Scheduling of Twin Telescopes and the Impact on Troposphere and UT1 Estimation

• Recently, several VGOS twin telescopes in Europe were completed.We examine the use of VGOS twin telescopes by a new scheduling approach. This approach is based on integer linear programming and creates uniform distributed observations over time. Several VLBI intensive sessions are rescheduled involving the VGOS twin telescopes and the impact on the troposphere and UT1 estimation is investigated.
