Disclosed is a device and a method for a UAV only by a navigation device. A global navigation satellite system (GNSS) satellite signal receiving module for receiving a GNSS satellite signal in the first direction received from a first direction; A jamming signal generation module for generating a jamming signal by delaying a GNSS satellite signal received by the GNSS satellite signal receiving module by a predetermined time; And transmits the jamming signal generated by the jamming signal generation module in a second direction opposite to the first direction. According to the apparatus and method for unmanned aerial induction only by the above-described satellite navigation device, the GNSS satellite signal inputted in the direction of the friendly zone is delayed and transmitted by the UAV, thereby making it mistaken that the UAV is closer to the enemy area This has the effect of inducing the UAV to move continuously to the friendly zone. Therefore, by increasing the time during which the unmanned aerial vehicle swings in the friendly area, there is an effect that the user can fall or be captured in the friendly area.
