Prospects of IVS-Intensive Sessions with Twin-Telescopes

The Wettzell-Twin-Telescope (TTW) is currently being assembled and is expected to become operational in late 2012. The TTW promises various observation scenarios that might strengthen the parameters estimated from the observation. This is especially true for the one hour Intensive Sessions IVS-INT3 where observations are performed on three baselines with the radio telescopes NYALES20, TSUKUB32 and WETTZELL. For this session type, the number of observations will be significantly increased and the local hemisphere above either telescope will be covered in a better way. We investigate optimization scenarios for TTW within the INT3 sessions. We will present various scheduling and simulation approaches for the IVS-INT3 sessions. The schedules are done with an automatic scheduling procedure that is based on the analysis of the variance-covariance matrix of the estimated parameters. Furthermore, the handling of local TTW-specific parameters, i.e., clocks and troposphere, will be investigated. The results will be validated by thorough analyses of the UT1 estimates.
