| Abstract: |
| User terminals play an important role in tracking and
data relay satellite system(TDRSS).In this paper, the classification, functions
and comp
osition of user terminal of data relay satellite system is introduced . The focu
s is placed on summary and analysis of key technologies such as all digital prog
rammable integrated baseband, automatic gain control(AGC), coherent transponding
and miniaturized technologies. The user terminal has been implemented in engine
ering, whose performance and functions meet the system requirements. Finally,the
development trend for user terminal technology is presented. |
