This oral presentation discusses spacecraft Doppler tracking in which Doppler data recorded on the ground are linearly combined with Doppler measurements made on board a spacecraft. Methods are proposed to remove or reduce frequency fluctuations from the data that are caused by multiple circumstances. The resultant data from these proposed methods may have applicability in testing relativity theory.
Spacecraft Doppler tracking is discussed for detecting gravitational waves in which Doppler data recorded on the ground are linearly combined with Doppler measurements made on board a spacecraft. A new method is derived for removing from combined data the frequency fluctuations due to the Earth troposphere, ionosphere, and mechanical vibrations of the antenna on the ground. The remaining non-zero gravitational wave signal could be used for detecting gravitational waves.
This paper presents the interferometric detection of gravitational waves using multiple bounce parallel-beam systems. Results show it is possible to remove laser frequency fluctuations from an offset paralllel-beam interferometer without removing the gravitational wave signal.
In hetrodyne laser tracking of a spacecraft, the incoming laser signal may be significantly offset from the local laser reference, producing a high-frequency beat note that must be accurately counted to produce an accurate phase measurement.
It is possible that a gravitational wave background, analogous to the electromagnetic one, fills the whole Universe.
