초록

This study examines the development of an integrated navigation system for stable drone operations in GPS-denied environments, which has emerged as a new threat in modern warfare. The research categorizes GPS disruption into jamming, spoofing, and meaconing, analyzing their characteristics and threat levels. As a technical countermeasure, we propose a multi-sensor fusion system based on Inertial Navigation System (INS). The architecture of the integrated navigation system is designed around an Extended Kalman Filter-based fusion algorithm that integrates real-time data from various sensors, including visual sensors, LiDAR, and ultrasonic sensors. Furthermore, we systematize the operational concept for drone operations in GPS-denied environments into three phases: pre-planning, real-time response, and post-action measures, while specifying training system establishment and performance evaluation methods. The findings of this study are expected to serve as foundational material for enhancing the survivability and operational effectiveness of future drone combat systems.
