For the complete documentation index, see llms.txt.Orbit Raise plans a low-thrust transfer that raises a spacecraft from its current orbit to a higher circular target altitude. The platform always computes two options for the same target — a Min-fuel option and a Fastest option — so you can weigh propellant against time before committing. You review both side by side and approve the one you want; the approved option becomes a normal maneuver plan in the existing approval and execution lifecycle. This page documents the Orbit-Raise-specific configuration and the two-option comparison. For the shared wizard steps (Overview, Initial State, Time Range, Review) and general Planner functionality, see the Planner overview. Route:
/maneuvers/planner
Creating a raise
In the Planner, click New Plan, and on the Overview step choose Orbit Raise as the Maneuver Type. The wizard’s five steps are the same as every other plan (Overview, Initial State, Time Range, Parameters, Review); only the Parameters step is Orbit-Raise-specific, and there is no option picker — both options are always computed.- On Initial State, the raise starts from the spacecraft’s latest computed state vector, or you can select a different state vector or initialize from the latest public TLE — exactly as for other plans.
- On Time Range, set the window (in UTC) within which the raise may run.
Step 4: Orbit Raise Parameters
Configure the circular target the raise should reach and the propellant it is allowed to spend.
The Max fuel to be used value is a cap on the whole raise. It defaults to the full available propellant and cannot exceed it — if you lower it, both options are still computed, but a computed option is only approvable when it fits within the cap (see Approving a raise).
When you reach Review and click Create Plan, the raise launches and appears as a single plan in Evaluation while its two options are computed.
Comparing the two options
Once both options are ready, the plan detail shows them side by side as an equal-weight Min-fuel / Fastest selector. Each option lists the same figures so you can compare them directly:
Select the option you prefer — the selected option is emphasized — and a single primary Approve action (for example, Approve Min-fuel) commits it.
While the two options are still computing, each shows its own progress (Queued, then Computing), and each settles to Ready or Failed independently — if one option fails, the other stays usable. Full velocity-change (Delta-V) figures appear on the approved plan’s Plan details once you approve an option.
When the two options coincide
For some raises the min-fuel and fastest solutions are the same. In that case the detail shows a single plan with a plain note that Min-fuel and Fastest coincide for this raise, and you approve that one plan — there is no separate comparison to make.Approving a raise
Approving an option turns it into a definitive maneuver plan and moves it into the existing lifecycle as Approved, exactly like any other plan. From there the standard Approve / Reject / Delete / Export actions and Plan details apply, and the option you did not approve is discarded. Approval runs a final propellant check. If the option you approve would spend more than the cap, or the propellant use cannot be validated, the raise is not saved and an inline message explains why:When a raise can’t reach the target
If neither option can reach the target — for example, the window is too short or there is not enough propellant — the detail does not show a plan with a disabled Approve. Instead it shows a plain message that the target Can’t reach this target, naming the limit that blocks it (propellant or time) and telling you to modify the target, window, or max fuel and try again. The panel offers two actions:- Modify — reopens the New-plan dialog so you can adjust the target, window, or Max fuel to be used.
- Discard — dismisses the raise.
Eligibility
Some spacecraft cannot be raised — for example, one with no propulsion configured, or more than one thruster. When you configure a raise for such a spacecraft, the dialog shows an inline message that This spacecraft can’t be raised yet, lists the specific reason(s), and blocks Create Plan until they are resolved.Related Pages
