Tutorial:Setting up a CommNet system

Setting up a CommNet system

With the addition of CommNet, you need a system of relays to connect back to the KSC. Here's how to set up a constellation of satellites to ensure complete coverage.

Creating a satellite

• Start with an RC-001S probe core
• Underneath, add a reaction wheel and a few z-1k battery banks
• Add some Gigantor-XL solar panels around the outside. 3 panels is enough for near Kerbin, but you'll need more if you go farther out.
• Add a relay satellite on the top (RA-2, RA-15 or RA-100, depending on range)
• Done!

Triangle orbit

A triangle orbit will be the main orbit used in the constellations. It consists of three co-orbital satellites, 120 degrees apart. The orbital altitude must be greater than the radius of the body you are orbiting.

Constellations

Each system needs its own constellation.

Kerbol

A set of six evenly space relays at around 4,000,000km. A set of twelve evenly spaced relays at around 25,000,000km. A set of 24 evenly spaced satellites at around 50,000km. Use RA-100 relays. These relays are for connecting with deep space probes. You may omit the third ring but deep space coverage in the outer system may be a bit spotty.

Moho

Equatorial triangle orbit above 250,000m. Polar triangle orbit above 250,000m. Use RA-2 relays.

Eve and Gilly

Eve

Equatorial triangle orbit above 700,000m. Polar triangle orbit above 700,000m. Use RA-2 relays.

Gilly

Equatorial triangle orbit above 13,000m. Polar triangle orbit above 13,000m. Use RA-2 relays.

Kerbin system

Kerbin

Equatorial triangle orbit above 600,000m. Polar triangle orbit above 600,000m. A second equatorial triangle orbit at around 60,000,000m. Use RA-2 relays.

Mun

Polar triangle orbit above 200,000m. Use RA-2 relays.

Minmus

Polar triangle orbit above 60,000m. Use RA-2 relays.

Duna and Ike

Duna

Equatorial triangle orbit above 320,000m. Polar triangle orbit above 320,000m. Use RA-2 relays.

Ike

Equatorial triangle orbit above 130,000m. Polar triangle orbit above 130,000m. Use RA-2 relays.

Dres

Equatorial triangle orbit above 138,000m. Use RA-15 relays. Polar triangle orbit above 138,000m. Use RA-2 relays.

Jool system

Jool

Equatorial traingle orbit above 6,000,000m. Polar orbit above 6,000,000m. Use RA-2 relays. A second equatorial triangle orbit at around 300,000,000m. Use RA-100 relays.

Moons

Polar triangle orbit. Altitude depends on moon (500,000m for Laythe, 300,000m for Vall, 600,000m for Tylo, 65,000m for Bop and 44,000m for Pol). Use RA-2 relays.

Eeloo

Equatorial triangle orbit above 210,000m. Use RA-100 relays. Polar triangle orbit above 210,000m. Use RA-2 relays.

Final word

With a 2G antenna on probe, this should give you complete coverage within planetary spheres of influence. Deep space coverage may not be perfect. With a 15G antenna, you get much better deep space coverage. Adding additional relay rings around Kerbol should also help with coverage.
