摘要: [目的] 本文旨在评估不同电离层改正产品对智能手机单频GNSS标准单点定位性能的提升效果。[方法] 以华为Mate40与vivo iQOO智能手机为测试终端,对比分析基于广播星历的Klobuchar模型与国际GNSS服务提供的实时(RT-GIM)、快速(RAP-GIM)及最终(FIN-GIM)全球电离层图产品在标准单点定位中的表现。[结果] 在Klobuchar模型改正下,华为Mate40与vivo iQOO智能手机在北、高方向的RMSE分别为3.85、8.25 m和5.76、8.33 m;使用RT-GIM后,分别降至2.35、6.61 m和3.87、6.45 m;采用FIN-GIM可进一步优化至2.29、6.42 m和3.47、5.94 m,RAP-GIM性能与之接近。[结论] IGS电离层产品显著优于Klobuchar模型,其中FIN-GIM综合表现最优,可为智能手机及单频GNSS终端定位提供有效参考。

Abstract: [Purposes] This paper aims to evaluate the enhancement effect of different ionospheric correction products on the performance of smartphone single-frequency GNSS standard point positioning. [Methods] It used Huawei Mate40 and vivo iQOO smartphones as test terminals.A comparative analysis was conducted on the performance in SPP using the broadcast ephemeris-based Klobuchar model and the real-time (RT-GIM),rapid (RAP-GIM),and final (FIN-GIM)global ionospheric map products provided by the International GNSS Service. [Findings] With the Klobuchar model,the positioning RMSE for the Huawei Mate40 and vivo iQOO smartphones were 3.85 and 8.25 m,and 5.76 and 8.33 m in the north and up directions,respectively.When using RT-GIM,they decreased to 2.35 and 6.61 m (Huawei Mate40),and 3.87 and 6.45 m (vivo IQOO).The use of FIN-GIM further optimized the performance to 2.29 and 6.42 m (Huawei Mate40),and 3.47 and 5.94 m (vivo iQOO),with RAP-GIM showing similar performance. [Conclusions] The IGS ionospheric products are significantly superior to the Klobuchar model,with FIN-GIM demonstrating the best overall performance,providing an effective reference for positioning in smartphones and other single-frequency GNSS terminals.
