The invention relates a linkage-combined automatic navigation unmanned ship control system based on an APM and an I7 intelligent chip. The system comprises a ground control center and a shipborne control center, and the shipborne control center comprises a power supply subsystem, a communication subsystem, an automatic navigation subsystem, a power propulsion subsystem and a direction control subsystem; the ground control center and the shipborne control center are connected through a WIFI wireless network formed between directional and all-directional antennae in the ground control center and directional and all-directional antennae in the communication subsystem and a 2.4-G network formed among remotely-controlled modules in the direction control subsystem. According to the system, the compatibility of the APM system and the I7 intelligent chip, the operational capability of the I7 intelligent chip and the compatible capacity of a port are fully utilized, transmission, processing and storage of automatic navigation data of an unmanned ship are effectively achieved, the data storage capacity of the shipborne control center can reach 512 G, and the system can support a 8-G operation memory; the unmanned ship can complete an automatic 10-km back-and-forth navigation task on a static water surface within 1 hour.
