The compatibility of DORIS with VGOS

The compatibility of DORIS with VGOS The most precise global geodetic reference frame, the International Terrestrial Reference Frame (ITRF), is based on four space geodesy techniques: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite Systems (GNSS) and the Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) System. All four techniques complement […]

Assessing The Consistency Of The Conventional Reference Frames (Terrestrial And Celestial) And Their Impact On Estimated EOP Using VLBI-Based Data

Assessing The Consistency Of The Conventional Reference Frames (Terrestrial And Celestial) And Their Impact On Estimated EOP Using VLBI-Based Data The conventional International Terrestrial Reference Frame (ITRF) is based on the combination of solutions from several space geodetic techniques, including observations until the end of 2020, and incorporates updated data and models. In contrast, the

Performance of the VGOS radio telescope with as-built feed and geometry using electromagnetic simulation

Performance of the VGOS radio telescope with as-built feed and geometry using electromagnetic simulation This paper reports on electromagnetic simulations performed of the as-built VGOS (VLBI Global Observing System) 13.2-metre Radio Telescope at the Hartebeesthoek Radio Astronomy Observatory (HartRAO). Specifically, the telescope performance with a measured quadruple-ridge flared horn (QRFH) and with actual surfaces and

VLBI-Based Assessment Of The Consistency Of The Conventional EOP Series And The Reference Frames (Terrestrial And Celestial)

VLBI-Based Assessment Of The Consistency Of The Conventional EOP Series And The Reference Frames (Terrestrial And Celestial) The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) envisages stringent goals for the International Terrestrial Reference Frame (ITRF) realization in terms of accuracy (1 mm) and precision (0.1 mm/year). These requirements entail that
