	Prediction	Easily applicable in practice?
From redshift and orbital velocity	$c = \frac{\sqrt{2 λ_{h}^{2} v_{o, L}^{2} - 2 λ_{L}^{2} v_{o, h}^{2}}}{\sqrt{λ_{h}^{2} - λ_{L}^{2}}}$	Easy enough
From redshift and acceleration field	$c = \frac{\sqrt{2 λ_{h}^{2} g_{L} R_{L} - 2 λ_{L}^{2} g_{h} R_{h}}}{\sqrt{λ_{h}^{2} - λ_{L}^{2}}}$	Easy enough
Atomic clocks + orbital velocity	$c = \frac{\sqrt{2 v_{o, L}^{2} T_{h}^{2} - 2 v_{o, h}^{2} T_{L}^{2}}}{\sqrt{T_{h}^{2} - T_{L}^{2}}}$	Does not take rotation of Earth into account
