| 摘 要： | 根据残差二次型次小与最小之差进行整周模糊角度确认的关键是差值的分布，只有得到了合理的差值分布才可确定合理的界值。文中基于原有的两种方法及这两方法的不足，从理论上导出了满足条件的差值分布，并作了一定的说明。

| Abstract: | The key problem is the distribution of the difference between the second minimum and the minimum quadratic form of residual in the validation of the ambiguity for the GPS measurement. The bounded value of the statistic distribution is obtained suitably only based on the reasoned distribution. The difference distribution has been derived in the light of conditions of the difference and the shortages of the two basic methods with some explanations. |
