SKYPLOT for a given receiver position Y=skyplot(X,PRN,C,O) draws the skyplot for the receiver position. The required inputdata for the calculation of the skyplot X is N-by-3*M matrix, where N are the timesteps and M is the number of the Sat

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
