“…Shapiro 1964). An estimate of γ from the effective delay on radio range measurements to the Viking landers during the solar conjunction of 1976 was given with an uncertainty of 0.002 by Reasenberg et al (1979). From the radio range measurements from the Viking landers during the solar conjunctions of 1976 and 1979, combined with radio range and VLBI measurements from later orbiting spacecraft not during conjunction, we find that (γ − 1) = 0.00009 ± 0.00070.…”

Abstract. The orbits of the planets as represented by the JPL planetary ephemerides are now primarily determined by radio tracking of spacecraft. Analysis of the data and propagation of the orbits relies on an internally consistent set of equations of motion and propagation of radio signals including relativistic effects at the centimeter level. The planetary ephemeris data set can be used to test some aspects of the underlying theory such as estimates of PPN parameters γ and β, time variation in the gravitational constant G, rotation of the solar system relative to distant objects (Mach's principle), and place stringent limits on the possible violation of the inverse-square law.

“…Since ϕ varies on a cosmological time scale, it is appropriate to approximate ϕ with its present value ϕ 0 and ω (ϕ) ≃ ω (ϕ 0 ) ≡ ω 0 . The lower bound on ω 0 is 1 |ω 0 | > 500 [29,30], which yields…”

Indication, from Pioneer 10/11, Galileo, and Ulysses Data, of an Apparent Anomalous, Weak, Long-Range Acceleration

et al. 1998

Radio metric data from the Pioneer 10/11, Galileo, and Ulysses spacecraft indicate an apparent anomalous, constant, acceleration acting on the spacecraft with a magnitude ∼ 8.5 × 10 −8 cm/s 2 , directed towards the Sun. Two independent codes and physical strategies have been used to analyze the data. A number of potential causes have been ruled out. We discuss future kinematic tests and possible origins of the signal.
