Contribution

It provides an analysis of the gravitomagnetic clock effect and proposes a mission scenario to observe this phenomenon using orbiting clocks.

Findings

Clocks exhibit a measurable time difference due to gravitomagnetism.

Detection of Earth's gravitomagnetic field is feasible with precise orbiting clocks.

Identifies major challenges in implementing such a measurement.

Abstract

As a consequence of gravitomagnetism, which is a fundamental weak-field prediction of general relativity and ubiquitous in gravitational phenomena, clocks show a difference in their proper periods when moving along identical orbits in opposite directions about a spinning mass. This time shift is induced by the rotation of the source and may be used to verify the existence of the terrestrial gravitomagnetic field by means of orbiting clocks. A possible mission scenario is outlined with emphasis given to some of the major difficulties which inevitably arise in connection with such a venture.
