Abstract

Travel time anomaly in the communicatin of spatial instruments installed in solar planets and Earth are investigated in a model of gravity impact on radio signal propagation. Resulting travel times anomaly shows variations less than 10-3 seconds to and from Venus and Mars while Sun provides anomaly travel times of about -2 × 10-2 sec as backward signal needs more times than emitted signal from Earth. In the current explorations on Mars, the travel time anomaly may reach 1.8 × 10-4 sec as orbital Mars position pass through its minimum distance with respect to Earth. Implications of the difference between one and two-way travel times may be related to redshift/blueshift while travel time of received signal is less or greater than emitted signal.

Highlights

  • In space recording data has been observed such as Pioneer anomaly which may have a gravitational origin [1], and has been explained in term of conformal gravity [2]

  • Travel time anomaly in the communicatin of spatial instruments installed in solar planets and Earth are investigated in a model of gravity impact on radio signal propagation

  • Data from photon travel times inside solar planets are based on initial velocity acquired by photons in a particular planet gravity field

Summary

Introduction

In space recording data has been observed such as Pioneer anomaly which may have a gravitational origin [1], and has been explained in term of conformal gravity [2]. Travel time anomaly in the communicatin of spatial instruments installed in solar planets and Earth are investigated in a model of gravity impact on radio signal propagation. Resulting travel times anomaly shows variations less than 10−3 seconds to and from Venus and Mars while Sun provides anomaly travel times of about −2 × 10−2 sec as backward signal needs more times than emitted signal from Earth.
