A relative positioning module (18) applies a real-time kinematic (RTK) algorithm to provide relative position vector between reference receiver and rover receiver and to provide recovery data. At therover, the precise positioning module (16) applies the relative position vector, the aiding data, recovery data, and correction data as inputs, constraints, or both for convergence of one or more predictive filters on wide-lane and narrow-lane ambiguities (e.g., in accordance with a precise positioning algorithm). At the rover, the precise positioning module (16) or the navigation positioning estimator (50) estimates a precise position of the rover based on the converged or fixed narrow-lane ambiguities and wide-lane ambiguities. 相对定位模块(18)应用实时动态(RTK)算法，以提供参考接收器和漫游器的接收器之间的相对位置矢量并提供恢复数据。在漫游器处，(例如，根据精密定位算法)精密定位模块将相对位置矢量、辅助数据、恢复数据和校正数据应用作为输入、约束或两者以用于个或多个预测滤波器在宽巷模糊度和窄巷模糊度上的收敛。在漫游器处，精密定位模块(16)或导航定位估算器(50)基于收敛或固定的窄巷模糊度和宽巷模糊度来估算漫游器的精确位置。
