DDL:数据下行链路
“数据下行链路”(Data Downlink)在日常应用与专业文献中,常缩写为DDL,以简化书写与表达,提高工作效率。这一术语在美国国家航空航天局(NASA)等航天机构中尤为常见,专指将航天器采集的数据传输至地面接收站的关键技术环节。
Data DownLink具体释义
Data DownLink的英文发音
例句
- And then the characteristics of the radio propagation in ionosphere are analyzed and the impacts on X band propagation link caused by ionized layer are estimated, and the results show that the ionized layer does not disturb the data downlink each other.
- 分析了电离层电波传播特性,并估算了电离层对X波段传播链路的影响,得出数据下传过程与电离层之间不会相互干扰的结论。
- High Speed Data Downlink of Airborne SAR in the Pilotless Aircraft
- 无人机机载合成孔径雷达的高速数据传输
- In this transmission link with many hops, there are the uplink monitoring data and downlink control, management data, distribution tasks of the system at the same time.
- 在此多跳传输链路中同时有上行的感知数据和下行的系统控制、管理、分配监测任务等数据。
- In the mean time, the conflict between the large data rate of the raw data and downlink speed is becoming more and more obvious.
- 与此同时,SAR系统庞大的数据量和下传速度之间的矛盾也日益明显,SAR原始数据压缩技术是缓解这一矛盾的一种有效手段。
- When a GPRS MS in READY state uses DRX, DRX has to be considered when assigning a packet data channel for downlink transfer.
- 当一个READY状态的MS使用了DRX,DRX将在为下行数据传递分配数据包信道的时候被考虑进去。
