Abstract
The present disclosure provides a navigation method and system for caterpillar-type agricultural machinery during loss of a navigation real-time kinematic (RTK) signal, falling within the technical field of vehicle navigation. The method includes the steps of: S1, acquiring operation parameter information about the caterpillar-type agricultural machinery before signal loss, and adjusting a state of the caterpillar-type agricultural machinery based on the operation parameter information; and S2, calculating an operation deviation amount after adjusting the state of the caterpillar-type agricultural machinery for a time t. In the present disclosure, deviation operation caused by signal loss during large-scale operation of agricultural machinery can be improved, and problems in regional scale planting can be prevented.
