Radio-metric Doppler tracking data received from the Pioneer 10 and 11 spacecraft from
heliocentric distances of 20–70 AU has consistently indicated the presence of a small …

Gravity assist technique plays an important role in deep space missions so that the
interplanetary spacecraft can travel to further space with lower energy. A gravity-assist orbit …

In this paper we analyze the Kerr geometry in the context of Conformal Gravity, an
alternative theory of gravitation, which is a direct extension of General Relativity (GR) …

NEARLY every deep-space mission of the past 30 years has used a gravity-assist
maneuver, or flyby, to achieve low-cost v. Gravity-assists enabled Voyager 1 to depart the …

When tracking objects in space, one must account for the propagation time of light between
the object and the receiver (light-time). Most published tracking algorithms ignore light-time …

This paper presents an improved version of the azimuthally symmetric theory of gravitation
(ASTG) model, which was presented for the first time in the present journal in 2010. I …

An empirical formula recently appeared in the literature to explain the observed anomalies
of about Δ ρ ̇≈ 1-10 mm s− 1 in the geocentric range-rates ρ ̇ of the Galileo, NEAR and …
