摘要: |
针对测试过程中,低轨卫星下行数据种类繁多、信息量大,在测试中,数据判读人员常常只能监视其中某一通道的数据,其他通道数据的正确性只能在测试之后,人工进行比对判读,工作量大、效率低,采取面向低轨卫星的多通道数据实时比对方法,能够帮助测试人员在测试中实时对多通道数据的一致性进行比对,提升测试效率。 |

Abstract: |
Downlink data for low-orbit satellite are large and varied. In the test, the data interpreter often can only monitor one of the channels of data,while the correctness of other channels of data can only be compared manually after the test, which is heavy in workload and low efficiency. In this paper, a real-time comparison method is studied and implemented for low-orbit satellite multi-channel data. It can help testers to compare the consistency of multiple channel data in real time and improve the efficiency of the test. |
