Abstract

The invention discloses a ship-machine time / inertial navigation wireless initial alignment system, comprising a wireless distribution device, a process monitoring device, an ultra-short wave antenna and a channel, and a plurality of wireless alignment handheld terminals. The distribution device communicates with a plurality of wireless aiming handheld terminals through the ultra-short wave antenna and channel; wherein, the wireless distribution device receives the ship's inertial navigation information through the shipboard network, converts the information through the ultra-short wave antenna, and uses the authorized ultra-short wave channel. The carrier-borne inertial navigation information is wirelessly transmitted to the wireless alignment handheld terminal by wireless broadcasting, and the wireless alignment handheld terminal is connected to the carrier-based aircraft through a short cable to realize the initial alignment of the carrier-based aircraft. The invention also discloses a ship-machine time / inertial navigation wireless initial alignment method. The invention can eliminate the hidden danger that the flight deck cable interferes with the take-off and landing of the aircraft, and improves the dispatch rate of the aircraft, thereby improving the combat effectiveness of the ship.

Description

technical field [0001] The invention relates to an alignment system and an alignment method, in particular to a ship-machine time / inertial navigation wireless initial alignment system and an alignment method. Background technique [0002] Ship-aircraft alignment refers to the process of initial alignment of the aircraft's airborne inertial navigation and airborne information equipment with the mothership's shipboard inertial navigation information and shipboard time system information before take-off during the ship's navigation. [0003] At present, the mothership usually drags the main inertial navigation information and time information in the cabin to the aircraft on the deck through multiple long cables to achieve initial alignment with multiple aircraft. This method needs to drag multiple long cables on the flight deck. Due to the limitation of cable layout, the aircraft needs to be aligned at a fixed location, which seriously affects the dispatch rate of the aircraft....
