Kerbin Relay Network

The Kerbin Relay Network is a relay constellation made up of about a dozen relays orbiting Kerbin in various orbits. The Kerbin Relay Network serves as a communication link from the KSC to crafts in orbit, in the planetary system, and the rest of the solar system.

The KRN is made up of several series of relay probes, with each set fulfilling a different purpose. These probes are part of a connected network that makes sure communications reach KSC regardless of position.

Lagrange Network
The largest probes, and most recently launched are the 3 Lagrange relays. These satellites orbit at Kerbin's 3 L3, L4, and L5 Lagrange Points. These probes were the last probes to be launched, being launched individually on board the then newly completed Hermes IV rocket.

The L3 relay was launched ontop of the Artemis VIII rocket, and a much larger and special made relay.

These probes use the IX-6315 "Dawn" engines, the same engines used on the Intrepid NDS. These probes are meant for long term use, are are used to communicate signals from the farthest parts of the solar system to the next satellite. Barring mechanical failure, the crafts have enough ion fuel to maintain their orbits for millennia.

The 3 Lagrange relays are:

B-Tier
The backbone of the solar net and some of the most valuable Scientific Satellites belong to the Juno-Series Relays. There are 4. These relays were launched on the Explorer-Class Shuttles in 2 launches due to limited fuel to space them out. These relays orbit in a 4 point polar orbit, and carry M700 Surface Scanners.

These serve as a real time source of below ground information on Kerbin.

C-Tier
The smallest and most numerous probes are the Cancer-Series Probes. These are small probes, meant for f
