AB: It has been demonstrated that high-rate GPS provides useful measurements of seismic waves in cases where seismic instrumentation clips. Even so, intrinsic questions about high-rate GPS remain to be answered. Are there any specific scientific questions that can be answered better with high-rate GPS data than with other instruments? What is the error spectrum of high-rate GPS positions? How degraded are real-time GPS positions relative to the best post-processed positions? Examples from our analysis of high-rate GPS data from recent earthquakes will be discussed, including the impact of modified sidereal filtering and stacking.
