Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution of the present invention will be further described below in conjunction with specific examples.

[0024] A method for realizing microwave directional communication at sea based on the Beidou system, comprising the following steps:

[0025] Step 1: The ship must be equipped with the Beidou satellite navigation system (hereinafter referred to as the Beidou system) and the microwave system, and each ship sends its position back to the land Beidou data center (this process is achieved through the Beidou satellite).

[0026] Step 2: Ship A uses the short message function of the Beidou system to send a link request to the Beidou ground data center in a specific message format.

[0027] Step 3: After receiving the link request from ship A, the Beidou ground data center finds out other ships within 150KM of ship A according to the real-time position of...

Abstract

The invention discloses a method for realizing microwave directional communication at sea based on the Beidou system. The ship is equipped with the Beidou system and the microwave system, and each ship transmits its position back to the land Beidou data center at regular intervals through the Beidou system; the ship A uses the Beidou system The short message function sends a link request to the Beidou ground data center; the Beidou ground data center finds out other ships within the directional microwave communication range of ship A, and sends the position information of these ships to the Beidou system of ship A; ship A chooses to The target ship B for communication, and adjust the antenna so that the antenna points to ship B. Ship A sends the request for linking ship B and its own position information to the Beidou ground data center through the Beidou system, and the Beidou ground data center will forward the information to the ship. B; ship B adjusts the antenna so that the antenna points to ship A, and ship A and ship B are linked through the microwave system for real-time transmission of directional microwave signals.

Description

technical field [0001] The invention belongs to the technical field of maritime communication, and in particular relates to a method for realizing microwave directional communication at sea based on the Beidou system. Background technique [0002] The unique short message communication function of Beidou satellite navigation system will support the development of various new services. The application technology of directional and omnidirectional microwave systems on land is very mature. Due to the particularity of ships and the ocean, the application of microwave systems in the field of marine communication is still in a blank stage. The combination of Beidou system and microwave system makes remote automatic tracking of microwave antennas became possible. [0003] The types and characteristics of microwave are shown in the table below: [0004] [0005] Table 1 [0006] It can be seen that the transmission distance of the omnidirectional microwave and the fan-shaped m...
