I was reading up on sun-synchronous orbits on Wikipedia to figure out what altitude I needed for the SpySat mission, and I found out the parameters are entirely based on the oblateness of the planet, and that it's not possible for planets that are too spherical (Kerbin is spherical). For Earth, you'd need an altitude that gives you a 1:7 to 1:16 synchronous orbit, and its inclination is a function of how oblate the planet is. I think the best bet would be to use the examples for Earth. The 1:7 synchronous orbit would be the easiest, but to get within 10 degrees of your target after one day, you'd need to be within 2.5 km of the desired altitude, or less than 1% error. This seems a bit much for a player who hasn't tried a moon landing yet. | I was reading up on sun-synchronous orbits on Wikipedia to figure out what altitude I needed for the SpySat mission, and I found out the parameters are entirely based on the oblateness of the planet, and that it's not possible for planets that are too spherical (Kerbin is spherical).

tl;dr The current article is wrong, it would be impossible in real life, the correct way would be too difficult, and it's kind of silly anyway to make a spy satellite look like a camera so I propose we get rid of this mission. --[[User:Electrollama|Electrollama]] ([[User talk:Electrollama|talk]]) 16:09, 21 August 2015 (UTC) | tl;dr The current article is wrong, it would be impossible in real life, the correct way would be too difficult, and it's kind of silly anyway to make a spy satellite look like a camera so I propose we get rid of this mission. --[[User:Electrollama|Electrollama]] ([[User talk:Electrollama|talk]]) 16:09, 21 August 2015 (UTC) |

## Revision as of 16:10, 21 August 2015

Several missions in this campaign require targeting specific orbital inclinations. Is it possible to see exactly what inclination a vessel is at? Hitting a specific inclination, to two decimal places no less, seems pretty tricky, especially without SAS.

Less specifically, the terminology used definitely ramps up in this campaign (polar orbits, sun synchronous orbits, Molniya orbits, sidereal time). The missions for polar and sun synchronous orbits describe them pretty well, but Molniya orbit and "1/2 sidereal day" are less clear. ~tacocritic (sign talk pages)
