中文摘要：

与全球定位系统（GPS）不同的是全球导航卫星系统（GLONASS）的P码未加密，向所有用户开放，更有利于时间比对。结合国内外需求，中国科学院国家授时中心研制了GPS／GLONASS时间传递接收机NTSCGNSS-2。介绍了GLONASS信号特点和对NTSCGNSS-2的初步测试结果。

英文摘要：

The GLONASS P-code is not encrypted and is broadly accessible, which is different from GPS and is more beneficial to time transfer. In view of the domestic and external demands, the GPS / GLONASS time transfer receiver NTSCGNSS-2 has been developed at the National Time Service Center （ NTSC ）. The character of GLONASS signals and the preliminary test of the NTSCGNSS-2 are introduced in this paper.
