Prospective study of high geodetic resolution to future VGOS reference point determination

Geodesy and Geodynamics, 2019
The fast slewing rate and wide band of the VLBI2010 Global Observing System (VGOS) telescopes are beneficial to procure more observations and to obtain VLBI reference points (RPs) of high precisions.

Bridging astronomical, astrometric and geodetic scheduling for VGOS

Journal of Geodesy, 2023
AbstractVery Long Baseline Interferometry (VLBI) experiments are organized within the geodetic, astrometric and astronomical communities for different applications, requiring different observation strategies adopted in scheduling. Currently, the next-generation geodetic and astrometric VLBI Global Observing System (VGOS) is being established.

Geodetic data analysis of VGOS experiments

2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021
Very Long Baseline Interferometry (VLBI) serves as one of the common geodetic methods to define the global reference frames and monitor Earth's orientation variations. The technical upgrade of the VLBI method known as the VLBI Global Observing System (VGOS) includes a critical re-design of the observed frequencies from the dual band mode (S and X band,

Mathematical Modeling of a VGO Hydrotreating Reactor

SPE Latin American and Caribbean Petroleum Engineering Conference, 2001
Abstract This paper presents a mathematical model developed for the operating simulation of a trickle-bed reactor. Furthermore, the model has been fixed to emulate the operation of the three reactors used at the gas oil hydrotreatment reactors available at Amuay refinery (PDVSA).

Scheduling for VGOS twin-telescopes

2016
The technique of Very Long Baseline Interferometry (VLBI) allows the estimation of all five Earth Orientation Parameters (EOP), the International Celestial Reference Frame (ICRF) and it is a primary contributor to the International Terrestrial Reference Frame (ITRF), in particular with information about its scale.
