“…The importance of taking into account the influence of radiation pressure on artificial satellite motion does not admit discussion when noting the discrepancies between theories computations and practical observations of balloon-type satellites. The influence that is related to solar radiation pressure exceeds that of drag atmospheric at a height of 800 km and the force equals 10 −5 dyn/cm 2 for an atmospherical model with an exospheric temperature of 1400 k [1].…”

“…Some significant works have been performed to analyze the effect of SRP. Good examples between others are: In [1] the author discussed the effect as one of the non-gravitational force. In [6], the authors analyzed the direct effect of SRP as well as the indirect effect, which is the reflected radiation pressure of Earth or albedo effect on the spherical satellites and those of irregular forms.…”

The aim of the present paper is to analyze the viability of using Lorentz Force (LF) acting on a charged spacecraft to neutralize the effects of Solar Radiation Pressure (SRP) on the longitude of the ascending node and the argument of perigee of the spacecraft’s orbit. In this setting, the Gauss planetary equations for LF and SRP are presented and averaged over the true anomaly. The averaged variations for the longitude of the ascending node (h) and the argument of perigee (g) are invariant under the symmetry (i,g)⟶(−i,−g) due to Lorentz Force. The sum of change rates due to both perturbing forces of LF and SRP is assigned by zero to estimate the charge amount to balance the variation for the argument of perigee and longitude of ascending. Numerical investigations have been developed to show the evolution of the charge quantity for different orbital parameters at both Low Earth and Geosynchronous Orbits.

The inclination I of an Earth's satellite in polar orbit undergoes a secular De Sitter precession of −7.6 milliarcseconds per year for a suitable choice of the initial value of its non-circulating node Ω. The competing long-periodic harmonic rates of change of I due to the even and odd zonal harmonics of the geopotential vanish for either a circular or polar orbit, while no secular rates occur at all. This may open up, in principle, the possibility of measuring the geodesic precession in the weak-field limit with an accurately tracked satellite by improving the current bound of 9 × 10 −4 from Lunar Laser Ranging, which, on the other hand, may be even rather optimistic, by one order of magnitude, or, perhaps, even better. The most insidious competing effects are due to the solid and ocean components of the K 1 tide since their perturbations have nominal huge amplitudes and the same temporal pattern of the De Sitter signature. They vanish for polar orbits. Departures of ≃ 10 −5 − 10 −3 deg from the ideal polar geometry allow to keep the K 1 tidal perturbations to a sufficiently small level. Most of the other gravitational and non-gravitational perturbations vanish for the proposed orbital configuration, while the non-vanishing ones either have different temporal signatures with respect to the De Sitter effect or can be modeled with sufficient accuracy. In order to meet the proposed goal, the measurement accuracy of I should be better than ≃ 35 microarcseconds = 0.034 milliarcseconds over, say, 5 yr.
