	* '''[[TVM]] (Target Velocity Match)''' uses thrust to match the selected target's velocity plus the commanded closing velocity. Zero commanded closing speed requests a velocity match, not a fixed separation, collision avoidance or automated docking. TVM is separate from ordinary lateral/vertical modes and the DOR transfer planner.		* '''[[TVM]] (Target Velocity Match)''' uses thrust to match the selected target's velocity plus the commanded closing velocity. Zero commanded closing speed requests a velocity match, not a fixed separation, collision avoidance or automated docking. TVM is separate from ordinary lateral/vertical modes and the DOR transfer planner.

			With a ground waypoint selected, TVM allows a controlled descent in a vehicle with suitable vertical thrust. At zero commanded closing speed it damps motion relative to the ground; the actual descent rate depends on the vehicle's mass and available thrust. Monitor vertical speed, height above ground and the landing area. TVM does not command a chosen descent rate, hold a fixed height or fly to the waypoint's position. See [[TVM#Vertical Landings\|TVM vertical landings]].

	*[[Orbit\|DOR]] (Digital Orbital Resolver) provides orbital guidance and control and executes the selected valid plan, including orbit circularization. Ground RENDEZVOUS can plan and fly launch, ascent, insertion and the orbital transfer as one mission, ending with a TVM handoff at the trailing staging point. ~~Standalone ASCENT ends at~~ the ~~parking~~ orbit.

Ground RENDEZVOUS can plan and fly launch, ascent, insertion and the orbital transfer as one mission, ending with a TVM handoff at the trailing staging point. On the ground with an orbital target selected, choose RENDEZVOUS for the whole trip or PARKING ORBIT to stop after insertion. In orbit, ADJUST ORBIT replaces PARKING ORBIT. Ground RENDEZVOUS initially searches for the earliest accepted MEET estimate; you can edit MEET for a later appointment or a different time/fuel tradeoff. See [[Orbit#Ground-to-rendezvous mission\|Ground-to-rendezvous mission]] and [[Orbit]] for operating modes, controls and limitations.
			During DOR atmospheric ascent, ordinary AFCS '''HDG/PIT''' controllers fly the commanded heading and pitch; DOR continues to control thrust. The FMA shows HDG and PIT on those axes. Banked turns replace orbital yaw steering while aerodynamic control is in use. See [[Orbit#Automated ascent alpha\|ascent control and transition limits]]. Selecting another lateral or vertical mode releases DOR and its autopilot engagement, then selects the next ordinary flight-director mode. Re-engage Autoflyte deliberately if wanted. See [[Orbit#Flight path angle (FPA)\|FPA and the current vertical-mode cycle]].
