KSP 0.25: Continued adventures with Remote Tech, FAR, and hard mode
by Wuphon's Reach
There are (3) sats in 700km altitude orbits around Kerbin (the innermost ring of three) that have 2.5Mm range omni-directional antennas installed.
I need to put up a 4th to fill in that hole in the coverage. Right now, depending on view angles, a newly launched probe will be out of communications for about 60 degrees of LKO (low Kerbin orbit). This is not a real big deal as long as the Ap/Pe values are above 70km for the new launch. If the Ap (Apoapsis) node comes around at an awkward time when both KSC and all of the LKO mesh network stats are not visible, I can just wait for the next orbit.
On the right side of the image is a pair of orange lines indicating directional links to my two KEO relay sats. These have 50Mm directional antennas installed. One antenna always points at KSC (the orange line) and the other antenna will automatically target the "active vessel" which is whatever ship that I am flying at the time.
For example, in this image I have selected the Callisto III satellite that is taking care of those orbital contracts out by the Mun. The green line is the currently active communication path, grey lines are omni-directional antenna links, and the orange lines are directional antenna links.
The trick with directional antennas is that *both* sats have to dedicate a directional antenna to maintaining the link.
Assuming that none of the sats drift out of position, communications are pretty good all the way out to Minimus (the outer moon of Kerbin). Future improvements to the network will be to put even longer range directional antenna units into KEO, but those are further down the tech tree.
New contract details:
This is a pretty easy contract to fulfill as the orbit is outside of KEO but inside of the Mun's orbit. I will still use one of my over-designed Callisto III vehicles to handle it, because after fulfilling the contract I can move the Callisto III out to orbit around the Mun to handle comms within that SoI (sphere of influence).
The Callisto III rockets current cost 23,160 to launch and I'm recovering about 8500 with the Stage Recovery mod for a net cost to orbit one of these 50Mm range comm-sats of about 14.7k. Orbital contracts pay out about 50k (+/- 5k), so I'm making a very nice profit on the launches. Especially if I can manage to service 2-3 contracts with a single launch.
