WebThis discrepancy results from the gravitational blue shift and the second order Doppler Effect. These two effects are different for the satellite and for the observer moving with the Earth’s rotation. The overall effect results in a relative frequency excess of typically 4.7×10-10, which as stated above corresponds to an onboard clock ... WebMay 18, 2024 · blue shift. blue shift In astronomy, an effect in which the lines in the spectrum of a celestial object are displaced towards the blue end of the spectrum. It … The GPS satellite gravitational blueshift velocity equivalent is less than 0.2 m/s, which is negligible compared to the actual Doppler shift resulting from its orbital velocity. In astronomical objects with strong gravitational fields the redshift can be much greater; for example, light from the surface of a white dwarf … See more In physics and general relativity, gravitational redshift (known as Einstein shift in older literature) is the phenomenon that electromagnetic waves or photons travelling out of a gravitational well (seem to) lose See more Astronomical observations A number of experimenters initially claimed to have identified the effect using astronomical measurements, and the effect was considered to have been finally identified in the spectral lines of the star Sirius B See more • Tests of general relativity • Equivalence principle • Gravitational time dilation See more Uniform gravitational field or acceleration Einstein's theory of general relativity incorporates the equivalence principle, which can be stated in various different ways.
