Abstract

The invention belongs to the technical field of aerial inertial navigation devices, and relates to a calibration reminding method of an aerial inertial navigation device. The inertial navigation device samples satellite positioning data in a timing mode and compares the satellite positioning data with the position solved by an inertial channel formed in the inertial navigation device, the task radial error rate of a single navigation task is counted according to the radial error rates of all moments, and in case of the radial error rates of accumulated over eight tasks, accumulated circular probable errors are counted; when the task radial error rate or the accumulated circular probable errors exceed a specified value, a data bus transmits a calibration prompt to a display system for displaying. The problem that inertial navigation device navigation precision inspection needs to be completed by professional technical personnel through a professional external detection device is solved. The maintenance cost can be effectively controlled, the maintenance cycle can be shortened, and the requirements on the professional skill level of maintenance personnel can be lowered.

Description

technical field

[0001] The invention belongs to the technical field of aviation inertial navigation devices, and relates to a calibration reminder method for aviation inertial navigation devices. Background technique

[0002] The navigation accuracy inspection method of the inertial navigation device is mainly to check the navigation accuracy of the inertial navigation device by professional and technical personnel through a special external detection device, and judge whether it is greater than or equal to the specified value. Due to the use of a special external detection device in this method, the cost of use and maintenance is high, and the professional technical level of the maintenance personnel is relatively high. The maintenance personnel must undergo professional training before they have the qualification to operate the special equipment. Contents of the invention

[0003] The technical problem solved by the invention is to provide an easy-to-operate calibration ...
