low gain and high gain antenna.
