%X 本文探讨了采用便携式GNSS接收机，增强安卓移动应用程序定位能力的多种方法。基于安卓系统的GNSS定位服务架构和便携式GNSS接收机CORS差分定位流程，本文介绍了便携式GNSS接收机增强安卓移动应用程序包括SDK接入、广播消息、模拟位置、GNSS模组移植在内的四种常用方法的具体实现流程。通过对比分析评估，分析了各个方法的适用场景，评估了各方法的稳定性、兼容性，以及各方法定位信息的可靠性、完备性。研究表明，高精度GNSS定位平板等定制化一体机建议采用GNSS模组移植法，便携式GNSS接收机建议采用SDK接入法。针对这两个方法的缺陷，本文随后给出了优化建议。本研究成果已应用在重庆“国土调查云”测试版中，支撑调查监测业务多样化、个性化的泛在位置服务需求。<br />
This article explores various methods to enhance the positioning capabilities of Android mobile ap-plications using portable GNSS receivers. Based on the Android system’s GNSS positioning service architecture and the portable GNSS receiver CORS differential positioning process, this article in-troduces four commonly used methods—SDK access, broadcast messages, simulated positioning, and GNSS module transplantation—to enhance Android mobile application using portable GNSS re-ceivers. Through comparative analysis and evaluation, the article analyzes the applicable scenarios of each method, evaluates their stability and compatibility, as well as the reliability and complete-ness of the positioning information provided by each method. The research shows that the GNSS module transplantation method is recommended for customized devices such as high-pre- cision GNSS positioning tablets, while the SDK access method is recommended for portable GNSS receivers. The article also provides recommendations to optimize these methods. This research has been ap-plied in the Chongqing “National Land Survey Cloud” test version to support the ubiquitous location service needs of surveying and monitoring businesses with diverse and personalized requirements.
