Calibration reminding method of aerial inertial navigation device

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 ca
