this code is an navigation ephemeries reader for GNSS systems like GPS, GLONASS, BeiDou and Galileo

this code is written for GPS satellites almanac and the steps is as follows:

• 1- reading navigation rinex file
• 2- compute kepler parameters
• 3- compute ECEF coordinate of satellites
• 4- plot ground track of satellites
• 5- plot sky plot of satellites for a known point in earth

It use WGS84 as the ellipsoid reference
