Abstract

Pseudorange is the pseudo distance between a GPS satellite and a GPS receiver to determine the receiver's position. The closer the distance between jammer and victim receiver is, the more effective a repeat-back jamming is. In this letter, we analyze the pseudorange difference between adjacent GPS receivers using real GPS pseudorange data to understand the effects by the repeat-back jamming.

의사거리는 GPS 수신기의 위치를 결정하기 위한 오차를 포함해 측정된 GPS 위성과 수신기 사이의 거리이다. 재방송 재밍기는 GPS 수신기에 가까이 있을 때 효과적으로 동작한다. 본 논문에서는 재방송 재밍의 원리를 효과적으로 이해하기 위해 근접한 GPS 수신기의 의사거리 차를 분석한다.
