High-speed data rate tracking, telemetry and command (TT&C) communications with high transmission quality are required in all radio propagation conditions to check and manage the satellite status frequently and precisely. However, TT&C link speeds tend to be slow due to the use of a traditional stable S-band communication system, in contrast with mission telemetry links using X- or K- band frequency. Therefore, we have studied a new satellite communication system using adaptive modula- tion technique for medium or large satellites. The proposed system adapts symbol rates and modula- tion levels of the up-link and down-link signals accord- ing to communication channel conditions, thus improv- ing the total throughput. This paper describes the system concept, merits, feasibility, and considerations of adap- tive modulation technique as they are applied to the communication system of small satellites.
