<Aitor Jua> how can I do a principia manouver with srb?
<queqiao-->
<Aitor Jua> ??

<Nazfib> - Use "instant impulse" in the planner, and set it to the actual Δv of the SRB — MJ underestimates it significantly, try it in a sim a few times to see how much you actually get on average. - Start the SRB a few seconds before T=0 on Principia's timer — ideally, you want half the Δv to be expended before the T=0 point and half after. Half the burn time before/after might be close enough. - (Optional) Trim the final orbit
<queqiao-->
with RCS after your manoeuvre — due to unavoidable small misalignments in your burn direction, and variance in the SRB's total Δv output, the results will always be inaccurate to some degree. RCS or small liquid engines can be used to clean up afterwards.

<Aitor Jua> what upgrades do I need for making manouvers?

<RD-301 worshipper> I think tracking station and Mission Control upgrades.
<queqiao-->
<RD-301 worshipper> iirc the Mission Control upgrade will allow you to display the maneuver node on the navball.

<RD-301 worshipper> At least I’m pretty sure
