Rates of change of Euler angles to angular velocity of a rotating coordinate system

I am trying to implement the conversion between TEME and GCRF frames following the same procedure as done in SPICE. After digging into CSPICE's code, this transformation is performed through the ...

How can I determine a rotation matrix from unit vectors?

I want to determine the rotation matrix from which compute the Euler Angles to rotate my spacecraft in order to point in a specific direction. For example, i want the z body axis of the spacecraft to ...

Determine Yaw, Pitch, Roll from two vectors

I need to find the roll, pitch an yaw rotation to point a satellite to a precise point on Earth. I know the satellite position and velocity in ECEF coordinates, the position of the site on Earth (also ...

Satellite's EO sensor footprint on ground

I'm a student and I'm trying to compute the footprint of a generic EO sensor starting from sensor's characteristics and position and velocity vector of my satellite in ECEF coordinates. I followed ...

Rotation matrix / coordinate transformation of maneuver parameters from Prograde, Normal, Radial to Cartesian XYZ?

Say I have a state vector and Keplerian elements of an orbiting spacecraft: Position = [x, y, z] Velocity = [vx, vy, vz] Elements = [a, e, i, $\omega$, $\Omega$, $\nu$] And I have the maneuver I ...

Converting J2000 to ECEF?

Say I get the orbital elements for the ISS from JPL Horizons. Say that data is expressed in J2000, an inertial frame. I want to express it in ECEF. This is a simple rotation transform. All I need is ...
