摘　　要：研制出了一款磁性天线用于解决长河二号监测系统连续监测问题并提高监测精度。磁天线相对于电天线更有利于接收长河二号信号,抑制干扰,提高信噪比,获得较高的时差测量精度,对台链各台发射信号的时间基准的调整更为准确。通过分别在导航台及监测站的试用,验证了磁性天线研制成功。A new long wave magnetic antenna for Chang-He 2 navigation system is developed which have the advantage of overcoming the signal loss and improving the time difference measure precision. Compared with electric antenna, magnetic antenna does well in incepting Loran-C signal, restraining disturbence, advancing SNR, attaining upper precision of time difference measuring, so the time standard can be adjusted more accurately, The results of experiments in NanHui monitor station and XuanChen transmitter station show that the magnetic antenna has better performance than the electric antenna has.
