OrbitalElementsConvertMeanAnomalyToTimeFromPeriapsis Method

Converts the mean anomaly to the time of flight from the corresponding periapsis passage in seconds. The value returned is signed and monotonic even for periodic orbits.

Namespace:  AGI.Foundation.Coordinates
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 25.1.421.0 (25.1.421.0)
Syntax
