摘　　要：北斗卫星导航系统是中国自行研制的继美国GPS和俄罗斯GLONASS之后第三个成熟的卫星导航系统。三频北斗数据的应用,极大地丰富了模糊度解算方法。三频数据的最大优点在于可以构成多组超宽巷组合观测值,这些组合后的观测值模糊度容易固定,同时还具有很高的观测精度,便于精密定位解算。本文利用实测北斗三频数据,基于无几何模型和几何模型给出了长距离基线实时解算的方法。结果显示基于三频北斗数据的长基线解算能实现上百公里长基线厘米级的定位精度。The Bei Dou Navigation Satellite System（ COMPASS） is Chinese self-developed satellite navigation system after the U. S. Global Positioning System（ GPS） and the Russian GLONASS. The application of Bei Dou triple frequency observations greatly enriched the methods of ambiguity resolution.The advantage of triple frequency observations is that it can form many extra wide lane combination observations,and the ambiguities of these combination observations are easy to fix,it facilitates precise positioning solver. In this paper,we present an instantaneous solution method of long range baseline based on Geometry-free and Geometry-based model. The results show that this instantaneous solution method based on Bei Dou triple frequency observations can achieve centimeter-level positioning accuracy for long range baseline about one hundred kilometers.
