摘要
实时动态相对定位(RTK)以其精度高的特点广泛适应于精密RTK测绘和高精度导航等领域。为了保证系统的完好性,基准站设置多台基准接收机,因此需要选取状态最优的基准接收机用于RTK定位的基准。在多基准接收机条件下,本文提出了完好性算法结合残差以及多基准优选的方法生成RTK报文,优选出状态最好的基准接收机,确保播发的报文数据质量高且卫星数多。该方法经过多次故障加注试验,验证了该方法能够优选出综合状态最佳的基准接收机作为基准,从而保证移动站的定位精度和定位成功率。
Real-time kinematic relative positioning with its high precision features widely used in precision RTK mapping and high-precision navigation and other fields. In order to ensure the integrity of the system, base station sets multiple reference receivers. Therefore, it is necessary to select the best reference receiver. Under the conditions of multi-reference receivers, this paper presents integrity algorithm combined with residuals and an optimized selection method for multi-reference receiver to select the best receiver. Through several tests, it was verified that this method can avoid the risk of integrity, thus ensuring the positioning accuracy and positioning success rate of the rover.
