calculating user position satellites

In this project we will be taking a reference point and calculate how many satellites are available to that reference point. We need to give the LLH (latitude longitude height) of the reference point. We will be calculating the Azimuth angle (degrees) and elevation (degrees) of the satellite from the given reference point. We will be plotting the satellites with azimuth angle on X-axis and elevation on Y-axis. Azimuth angle is the angle formed between the reference direction(North) and line formed from the reference point and satellite projected on to the same plane as of the reference direcction
