CommNext is a complete CommNet (KSP connection system) overhaul, inspired by KSP1 dynamics and additional utilities to make it easier to use.

Now connections between vessels need to be in line of sight (so celestial bodies can block the connection). Implementation has been crafted to be optimized, so don't worry about performance, just make sure you have moar sats!

Not every vessel can bounce signal to another one: you'll need relays! In the spirit of KSP1, only dish antennas (RA-2, RA-15, RA-100) are allowed to relay signal. You'll need to setup a relay network in order to bring your missions farther in space.

Use the Map View CommNext toolbar to inspect your network:

• Click on the Dish icon to cycle through lines display mode (All active connections, Only active vessel path, Hide lines)
• Use the Ruler icon to toggle Range spheres: each relay will show its range with a yellow sphere (when it's connected) or a red sphere (when it's disconnected from the network)
• Use the Report icon to open the Vessel Comms Report window, which will show all the connections from and to the current vessel. It will help you to check if some possible connections are blocked by a celestial body, or if there is not enough power in a relay.
