| 中文摘要: |
| 为改善接收机自身定位性能，提高市场竞争力，全球导航卫星系统（GNSS）导航型接收机研制过程中需进行大量的定位测试和对比分析。动态情况下，接收机运动轨迹和实际接收的卫星信号质量实时变化，因此，传统的信号模拟器仿真测试方法不足以真实地反映接收机的定位性能。为反映各接收机的实际动态单点定位性能并能进行接收机对比研究，设计了一种动态单点定位性能对比测试方法，以轿车为移动载体在实际信号和真实环境中进行了验证试验。试验结果表明该方法可从观测数据质量和单点定位精度两方面实现三种导航型接收机的动态单点定位测试和定位性能对比。 |
| 英文摘要: |
| During the development of global navigation satellite system (GNSS) receiver, a large number of tests and comparative analyses need to be carried out to improve the receiver performance and enhance market competiveness. Under kinematic conditions, the motion trajectory of the receiver and the actual received satellite signal quality change in teal time, therefore, the traditional signal simulator simulation test is not sufficient to truly reflect the kinematic positioning performance. In order to reflect the actual positioning performance of each receiver, a kinematic single point positioning performance comparison test method was designed, The verification test was carried out in real signal and real environment with car as the mobile carrier. The results showed that the method could realize the positioning test angle performance in terms of observation data quality and positioning accuracy. |
