Problems solved by technology

[0002] On a sailing ship, the installation position of the ship’s antenna is limited, and it cannot completely avoid the obstruction. Therefore, the ship’s satellite antenna will be blocked in a certain course or on multiple courses, and the ongoing communication will be interrupted. In addition, due to the Mobile, when the position of the ship is different, the angle of the antenna shielding also changes. At present, the place where the ship can install the antenna cannot meet the shielding requirements

Embodiment Construction

[0013] The implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0014] A ship dual-antenna system based on eliminating satellite occlusion, such as figure 1 As shown, it includes the No. 1 antenna on the deck and the CDMA modem below the deck. Between the No. 1 antenna and the CDMA modem, there is a signal loop composed of the No. 1 antenna transceiver unit and the antenna control unit. It also includes the No. 1 antenna movement unit. To the antenna control circuit formed by the antenna control unit, the innovation of the present invention is that No. 2 antenna is also installed on the deck, and the No. 2 antenna is connected with the antenna control unit through the No. 2 antenna movement unit, and the No. 2 antenna transmits and receives signals through the No. 2 antenna ...

Abstract

The invention relates to a ship double-antenna system based on satellite shielding elimination. The ship double-antenna system comprises a first antenna and a CDMA modem, wherein a signal circuit and an antenna control circuit are arranged between the first antenna and the CDMA modem, the signal circuit is composed from a first antenna receiving and transmitting unit to an antenna control unit, and the antenna control circuit is composed from a first antenna movement unit to the antenna control unit. The ship double-antenna system is characterized in that a second antenna is further arranged on a deck, the second antenna is connected with the antenna control unit through a second antenna movement unit; meanwhile, the second antenna is connected with the CDMA modem through a second antenna receiving and transmitting unit, and an antenna switching unit is connected between the antenna control unit and the combination of the first antenna receiving and transmitting unit and the second antenna movement unit. According to the ship double-antenna system, the two satellite antennas are arranged in different positions and are complementary, and it is ensured that ship satellite communication is not interrupted.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, in particular to a ship dual-antenna system based on eliminating satellite occlusion. Background technique [0002] On a sailing ship, the installation position of the ship’s antenna is limited, and it cannot completely avoid the obstruction. Therefore, the ship’s satellite antenna will be blocked in a certain course or on multiple courses, and the ongoing communication will be interrupted. In addition, due to the Moving, when the position of the ship is different, the included angle of the antenna shielding also changes. At present, the places where the antenna can be installed on the ship cannot meet the shielding requirements. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, and propose a ship dual antenna system based on eliminating satellite occlusion. [0004] The present invention solves its technica...
