Probing Lorentz andCPTviolation with space-based experiments

Space-based experiments offer sensitivity to numerous unmeasured effects involving Lorentz and $\mathrm{CPT}$ violation. We provide a classification of clock sensitivities and present explicit expressions for time variations arising in such experiments from nonzero coefficients in the Lorentz- and $\mathrm{CPT}$-violating Standard-Model Extension.
