A preliminary evaluation has also been carried out on the impact of the cutoff angle in VLBI observations. Tierno Ros et al. (2013) have taken a 16-station network and they have created schedules (source based with four sources) with cutoff elevation angles 5, 10, 15, and 30 degrees elevation. They find the best results in terms of baseline length repeatabilities for cutoff angles 10 and 15 degrees.

- Tobias Nilsson is going to implement a Kalman filter to VieVS. It will be highly interesting to test the Kalman filter for VLBI2010 simulations.
