AscentGT

type krpc_MechJeb_AscentGT_t

This profile is similar to the gravity turn mod. It is a 3-burn to orbit style of launch that can get to orbit with about 2800 dV on stock Kerbin. If you want to have fun make a rocket that is basically a nose cone, a jumbo-64 a mainsail and some fairly big fins, have the pitch program flip it over aggressively (uncheck the AoA limiter, set the values to like 0.5 / 50 / 40 / 45 / 1) and let it rip.

Note

It’s not precisely the GT mod algorithm and it does not do any pitch-up during the intermediate burn right now, so it won’t handle low TWR upper stages.

krpc_error_t krpc_MechJeb_AscentGT_HoldAPTime(krpc_connection_t connection, double *result)

void krpc_MechJeb_AscentGT_set_HoldAPTime(double value)

At the intermediate altitude with this much time-to-apoapsis left the engine will start burning prograde to lift the apoapsis. The engine will throttle down in order to burn closer to the apoapsis. This is very similar to the lead-time of a maneuver node in concept, but with throttling down in the case where the player has initiated the burn too early (the corollary is that if you see lots of throttling down at the start, you likely need less HoldAP time).
