Telecommunications Description

The downlink frequency to NASA's Deep Space Network is 2273.000 MHz and the uplink frequency is 2093.0541 MHz. Both frequencies are S-band. Data are downlinked at 1800 bps as they are collected and also stored on a solid-state recorder for downlink 53 minutes later at 1800 bps, so no data is lost during blackout periods. The real-time and delayed downlink data are interleaved for a total downlink data rate of 3600 bps. Engineering-only data is downlinked at 300 bps. There is no on-board computer control, all spacecraft commanding is done from a ground computer via the S-band uplink.
