VGOS Technology R&D Sessions

Abstract

A series of VGOS technology R&D sessions has been undertaken. In total, seven 24-hour sessions were scheduled along with associated 1-hour tests. The primary goal is to significantly increase the number of observations per session at each station. In the VGOS R&D series so far, the number of observations per ses sion has more than doubled when compared to cur rent operational VGOS sessions. Other related priori ties include: 1) to optimize high rate schedules both for geodesy and for imaging; 2) to develop and test pro cesses to determine and apply source structure correc tions; and 3) to evaluate and test improved frequency sequences. Sources were analyzed to produce closure images, maps, models, and preliminary corrections.
