CL_oe_kep2car

Description

• Converts classical Keplerian orbital elements to cartesian orbital elements.

  The transformation jacobian is optionally computed.

  See Orbital elements for more details.

Parameters

kep:

Classical Keplerian orbital elements [sma;e;inc;pom;raan;M] [m,rad] (6xN)

mu :

(optional) Gravitational constant. [m^3/s^2] (default value is %CL_mu)

pos:

position [X;Y;Z] [m] (3xN)

vel:

velocity [Vx;Vy;Vz] [m/s] (3xN)

jacob:

(optional) Transformation jacobian (See Orbital elements for more details) (6x6xN)

Examples

// // Example 1 kep = [7000.e3; 1e-4; 1e-4; 1; 2; %pi/2]; [pos,vel] = CL_oe_kep2car(kep); // Example 2 kep = [7000.e3; 1e-4; 1e-4; 1; 2; %pi/2]; [pos,vel,jacob1] = CL_oe_kep2car(kep); [kep2,jacob2] = CL_oe_car2kep(pos,vel); kep2 - kep // zero jacob2 * jacob1 // identity
