ADS-B chip architecture based on special integrated circuit

Abstract

The invention discloses an ADS-B chip based on a special integrated circuit. The ADS-B chip based on the special integrated circuit comprises an ADC module, a DAC module, a 1090 ES interface module, asignal coding and decoding module, a CPR and data coding and decoding module and a data flow control module which are connected to a high-speed bus; the data flow control module controls the 1090 ESinterface module, the signal coding and decoding module and the CPR and data coding and decoding module; and the 1090 ES interface module controls the ADC module and the DAC module. Discrete hardwaremodules including a logic control module, a signal processing module, an ADS-B protocol processing module, a memory module, an ADC / DAC front end module, a power providing and power consumption management module, an external interface module and the like and a software algorithm in ADS-B system equipment are solidified in a special integrated circuit ASIC chip which has an ADS-B and ADS-B IN functions, and thus, microminiature and low power consumption of the ADS-B system equipment are realized.

Description

technical field [0001] The invention relates to an integrated circuit technology in the field of aviation technology, in particular to an application-specific integrated circuit (ASIC) for realizing the ADS-B function. 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 powe...

Problems solved by technology

Although the miniaturization of the ADS-B system can be achieved through compact structure layout and appropriate integrated circuit synthesis technology, the effect of this method is limited. Even if the cost factor is not considered, it is completely dependent on high-performance small package components. It is also unable to meet the installation requirements of general aviation aircraft, especially the rapid development of unmanned aerial vehicles.
