Does the Earth's spin impact time dilation for satellites and GPS receivers?

Is it plausable to take into account the speed of the Earth's spin when calculating tmie dilation for satellites and GPS receivers?

You could take into account the satellites spining against the Earth's orbit, with the Earth's orbit and at an angle?

I put it into my project but is it a good idea or am I missing something to do this? I found that for a recevier on the equator and a satellite goin with the orbit the difference to be
9.3 *10^-6 (without relative velocity the answer is 7.3 *10^-6)

can anyone tell me if what I am doing holds for anything?
 

Thread 'A sufficient condition for integrability of equation ##\nabla g=0##'

In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...

Thread 'Can this experiment break Lorentz symmetry?'

1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
