Embodiment
[0042] Such as figure 1 structure diagram with figure 2 As shown in the functional block diagram, this embodiment provides a spatial data processing node device based on the CCSDS specification, which is realized by using the antifuse FPGA (AX2000-CG624M) of ACTEL Company, including the spatial data forward link baseband based on the CCSDS specification There are three parts: processing module 1, return link baseband processing module 2 and parameter configuration and health telemetry module 3.
[0043] Wherein, the forward link baseband processing module 1 is used to complete baseband data processing functions including data buffering, state monitoring, frame compliance detection, channel reception processing (including channel decoding, decryption, etc.) and data output .
[0044]The return link baseband processing module 2 is used to complete the return link including data buffering, channel multiplexing, data routing, packet analysis, service data priority scheduling, s...
