How does DS1's communications system work?
No, there are actually two different transmitters. DS1 has a high gain antenna (meaning it sends a very focused beam) that will be used for essentially all communications. It also has a low gain antenna (sending a less focused stream) that broadcasts telemetry. The information from the low gain antenna will be ignored by people on Earth unless something really unusual comes up. Given that there is only one high gain antenna sending almost all the information, one interesting problem is how to allow each of the instruments and sensors time to transmit their data.
