(abstract) GPS Monitoring of Crustal Deformation and the Earthquake Cycle in Costa Rica
This paper will discuss the objectives, approach, and anticipated results of a study of earthquakes in Costa Rica. GPS measurements will be taken and field surveys will be made. Assessments of seismic strain accumulation and post-seismic deformation will be made in an effort to understand the effect these processes have on regional tectonic models.

Gravity deformation measurements of 70m reflector surfaces
Two of NASA's Deep Space Network (DSN) 70-meter reflectors are measured using a Leica TDM-5000 theodolite. The main reflector surface was measured at five elevation angles so that a gravity deformation model could be derived that described the main reflector distortions over the entire range of elevation angles. The report describes the measurement equipment and accuracy and the results derived from the data.
