GNSS-R data at the Onsala Space Observatory (June 2024–July 2025)

This dataset contains 5-second GNSS observations and supporting measurements collected at the Onsala Space Observatory, Sweden, from June 2024 to July 2025. The data are provided to support GNSS-IR and coastal sea-level studies. The collection includes four components: ONRA 5-second RINEX 3 GNSS data from the horizon-pointing, choke-ring antenna, optimized for GNSS-IR. ONRB 5-second RINEX 3 GNSS data from the zenith-pointing, choke-ring antenna for precise positioning. OSOU 5-second RINEX 3 GNSS data from the long-running GNSS-IR installation at the Onsala Space Observatory. Tide gauge and weather data, including 1-minute tide-gauge sea level and 1-minute meteorological data.本数据集包含2024年6月至2025年7月于瑞典翁萨拉太空天文台（Onsala Space Observatory）采集的5秒级全球导航卫星系统（GNSS）观测数据及配套测量数据，旨在为GNSS反射测量（GNSS-IR）与沿海海平面研究提供支撑。 数据集包含四个组成部分： ONRA：面向地平指向型扼流圈天线采集的5秒级RINEX 3格式GNSS数据，专为GNSS反射测量（GNSS-IR）应用优化。 ONRB：面向天顶指向型扼流圈天线采集的5秒级RINEX 3格式GNSS数据，用于精密定位。 OSOU：来自翁萨拉太空天文台长期运行的GNSS反射测量（GNSS-IR）观测装置的5秒级RINEX 3格式GNSS数据。 验潮仪与气象数据，包含1分钟分辨率的验潮仪海平面观测数据与1分钟分辨率的气象观测数据。
