Iridium and GPS (Global Positioning System) combined antenna for underwater robot

Abstract

The invention relates to a combined antenna, in particular to an iridium and GPS (Global Positioning System) combined antenna for an underwater robot. The iridium and GPS combined antenna comprises an antenna adapter component, a fixed base, a connecting pipe and an antenna assembly which are sequentially and hermetically connected, wherein the antenna adapter component comprises a watertight cable, a setting framework, a connector locating ring and a coaxial connector; the setting framework is hermetically connected with the fixed base; one end of the setting framework is provided with the connector locating ring; the coaxial connector is inserted into the connector locating ring, and one end of the coaxial connector is connected with the watertight cable; the watertight cable is hermetically connected with the setting framework; the antenna assembly comprises an antenna housing fixing piece, an iridium antenna, a GPS antenna and an antenna housing; one end of the antenna housing fixing piece is in hermetical and threaded connection with the connecting pipe, and the other end of the antenna housing fixing piece is hermetically connected with the antenna housing; the iridium antenna and the GPS antenna are both encapsulated in the antenna housing and are respectively connected with the other end of the coaxial connector by virtue of a coaxial signal wire. The iridium and GPS combined antenna has the advantages of simple structure, good underwater sealing property and antenna signals, easiness for installation and the like.

Description

technical field [0001] The invention relates to a combined antenna, in particular to an iridium and GPS combined antenna for an underwater robot. Background technique [0002] An underwater robot is a movable underwater device that can perform specific tasks underwater. Underwater robots can generally be divided into cabled underwater vehicles (ROV) and untethered underwater autonomous vehicles (AUV). The communication and positioning of the cabled underwater robot are generally directly connected to the operating platform and the robot through the cable or optical fiber, and the ROV can be controlled in real time through the operating platform, but the length of the cable or optical fiber limits the range of activities of the ROV; There is no physical connection between the console of the autonomous robot (AUV) and the robot, so it has the characteristics of wide cruising range and long range, but its communication and positioning are relatively complicated.

Problems solved by technology

[0004] At present, the types of antennas used on land in China are very complete, but most of the antennas dedicated to underwater need to rely on imports. The import cost is very expensive, and the structure is complicated, which is not conducive to maintenance.
