| CurrentManeuver | The current maneuver state of the RPO software. |
| DecreasePhaseOrbitFactor | The factor between the true anomalies of the target and chaser orbits fromwhich, if the chaser is ahead, it will decrease its orbit to match the target’sorbit instead of increasing it. |
| In_EphemerisMsg | Chaser’s ephemeris: position and velocity in inertial frame. |
| In_OrbitalMsg | Chaser’s orbital elements. |
| In_PlanetStateMsg | Planet state: position, velocity, and gravitational parameter. |
| In_TargetEphemerisMsg | Target’s ephemeris: position and velocity in inertial frame. |
| In_TargetOrbitalMsg | Target’s orbital elements. |
| IsPhaseAhead | The state of whether the chaser is ahead of the target in the orbit during thephase change maneuver. This is used to determine whether the chaser should beincreasing or decreasing its orbit to match the target’s orbit. |
| MatchingAscensionDelta | Represents the minimum right ascension of the ascending node (RAAN) deltaduring the Plane Change stage of the maneuver. |
| MatchingInclinationDelta | Represents the minimum inclination delta used for matching the orbits duringthe Plane Change stage of the maneuver. |
| MatchingPerigeeDelta | Represents the argument of perigee delta used for matching the orbits duringthe Hohmann stage of the maneuver. |
| MatchingPeriodDelta | Represents the time interval, in seconds, used for matching periods at the endof the phase change maneuver. |
| MatchingRadiusDelta | Represents the radius delta used for matching the orbits during the Hohmannstage of the maneuver. |
| NearPlaneNode | The angle in degrees near the nodal line where the chaser should fire itsthrusters at for aligning the plane change maneuver. The larger this valueis, the less precise the maneuver will be, but it will also be faster. |
| Out_AttitudeReferenceMsg | Attitude reference: desired pointing in inertial frame. |
| Out_RendezvousManeuverMsg | The rendezvous maneuver message that contains the maneuver details. |
| Out_ThrusterBurnMsg | Thruster burn command: delta velocity and thrust direction. |
| PerformedPhaseBurn | A flag indicating whether the first phase change maneuver has been performed andthat the chaser is now in the second phase change maneuver. This applies to thephase change maneuver where the chaser will match the target’s orbit. |
| RequiredPhasePeriod | The period of the target orbit that the chaser should match during the phasechange maneuver. |
| ThrustDirection_N | The current thrust direction for the thruster burn. |
| ThrustFactor | A factor to apply on the thrust force to scale it, in the directionof the thrust. This is useful for simulating different thrust levels. |
