1. What Is a UAV?
A UAV (Unmanned Aerial Vehicle) is an aircraft that operates without a pilot onboard. UAVs may be remotely controlled or operate autonomously through onboard flight controllers and navigation systems.
UAVs are part of a broader Unmanned Aircraft System (UAS), which includes:
- The aircraft platform
- Ground control station (GCS)
- Communication system
- Mission payload equipment
Modern UAV systems are designed for efficiency, operational safety, and mission flexibility.
2. Core Components of UAV Technology
