Abstract

The invention discloses a wireless initial alignment system and an alignment method for the time / inertial navigation of ships and aircrafts, comprising a wireless distribution device, a process monitoring device, an ultrashort wave antenna and channels, and multiple wirelessly aligned handheld terminals. The wireless distribution device is connected to the process monitoring device. The wireless distribution device communicates with the multiple wirelessly aligned handheld terminals through the ultrashort wave antenna and the channels. The wireless distribution device receives the ship inertial navigation information through the shipborne network, converts the information through the ultrashort wave antenna, using the ultrashort wave channel which has been authorized, and transmits the shipborne inertial navigation information to the wirelessly aligned handheld terminals by wireless broadcasting. The wirelessly aligned handheld terminals are connected to the shipborne aircrafts via short cables to achieve initial alignment of the shipborne aircrafts. The wireless initial alignment system and the alignment method for the time / inertial navigation of ships and aircrafts can reduce thehidden danger of the flight deck cable interfering with the take-off and landing of the aircrafts, and can improve the aircraft departure rate, thereby improving the combat effectiveness of the ships.

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....
