SEC GPS Three-Dimensional Position Variation Data Plots

GPS Three-Dimensional Position Variation 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. Position determinations are obtained once per minute and the variation from the average position is plotted. For more information about the complete data sets, please contact Dr. Vince Eccles.

Current data plots are also available.

Changes in data quality:

The Cornell GPS software was updated on 13 March 2001, providing these position data in addition to the S4 dataset.
A new, larger ground plane was installed on 13 April, producing disturbances from about 1645-1930 UT.
A 3 dB attenuator was added on 17 May at about 1730 UT to try to reduce multipath interference.
The attenuator was replaced with a 6 dB unit on 5 June at 1630 UT.
The Cornell software was updated June 19-20 with Cascade 0.98/RTLinux-3.0 (downtime approximately one day) and the attenuator was removed.
The Cornell software was updated August 14 1828 UT with Cascade 1.10 to correct data dropout problems.
The Cornell software was updated October 19 1745 UT with Cascade 1.20; spike can be seen in data following restart.
