When a craft has multiple, combinable antennae, the antenna's power ratings stack in a way that provides diminishing returns using the following formula: If (by difficulty setting) there is only one tracking station, a ship must depend on a CommNet relay manally placed around Kerbin, here are the general ranges between antennae. Kerbin's Deep Space Network can be treated as a vessel with a rating of 2G/ 50G/ 250G (depending on the level of the Tracking Station) for the purposes of calculating range. This is calculated as follows: Template:Formula Power ratings for antennae range from 5k for the integrated antenna available in every Command module, to 100G for the largest dishes. A connection can be established between two vessels when the geometric mean of their power ratings is greater than their separation as measured in meters.

Each antenna has a 'power rating', measured as a unitless number, which contributes to the overall power rating of the vessel it is attached to. Individual vessels do not have a fixed maximum range: whether a connection is possible between two vessels that are a given distance apart depends on the transmission strength of the vessels at both ends of the connection. The following table lists the maximum range for vessels with a single antenna signaling the Deep Space Network (note these change with Range Modifier in CommNet difficulty options):Ģ2.36Gm (Moho always, Eve, Duna & Dres (barely) if close)Ģ7.39Gm (Always Moho & Eve, Duna & Dres if close)Ħ1.24Gm (Dres, Jool & Eeloo if close, other planets always)ħ0.71Gm (Jool & Eeloo if close, other planets always) Locations may be linked either through a direct connection or indirectly via one or more relays.

Vessels without a Pilot require a link to a control source for full control (valid control sources are a vessel with an operational Probe Control Point, or more commonly the Deep Space Network on Kerbin).

With CommNet enabled (as a difficulty setting), antennae have limited range from which control and transmission of science data is possible. CommNet is a relay and control communication system implemented first in KSP 1.2 pre-release.
