A new global empirical model of relative ion composition for the O+, H+, He+, and N+ ions in the altitude range of 500 to 2500 km was proposed using the ACTIVE mission data for solar maximum and the Atmospheric Explorers data for solar minimum. Relative ion density obeying first order influences has been approximated at fixed altitude ranges by a system of associated Legendre polynomials. To obtain vertical profiles, interpolation based on Booker formalism is employed. This model is compared with available mass spectrometers data measured onboard the mentioned and several other satellites.
