Description

【Technical field】 [0001] The invention belongs to the field of avionics systems, in particular to an ADS-B system-level chip architecture based on a DSP core. 【Background technique】 [0002] Traditional portable ADS-B terminal systems often consist of a series of discrete devices such as central processing modules (including GNSS modules, signal processing modules, S-mode and ADS-B protocol processing modules, etc.), transmitting modules, receiving modules, and power modules. The central processing module composes the navigation information of the machine into ADS-B information and sends it to the transmitting module for external transmission, and completes the ADS-B OUT function; decodes and analyzes the ADS-B information sent by the receiving module, and converts the resolved ADS -B information and the navigation information of the machine are output to the back-end device to complete the ADS-B IN function; the power module uses a built-in rechargeable battery to provide p...
