Modular micro AUV communication-navigation module

The invention discloses a modular micro AUV communication-navigation module. The modular micro AUV communication-navigation module comprises an antenna module, a supporting rod, a main casing and a built-in frame, and further comprises a GPS Beidou module, a wireless communication module, a junction box, an electronic compass and an automatic pilot, wherein the antenna module is connected with the main casing in a sealing manner through the supporting rod; the antenna module is electrically connected with a first aviation plug; a second aviation plug and a third aviation plug are arranged at the two ends of the main casing respectively; the built-in frame is arranged inside the main casing; the junction box, the electronic compass and the automatic pilot are arranged on the built-in frame. The modular micro AUV communication-navigation module has the benefits that the AUV modular design structure is realized, so that a head structure can be conveniently reused, upgraded and maintained, AUV serialization and marketization application becomes possible, the structure arrangement is reasonable, and the installation space is reduced while the stability is guaranteed.
