Real-time oceanic PWV sensing using BeiDou-3 PPP-B2b and low-cost GNSS devices

This dataset consists of two parts, GNSSDATA and RESULT, which were utilized in the manuscript: "Real-time oceanic PWV sensing using BeiDou-3 PPP-B2b and low-cost GNSS devices."

GNSSDATA: This dataset contains shipborne BeiDou/GNSS data spanning four days, from 00:00 on September 21 to 00:00 on September 25, 2023. The data was collected using a low-cost GNSS receiver, the Septentrio mosaic-X5, and is stored in Septentrio Binary Format (SBF). The raw BeiDou/GNSS observations, PPP-B2b corrections (orbits/clocks/code bias), and broadcast ephemeris can be decoded from the SBF format using Septentrio RxTools.

RESULT: This dataset includes the PPP-B2b-derived zenith tropospheric delay (ZTD) solutions obtained from the above GNSS data, based on the five schemes designed in the manuscript.
