How does DS1's communications system work?

What is the Small Deep Space Transponder?

The small deep space transponder combines the many separate functions that other spacecraft telecommunications systems perform into one unit. This unit has less than half the mass than would be required without this new technology. It contains several innovations that will help it meet the needs of many future missions.

The small deep space transponder has the ability to generate the beacon signals in Beacon Monitor Operations. Space projects that use the transponder will be saved the burden of designing their own telecommunications systems, and will be able to take advantage of the transponder's modern components and design techniques to save mass. The transponder has built into it the ability to use the new Ka-band radio frequency which will improve the efficiency of DSN communications.
