The frequencies of a cryogenic sapphire oscillator and a hydrogen maser are compared to set new constraints on a possible violation of Lorentz invariance. We give a detailed description of microwave resonators operating in Whispering Gallery modes and then apply it to derive explicit models for Lorentz violating effects in our experiment. Models are calculated in the theoretical framework of Robertson, Mansouri and Sexl (RMS) and in the standard model extension (SME) of Kostelecky and co… 
Test of Lorentz invariance in electrodynamics using rotating cryogenic sapphire microwave oscillators.
TLDR
The experiment is used to test for violations of Lorentz invariance in the framework of the photon sector of the standard model extension (SME), as well as the isotropy term of the Robertson-Mansouri-Sexl (RMS) framework.

Cryogenic sapphire oscillators (CSO) developed at UWA have now been in operation around the world continuously for many years. Such oscillators are essential for interrogating atomic frequency
Long-term operation and performance of cryogenic sapphire oscillators
TLDR
The long-term drift rates turn out to be linear over many years and in the same direction, but the magnitude seems to vary by more than one order of magnitude between the oscillators, ranging from 1014 per day to a few parts in 1013 per day.

Tests of Lorentz invariance using a microwave resonator.
TLDR
The frequencies of a cryogenic sapphire oscillator and a hydrogen maser are compared to set new constraints on a possible violation of Lorentz invariance and determine the variation of the oscillator frequency as a function of its orientation and of its velocity with respect to a preferred frame candidate.
