| Abstract: |
| A bi-channel remote sensing satellite data acquiring and playing back sydtem was realized using lai^e scale programmable logic devices and high speed, memory devices based on PCI bus technique, and the practical remote sensing satellite data real-time acquiring testing and the ajcquiring testing on remote sensing satellite data produced by a simulator were implemented respectively. The testing results show that this system can receive most of the remote sensing satellite downlink data, and ihe maximum inputting frequency can be up to 640 Mbil/s, hence the problems on data acquiring, ay^tem debugging and data source development in remote sensing satellite ground recording system are resolved effectively. In contrast to the existing recoding system，this system has simple structure with lower cost，and the function of satellite simulator makes up the defect of existing recording system. |
