With the previously-failed launch of IP ComSat I, the second craft already under construction was used for its replacement. The purpose of these satellites is to achieve extremely elliptical polar orbits in order to spend the maximum amount of time above/below Kerbin for best possible line of sight to other planets in the Kerbol system. A dish capable of reaching as far as Eeloo is included on each satellite, as well as two smaller dishes to help connect craft traveling around the Kerbin system. In addition to placing IP ComSat in orbit, some existing hardware up in LKO was re-purposed to help create a more redundant communications network around Kerbin.
