Expressed in terms of radii only, the determination of the time of flight along a parabolic trajectory for lunar and planetary flights is shown to be very convenient, especially when ... canonical units. Given the true anomaly and the periapsis distance, the time of flight in a given central force field is readily determined from Barker's Equation. The inverse problem, that ... the numerical accuracy of the solution of the cubic equation for the true anomaly . Here a solution for Barker's Equation, valid for all flight times is presented.
