The Use of Resonant Orbits in Satellite Geodesy: A Review

摘要: Dynamic resonance, arising from commensurate (orbital or rotational) periods of satellites planets with each other, has been a strong force in the development solar system. The repetition conditions over can result amplified long-term changes positions bodies involved. Such resonant phenomena driven by commensurability between mean motion certain artificial Earth and Earth’s rotation originally contributed to evaluation assessment Stokes parameters (harmonic geopotential coefficients) that specify gravitational field. technique constrains linear combinations harmonic coefficients are relevant order (lumped coefficients). attraction method eventually dwindled, but very accurate orbits CHAMP GRACE have recently led more general insights for applied satellite geodesy involving best resolution all coefficients, not just ones. From mission, we learnt how explain predict temporary decreases accuracy derived parameters, due passages through low-order commensurabilities, which lead low-density ground-track patterns. For GOCE suggest change repeat orbit height slightly, achieve feasible recovery field on-board gradiometric measurements direct inversion way lumped coefficients. orbiters Mars, suggestions should be avoided. slow Venus results dense ground-tracks excellent almost orbiters.
