For the following question, I just want to know what frame is the Jacobian matrix in. I derived the J matrix. Lets assume that I used the state vector of the ISS. Does that mean that the J matrix is in ECI frame? Since the question asked to ignore precession, nutation, and polar motion, I assume we are not in J2000. The question also says use explicitly the earth-fixed station vector R, but I think I used that to find the mapping matrix H. Compute analytically the Jacobian of the two-body motion and the measurement mappingmatrix H when measuring topocentric right ascension and declination of a satellite. Useexplicitly the earth-fixed station vector R, and the state of the satellite (position and velocity).You may neglect precession, nutation and polar motion. You may assume light travel time,aberration and refraction has already been corrected for. Show intermediate steps.
