摘要
在GPS定位中,周跳的探测和修复是获得高精度定位结果的前提。针对载波相位周跳数据的探测和修复这一问题已经提出了很多方法,但都有各自的不足之处。文中针对恶劣环境下的载波相位定位问题,通过使用多个历元的数据构建方程,提出一种新的整周模糊度定义方法,并预期能够在仅有3颗可用卫星且周跳发生时实现快速、准确的定位。
Cycle slip detection and repair is the prerequisite for obtaining high-precision positioning results in GPS positioning.Many methods have been proposed for the question of detection and repair of the cycle slips data in carrier phase,but they all have their own shortcomings.Aiming to accurate positioning fast with three satellites when the date generate cycle slips,this paper propose a new method to define the integer ambiguity,through construction equations by using multiple epochs data,for the carrier phase positioning in harsh environments.
