GPS S4 Filtered Data Summary Plots for 2001

The following summary plots have been generated from data collected by the Space Environment Corporation GPS S4 instrument at the Utah State University Bear Lake Observatory. This instrument uses a GPS card and software called Cascade developed at Cornell University. The scintillations measured by this instrument are not particularly pronounced in mid-latitudes; the equipment is running at Bear Lake to test the hardware and software interfaces. For more information about the complete data sets, please contact Dr. Vince Eccles.

These plots have points near the horizon removed using a horizon mask. These low-elevation points show false scintillations due to multipath reflections from hills to the south and west of BLO. Unfiltered data plots are available.

Current data plots are also available.
