Unified Formula for Comparison of Clock Rates and Its Applicationsa perturbed Robertson–Walker metric, our formula returns to an equation for the comparison of clock rates at different cosmic space–time points, which includes the Hubble redshift, the Doppler effect, the gravitational redshift, and the Rees–Sciama effects. In the case of the solar system, when the

Measurement of the Shapiro Time Delay Between Drag-Free Spacecraft body such as the Sun. The delay for two-way measurements from Earth to a spacecraft passing behind the Sun can be more than 200 μs. Microwave range and rangerate measurements of this kind from Earth to several spacecraft have provided our best information so far on .. Laser time-delay measurements

Laser Transponders for High-Accuracy Interplanetary Laser Ranging and Time Transfer. The single-ended SLR ranging technique, although capable of providing millimeter precision range data to satellites, is not practical over interplanetary ranges. Double-ended laser transponders for decimeter or better accuracy interplanetary ranging and subnanosecond time transfer are well within

Clocks and Accelerometers for Space Tests of Fundamental Physicscs in space. By developing instruments that can serve multiple functions, we hope to gain flight opportunities that would otherwise be unavailable, due to recent refocusing of the space science mission in support of manned flights. We discuss the development of a liter-sized clock based on trapped m
