Once the Telemachus data link part is installed...
...you can connect to a telemetry source using your web browser, to obtain several visualisations...
...and then combine them to construct your own mission control. In the image below we have an example of such a setup:
From left to right you have: Atmospheric density chart, KSP (obviously), Altitude chart, and a g-force chart on the tablet perched on the shelf. The following screen shots show more Telemachus features.
Figure 1 - Send basic commands to your vessels
Figure 2 - MechJeb2 integration
Figure 3 - Kerbal Maps integration
For Compliance of Add-on Rule 5
In case it wasn't obvious already, Telemachus sends telemetry data from KSP to a web browser. If you require precise information on the data exchanged and the protocols used, then please check out the API Documentation.
