CL_fr_qswMat

Inertial frame to QSW local orbital frame transformation matrix

Calling Sequence

[M] = CL_fr_qswMat(pos_car,vel_car)

Description

Parameters

pos_car:

satellite's position vector relative to the inertial frame [m] (3xN)

vel_car:

satellite's velocity vector relative to the inertial frame [m/s] (3xN)

M :

inertial to QSW local frame transformation matrix (3x3xN)

// Inertial to QSW :
pos_car = [[3500.e3;2500.e3;5800.e3] , [4500.e3;2100.e3;6800.e3]];
vel_car = [[1.e3;3.e3;7.e3] , [2.e3;3.e3;6.e3]];
[M] = CL_fr_qswMat(pos_car,vel_car)
pos_qsw = M*pos_car;

// QSW to inertial :
pos_car = M'*pos_qsw;
