To overcome the problem that a fixed estimator is contaminated by a system error for the ambiguity be misjudged in the GNSS precise positioning, a reliable integer float estimator is recommended. Accordingly, the method for determining a finite number of integer vectors based on a given reliability probability is proposed, the formula for calculating the variance matrix of the recommended estimator is derived, and the judgment method of the estimator’s availability is proposed. The detailed process and the effect of the method are also demonstrated using examples to facilitate user application.

GNSS精确定位中可靠整数浮点估计量的实用计算方法

为了克服固定误差估计器会因GNSS精确定位中误判歧义而受到系统误差污染的问题，建议使用可靠的整数浮点估计器。因此，提出了一种基于给定可靠性概率确定有限个整数向量的方法，推导了推荐估计量方差矩阵的计算公式，并提出了估计量可用性的判断方法。还通过示例来演示该方法的详细过程和效果，以方便用户应用。
