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 embodiments.

[0024] A method for implementing maritime microwave directional communication based on the Beidou system includes the following steps:

[0025] Step 1. Ships need to be equipped with Beidou satellite navigation system (hereinafter referred to as Beidou system) and microwave system. Each ship transmits its position to the land Beidou data center at regular intervals (preferably refresh interval ≤10 minutes) through the Beidou system (this process is 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 the Beidou ground data center receives the link request of ship A, it finds out other ships wi...

Abstract

The invention discloses a method for realizing maritime microwave directional communication based on a Beidou system. The method comprises the steps of configuring the Beidou system and a microwave system on a ship, and enabling each ship to transmit the respective position back to a land Beidou data center at regular time through the Beidou system; enabling the ship A to send a link request to the Beidou ground data center by using a short message function of the Beidou system; enabling the Beidou ground data center to find out other ships within the directional microwave communication rangeof the ship A and send the position information of the ships to the Beidou system of the ship A; enabling the ship A to select a target ship B to be communicated, adjusting an antenna to point to theship B, enabling the ship A to send a request for linking the ship B and position information of the ship A to the Beidou ground data center through the Beidou system, and enabling the Beidou ground data center to forward the information to the ship B; and enabling the ship B to adjust the antenna to enable the antenna to point to the ship A, and linking the ship A and the ship B through a microwave system to perform directional microwave signal real-time transmission.

Description

Technical field [0001] The invention belongs to the technical field of maritime communication, and specifically relates to a method for realizing maritime microwave directional communication 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 at 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 microwaves are shown in the following table: [0004] [0005] Table 1 [0006] It can be seen that the transmission distance of omnidirectional microwave and fan-shaped microwave is rela...
