Perturbations of existing resonant satellites

摘要: Abstract This paper presents an analysis of the resonant perturbations to 20th degree and order on 83 existing satellites. reveals that terms ( m ) 2 12–14 are well represented by Only a few resonances for other orders available. The phenomenon shallow resonance has also been studied. It is shown accurately analyze orbits, considerable attention calculation mean motion necessary. Highly accurate formulae calculate have derived. study shows orbits with beat periods less than about 15 days, frequencies contributed orbit all nearly same, making such limited value geodesy if considered individually. situation aggravated at or near critical inclination.
