| Abstract: | An L-band safety remote control system is introduced which is composed of three stations and one center in order to increase coverage and overcome the limit of earth curvature to intervisibility. In the system such measures as wide beam, forward error correction, new L-band, integrated baseband, large power tolerance and remote transparent monitoring are adopted, so the reliability of system is improved and the system has excellent performance. |
