| 摘 要： | 针对中低轨航天器监控全时全域覆盖的特点，提出一种采用中继卫星多址返向全景波束联合相扫前向波束支持航天器在轨全时监控的模式。对该模式涉及的全景波束技术进行了仿真分析比较。结果表明，选用数字波束形成技术和1.5 dB交叠的波束构型形成全景波束，设计新的短报文和连续业务数据传输协议，分别用于航天器自身健康信息汇报和常规管控，链路预算余量高于3 dB，单颗中继卫星可服务不少于1000个短报文用户。为下一步全景波束演示验证试验和工程应用提供了参考依据。

| Abstract: | Based on the requirement of spacecraft on orbit
control at anytime and anywhere, a control mode using tracking and data relay
satellite (TDRS) S band multiple access (SMA) is designed
in this paper. And digital beam forming (DBF) technologies, all sighted beam covering and communications protocols are researched.
The results show that the all sighted beam system
formed by overlapping 1.5 dB is reasonable, communications protocols of short
messages and continuous services can meet the demands of data transmission, all
the link budget margins exceed 3 dB, and one TDRS can provide short message
services for all of 1000 users. It is highly possible in actual to control LEO
and MEO spacecraft at anytime and anywhere by TDRS SMA. |
