BDSet: a first-ever BDS satellite-based PPP augmentation dataset since 2023

This dataset originates from PPP-B2b augmentation signals collected in Wuhan, China, and covers the processing flow of ‘Raw data → Standardized data → Decoded data → Final products’, i.e. raw data from receiving chip, standardized PPP-B2b augmentation messages, decoded PPP-B2b SSR corrections, and recovered PPP-B2b precise products which can be directly utilized in PNT applications.The BDSet is continuously updating since January 1, 2023. This release covers PPP-B2b augmentation signals up to December 31, 2025.

本数据集源自中国武汉采集的PPP-B2b增强信号（PPP-B2b），涵盖‘原始数据→标准化数据→解码数据→最终产品’的完整处理流程，具体包含接收芯片产出的原始数据、标准化PPP-B2b增强报文、解码后的PPP-B2b状态空间表示（SSR）改正数，以及可直接应用于定位、导航与授时（PNT）场景的恢复得到的PPP-B2b精密产品。本BDSet自2023年1月1日起持续更新，本次发布覆盖截至2025年12月31日的PPP-B2b增强信号数据。
