This paper presents the concept of precise navigation based on SBAS technology and CORS stations. In a kinematic test, three rover Global Positioning System (GPS) receivers, properly spaced relatively to each other, were used in order to estimate reliable and redundant GPS/EGNOS positions. Next, the Kalman filter was employed to give the final solution. It was proven that EGNOS positioning allows to obtain an accuracy in the range of about 0.5-1.5 m. The proposed solution involving the use of three mobile receivers and Kalman filtering allowed to reduce the 3D error to a level below 0.3 m. Such an accuracy was achieved using only GPS L1 code observations and EGNOS corrections. Additionally, a reliable monitoring of quality of GPS/EGNOS positioning in the test area based on CORS stations was presented.
本文介绍了基于卫星增强系统（SBAS）技术和连续运行参考站（CORS）的精确导航概念。在一次动态测试中，使用了三个相互间距适当的流动站全球定位系统（GPS）接收机，以估计可靠且冗余的GPS/欧洲地球静止导航重叠服务（EGNOS）位置。接下来，采用卡尔曼滤波器得出最终解决方案。结果证明，EGNOS定位能够获得约0.5-1.5米范围内的精度。所提出的涉及使用三个移动接收机和卡尔曼滤波的解决方案能够将三维误差降低到0.3米以下的水平。仅使用GPS L1码观测值和EGNOS改正就实现了这样的精度。此外，还介绍了基于CORS站对测试区域内GPS/EGNOS定位质量进行可靠监测的情况。
