the all-frequency rapid code/phase bias products (i.e., WUM0MGXRAP )
containing quantities for the discontinuity of orbits, clocks and code/phase
biases (DOCB) as an integral at day boundaries. The Wuhan IGS AC/DC has
released such products since day 001, 2024 on <a href="ftp://igs.gnsswhu.cn/pub/whu/phasebias" style="color:rgb(5,99,193)" target="_blank">ftp://igs.gnsswhu.cn/pub/whu/phasebias</a>. The
products from 2020 to 2023 are also being reprocessed. Details on such DOCB
quantities refer to <a href="http://pride.whu.edu.cn/ueditor/jsp/upload/file/20240906/1725615296863059719.pdf" style="color:rgb(5,99,193)" target="_blank">http://pride.whu.edu.cn/ueditor/jsp/upload/file/20240906/1725615296863059719.pdf</a>. <span lang="EN-US">Note that this quantity and
its format are still tentative and may change. Users can safely ignore them without
