Abstract
The inception of the VGOS R&D program in 2021 marked a pivotal milestone in the evolution of VGOS. This work serves as a catalyst for an interactive discussion, providing a platform to discuss lessons learned from these sessions while charting pathways for future VGOS observations and operational integration.Our focus revolves around the outcomes gleaned from the six VGOS R&D sessions conducted in 2022. These sessions aimed at optimizing the number and distribution of observations and scans, resulting in a significant augmentation, with observations and scans more than doubling compared to conventional VGOS sessions while simultaneously reducing the number of recorded bits. Noteworthy enhancements were observed in Earth orientation parameter estimates, showcasing improved alignment with IERS solutions and SX observations, coupled with bolstered baseline length repeatability and reduced formal errors.Furthermore, our exploration delves into the pioneering two sessions of 2023, trialing source-based VLBI scheduling. This initiative aimed at expanding the VGOS source list through the integration of new ICRF3 sources while amplifying imaging capabilities.Our findings underscore the pivotal advantages of equitably distributing observations among sources, presenting compelling benefits for the VGOS framework.This poster serves as an invitation to engage in a discussion that encapsulates the successes and insights derived from the VGOS R&D sessions. It aims to stimulate discourse on strategies for seamless integration into operational VGOS sessions, fostering a collaborative environment to utilize VGOS capabilities for future scientific endeavors.
