Just released, does that mean big dipper complete space infrastructure construction, officially entered the stage of civil promotion? Industrial development has entered a stage of digital domain fusion application? List includes RNSS rf integration of baseband chip, dual-band rf baseband system more high precision integration chip, multi-mode multi-frequency broadband rf chip (global), multi-mode multi-frequency antenna (global) has high precision, multi-mode multi-frequency 5 products such as high precision modules (global), broad scope, but still with hardware integration as the core content, the application scenario description is less,
