VLBIvel

VLBIvel is a software application designed for processing and analyzing data collected through Very Long Baseline Interferometry (VLBI), a technique used in radio astronomy and geodesy to achieve extremely high-resolution observations of celestial sources and precise measurements of Earth's orientation and position. The primary purpose of VLBIvel is to facilitate the correlation, calibration, and interpretation of VLBI observations, enabling scientists to study astronomical phenomena and monitor geophysical parameters with unmatched precision.

Developed by a collaborative team of researchers and engineers, VLBIvel integrates advanced algorithms for data correlation, fringe fitting, and delay modeling. It supports various data formats and is compatible with commonly used VLBI data acquisition systems. The software provides a user-friendly interface for scheduling observations, visualizing visibility data, and conducting post-processing analyses.

VLBIvel plays a vital role in diverse scientific applications, including astrometry, celestial reference frame determination, Earth rotation monitoring, and tectonic plate movement studies. Its high computational efficiency and flexibility allow for real-time processing in some configurations, making it suitable for both research and operational purposes.

In addition to its core functionalities, VLBIvel is often integrated into broader geodetic and astronomical data pipelines, contributing to international efforts such as the International VLBI Service (IVS). Its ongoing development focuses on improving processing capabilities, expanding compatibility, and supporting emerging VLBI techniques to advance the frontiers of observational science.
