This invention provides an onboard real-time processing and broadcast distribution system and method. The method includes the following steps: S1: receiving probe data from the payload using an onboard real-time processor and generating product information; S2: sending the generated product information to a broadcast distribution terminal; S3: processing the product information in the broadcast distribution terminal; S4: performing a gating operation on the shaped and filtered L-band modulated signal to connect it to a solid-state amplifier; S5: amplifying the modulated signal and transmitting it to an L-band broadcast antenna; and S6: broadcasting the product information to ground users through the L-band broadcast antenna. This invention can meet users' needs for timely acquisition of satellite probe information products; the wide coverage of the broadcast distribution can meet the needs of all users within the satellite orbital arc for obtaining product information; and the system reliability is improved by implementing a single-unit cross-backup design scheme through an L-band microwave switch.
