LISA Data Reduction
The passage of graviational waves changes the arm lengths between corners of the LISA spacecraft formation. These changes are detected interferometrically and recorded as phase measurements. The time series are reduced to reveal several signal types.

Thermal Stability Analysis for a Heliocentric Gravitational Radiation Detection Mission
The Laser Interferometer Space Antenna (LISA) mission is designed for detailed studies of low-frequency gravitational radiation. The mission is currently a candidate for ESA's post-Horizon 2000 program. Thermal noise affects the measurement in at least two ways. Thermal variation of the length of the optical cavity to which the lasers are stabilized introduces phase variations in the interferometer signal, which have to be corrected for by using data from the two arms separately.

Tracking Galileo at EArth-2 Perigee Using The Tracking and Data Relay Satellite System
The tracking and Data Relay Satellite System (TDRS) was successfully used to track the Galielo spacecraft on December 8, 1992, during the Galielo Earth-2 flyby. This flyby enabled Galielo to obtaina gravity assited energy increase as part of the Venus-Earth-Earth trajectory en route to the planet Jupiter.

Very-Long-Baseline-Interferometry Measurements of Planetary Orbiters at Mars and Venus
Very-long-baseline interferometric measurements of the positions of planetary orbiters/landers relative to nearby extra galactic radio sources provide information on the positions of the planets in the inertial reference frame described by the measured positions of the radio sources.
