The Moon 2.0 Simulator (see announcement from last week) has been updated to support ground stations for communications.
Main menu→View→Stations — allows you to enable / disable ground stations
Main menu→Options→Stations — allows you to choose between the available networks
When ground stations are enabled, green markers represent ground stations within range of the spacecraft and red markers represent ground stations out of range. You will also see a straight line connecting the spacecraft and the ground station when they are within range.
The updated package comes with a database of existing commercial and governmental ground station networks but you can easily add your own stations. The data file Stations.csv contains comma-separated values in plain text format that can be edited using a spreadsheet application or a simple text editor.
The video below shows an example simulation "Picorover to the Moon" with ground stations enabled.
