At the end of the summer 2021, an increase in CO₂ emissions at Vulcano brought an increase in the alert level and, consequently, to the upgrade of the monitoring activities by increasing the number of instruments deployed and the rate of the surveys. One of the new devices installed was a geodetic GNSS mobile network for a real-time and high-frequency monitoring of ground deformation, to increase the detail with respect to the existing permanent network. The mobile stations were initially installed at the northern base of the La Fossa crater, where the highest values of soil degassing were recorded. Two stations were co-located with gravimeters, in order to compare and integrate the data. After this very first period of testing, the mobile GNSS array has been reconfigured, to investigate the mud pool area. Thus, four stations were installed around the degassing area, one of them being in the same site of the gravimeter. Data has been acquired at 1 Hz rate and is used for the weekly reporting to Civil Protection. It was the first experience of a light and quick-to-install geodetic real-time and high-rate GNSS mobile network in this area, and it was the occasion for testing its performance, as well as different approaches for the real-time kinematic (RTK) differential positioning in order to find the most suitable for the ongoing phenomena. Furthermore, direct data communication and archiving in the institutional database have been implemented for immediate querying from the control room tools. We report the experiences collected during the installation phase, site selection, RTK approaches, and ground motion and provide the daily raw data in RINEX format for any future precise postprocessing for the mid- to long-term analyses.

2021 年夏末，武尔卡诺 CO ₂排放量的增加导致警报级别提高，从而通过增加部署的仪器数量和调查率来升级监测活动。安装的新设备之一是大地测量 GNSS 移动网络，用于实时高频监测地面变形，以增加现有永久网络的细节。移动站最初安装在拉福萨火山口的北部底部，那里记录了土壤脱气的最高值。两个站与重力计位于同一地点，以便比较和整合数据。经过第一阶段的测试后，移动 GNSS 阵列已重新配置，以调查泥浆池区域。因此，在脱气区域周围安装了四个站，其中一个与重力计位于同一位置。数据以 1 Hz 的频率采集，用于每周向民防部门报告。这是该领域首次体验轻型、快速安装的大地测量实时高速GNSS移动网络，也是测试其性能以及实时运动学的不同方法的机会。 (RTK) 差分定位，以便找到最适合正在进行的现象。此外，机构数据库中已经实现了直接数据通信和存档，以便从控制室工具立即查询。我们报告在安装阶段、选址、RTK 方法和地面运动过程中收集的经验，并以 RINEX 格式提供每日原始数据，以便将来进行中长期分析的精确后处理。
