Method Details

solve

public static Real[] solve(Real[] r1,
 Real[] r2,
 Quantity<Time> dt,
 double mu,
 boolean retrograde)

Solves Lambert's problem using a robust iterative method.

Parameters:

r1 - Position vector at t1 (km)

r2 - Position vector at t2 (km)

dt - Time of flight (seconds)

mu - Standard gravitational parameter (km^3/s^2)

retrograde - Whether the orbit is retrograde

Returns:

Initial velocity vector (km/s)
