TopoPos plots tracks of radio source and satellites on the sky in horizontal system as seen from ground stations. Lists the azimuth and elevation values. UVPlot produces UV-plot for selected baselines. SpaceView shows a movie of Earth indicating the position of the telemetry stations as seen from the satellite. SkySurv creates a survey for a specified area of the sky deciding if certain parts are observable from ground VLBI stations and satellites or not at a given time.
Access creates a long term survey for a sky area.
It shows how long the certain parts are observable from ground VLBI stations and satellites during a time interval. CheckArc gives information about the possible attitudes of space VLBI satellite when observing a selected radio source during a time interval. It takes the on-board observing constrains into account. Beam selects radio sources within the primary beam of space VLBI antenna for phase referencing purposes. Cone selects radio sources in special geometric configurations with respect to the satellite orbit normal.
