List and meaning of the constants which are used for calculation.

Conversion of geocentric coordinates into geodesic coordinates:
- ellipsoid semi-major axis: $6378137, m$ ;
- ellipsoid semi-minor axis: $6356752.314245, m$ .
Calculation of elevation and azimuth:
- Earth’s radius: $6371 \cdot 10^3, m$ .
Calculation of geocentric coordinates of the GPS, GLONASS and GEO satellites:
- Earth’s angular velocity: $7.2921151467 \cdot 10^{-5}, rad/s$ ;
- Earth’s gravitational field constant: $39860044 \cdot 10^7, m^3/s^2$ ;
- second zonal harmonic of geopotential expansion into a series of spherical functions: $1082625.7 \cdot 10^{-9}$ ;
- ellipsoid semi-major axis: $6378136, m$ (for GLONASS, according to PZ-90).
