角内插点最佳点位及其可靠性规律

Law of the Optimum Inner-angle Insert Point Location and Its Reliablility

通过测角后交、三点前交、角度全测三种角内插点的误差分析，得出了角内插点最佳点位分布规律，并分析了插点观测值的可靠性，为角内插点测量提供了依据。

Through the error analysis of three kinds of inner-angle insert point measurements,namely,the back-intersection angle,the three-point frontintersection angle and the whole angle,the law of optimum inner-angle insert point distribution is drawn and the reliablity of insert point observation values is analysed,which provides the basis for implementing inner-angle insert point measurement.
