摘要/Abstract

摘要： 在高动态网络RTK定位中，VRS虚拟参考站随着用户位置的快速变化而频繁变化，这使得用户端RTK定位需频繁初始化，导致连续性不足。针对这一问题，本文研究了一种在主参考站不变时，虚拟参考站无需因动态用户位置的变化而变化的算法。首先在网内固定一个虚拟参考站，为用户在已固定的虚拟参考站处生成虚拟观测值，然后将用户真实位置与虚拟参考站之间的大气延迟修正至虚拟观测值。利用天津CORS实测数据对算法进行验证，结果表明，本文算法与传统算法初始化时间相同，定位精度相当。相比传统虚拟参考站生成算法，本文提出的算法有两个优势：一是在主参考站不发生变化的情况下，可使虚拟参考站保持不变，从而使得动态用户无需重新初始化；二是只需对网络RTK中心软件进行升级，而无需对当前处于实际应用中的RTK终端作任何改进便可被兼容。

关键词: 虚拟参考站不变, 网络RTK, 重新初始化

Abstract: In kinematic network RTK (NRTK) positioning, when users move rapidly, the virtual reference station (VRS) also need to be changed frequently. This will lead to the frequent initialization and damage the continuity of RTK positioning. In this paper, we proposed a modified algorithm which can overcome this shortcoming. Firstly, a fixed VRS was selected in the network cell where the user was located. Then, the virtual observations was generated at this virtual station. Lastly, the differential atmospheric delay between user's actual position and this virtual station was corrected. The performance was tested with Tianjin CORS. The results showed that the positioning accuracy and initialization time using the proposed algorithm was comparable to the traditional VRS algorithm. However, the proposed algorithm had two obviously advantages. The first one was that users do not need to reinitialize as long as the main reference station was not changed. The second one was that only the software in NRTK center needed to be upgrade, instead of any improvement in the RTK terminals.

Key words: fixed VRS, network RTK, reinitialization
