UmbralRaptor: so the thing is, you can't really render hieroglyphic texts properly with just Unicode right now (and if you start peppering it with CSS it gets nuts)
<egg|work|egg>
UmbralRaptor: individual hieroglyphs otoh should refer to the codepoint, definitely
<egg|work|egg>
UmbralRaptor: otoh, you should absolutely stab people who use jpgs or gifs or latin mappings for cuneiform instead of Unicode...

Hi!
<APlayer>
Unrelated to my problem from a few days ago (simulating low thrust vehicles), does anyone here know of any papers on rocket guidance algorithms for orbital launches? There are plenty on the internet, but all I found so far seem to cost money to access.
<Iskierka>
"Powered explicit guidance" "linear rocket guidance" aaand I forget what the russians called it. Poke Black_Phoenix
<Iskierka>
Also forget what the name for the shuttle version was
<Iskierka>
but he'll know
<APlayer>
Iskierka: You once pointed me at the three search terms "powered explicit guidance", "unified powered flight guidance" and "rocket linear guidance", and I've looked through the first Google search result pages for each of them
<APlayer>
I may of course have missed something, but it seems there are less papers than anticipated
<APlayer>
That I could access*
<Iskierka>
UPFG is the shuttle one for sure
<Iskierka>
for the first two look at NASA stuff since that's who made them
<APlayer>
Wow, thanks! Though I am not sure I can read the formulas, it's a bit... Well, grainy or something
<Iskierka>
readable if you know what kind of form the formulae should be but that might be a limiting factor
<Iskierka>
is actually just a guidance method that can take you from any position & velocity to a position & velocity requested in the least time, so requires tweaking depending on uses but can be used for almost all rocket burns, including ejection to other planets, if you can define the desired exit conditions
<Iskierka>
although for super-long burns like ions where you don't have atmosphere limitations it's probably better to do an integral of prograde thrusting; it can develop problems in very long burns with trying to get to the right altitude. Better to simplify and just control the velocity
