We have used precision Doppler tracking of the Cassini spacecraft during its 2001-2002 solar opposition to derive improved observational limits to an isotropic background of low-frequency gravitational waves. Using the Cassini multilink radio system and an advanced tropospheric calibration system, the effects of heretofore leading noises—plasma and tropospheric scintillation—were, respectively, removed and calibrated to levels lower than other noises. The resulting data were used to construct… 
Constraining the gravitational-wave energy density of the Universe in the range 0.1 Hz to 1 Hz using the Apollo Seismic Array
In this paper, we describe an analysis of Apollo era lunar seismic data that places an upper limit on an isotropic stochastic gravitational-wave background integrated over a year in the frequency
Upper limit on gravitational wave backgrounds at 0.2 Hz with a torsion-bar antenna.
TLDR
This work presents the first upper limit on gravitational wave (GW) backgrounds at an unexplored frequency of 0.2 Hz using a torsion-bar antenna (TOBA) and develops a small-scaled TOBA, which is the first nonintegrated limit to bridge the gap between the LIGO band and the Cassini band.
Low-Frequency Gravitational Wave Searches Using Spacecraft Doppler Tracking
TLDR
