TDRS-L
A tracking and relay satellite.
www.nasa.gov...
The third generation TDRS will be functionally identical to the second generation TDRS with one major exception – beamforming. Multiple Access beamforming will be performed on the ground, unlike the second generation spacecraft which performs this function on-board. Like the first generation, this will allow for the unscheduled S-band DAS to be possible for low data rate use.
