Advanced relativistic VLBI model for geodesy
Michael Soffel, Sergei Kopeikin, Wen-Biao Han
Our present relativistic part of the geodetic VLBI model for Earthbound antennas is a consensus model which is considered as a standard for processing high-precision VLBI observati…
Planetary Radio Interferometry and Doppler Experiment (PRIDE) Technique: a Test Case of the Mars Express Phobos Fly-by. 2. Doppler tracking: Formulation of observed and computed values, and noise budget
T. M. Bocanegra-Bahamón, G. Molera Calves, L. I. Gurvits +5
Context. Closed-loop Doppler data obtained by deep space tracking networks (e.g., NASA's DSN and ESA's Estrack) are routinely used for navigation and science applications. By "shad…
Application of Time Transfer Functions to Gaia's global astrometry - Validation on DPAC simulated Gaia-like observations
Stefano Bertone, Alberto Vecchiato, Beatrice Bucciarelli +5
A key objective of the ESA Gaia satellite is the realization of a quasi-inertial reference frame at visual wavelengths by means of global astrometric techniques. This requires an a…
Techniques for Accurate Parallax Measurements for 6.7-GHz Methanol Masers
M. J. Reid, A. Brunthaler, K. M. Menten +13
The BeSSeL Survey is mapping the spiral structure of the Milky Way by measuring trigonometric parallaxes of hundreds of maser sources associated with high-mass star formation. Whil…
The Hyper Suprime-Cam SSP Survey: Overview and Survey Design
H. Aihara, N. Arimoto, R. Armstrong +139
Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea in Hawaii. A team of scientists from Japan, Taiwan…
VLBI ecliptic plane survey: VEPS-1
Fengchun Shu, Leonid Petrov, Wu Jiang +12
We present here the results of the first part of the VLBI Ecliptic Plane Survey (VEPS) program. The goal of the program is to find all compact sources within of the ecl…
