ELEVAT calculation for elevation, zenit angle and spatial distance

e_az_s=elevat(D,RHO) computes the elevation, the zenit angle and the

spatial distance between a satellite(j) and a receiver(i). The receiver

position (D) is a 3-by-3 matrix [n e u] and the distance between the

sv and rx (RHO=X(j)-X(i)) is a N-by-3 vector with N satellite postitions

calculated from spatial coordinates in m.

The output e_az_s is a N-by-3 vector and contains the elevation angle [°],

the zenit angle [°] and the spatial distance [m] from the rx to the sv.- ELEVAT calculation for elevation, zenit angle and spatial distance
