Different types of business, it is necessary to carry out artificially dividing to can be only achieved in different data transfers not interfereing with each other to channel, do not account for mutually
With；On the other hand, the increased Error Correction of Coding of corrupt data institute in order to prevent, further reduce channel bandwidth utilization ratio.3
In the presence of the design and development of repeatability：Due to spacecraft platform do not possess standardization, no matter platform interface is from hardware, software
The test of links in inheritance design or manufacture flow, there are more repeatability design and development work, makes
Into the waste of human and material resources cost and the increase of lead time.It can be drawn by above-mentioned analysis：According to the existing spacecraft in China
Platform, satellite platform, payload platform data bus interface feature, with reference to domestic and international correlation technique development trend, development can be real
Existing compatible existing bus interface, and realize that the multiplexing of the multiple interfaces such as remote measuring and controlling, load data, the high speed fibre of channel multiplexing connect
Mouth chip is necessary.
