I. Introduction
In recent years, with the widespread application of intelligent technology, intelligent unmanned systems such as unmanned vehicles, drones and robots have also flourished. Navigation algorithm is one of the most important components of intelligent unmanned systems, which can provide the necessary navigation parameters for unmanned systems during motion and ensure their safe and stable movement. In order to evaluate the performance and feasibility of the navigation algorithms, researchers need to test the algorithms under corresponding conditions and environments. However, the implementation of algorithms in actual systems for verification features high cost and low efficiency [1]. Navigation simulation demonstration system can provide an efficient and low-cost demonstration verification method for navigation algorithm research, and support the evaluation of the performance and feasibility of navigation algorithms.
