A plot of the differences in successive latitude values of each data set vs the time. Lines between points are drawn to make easy viewing of the spikes.
A plot of the differences in successive latitude values of each data set vs the time. This plot is zoomed in the vertical axis to better show the POS-MV and DGPS data.
A plot of the differences in successive latitude values of each data set vs the time. This plot is zoomed in the vertical axis to better show the POS-MV and DGPS data. It is also zoomed in the horizental axis to show times between 129.2 and 129.3 (decimal day). Also P-Code GPS is plotted with dots and the others lines so the plot is not cluttered, but the trends in the data can be seen.
A plot of the differences in successive latitude values of each data set vs time. Zoomed as in the version 3 and expanded to show times between 129.20 and 129.22
P-Code, DGPS and POS-MV position data measured aboard the R/V Ewing, May 9th, 2002 (Day 129), pierside, Dutch Harbor Alaska.
P-Code, DGPS and POS-MV position data plotted as a funtion of the horizental and vertical distance from each data set's mean and converted to meters. The resulting plot centers the data sets over a single point and clearly shows their relative "tightness".
A histogram of the radial distance from the mean of each data set. The histograms have been normalized for comparison purposes.
A plot of the Horizontal Dilution of Position values vs time for P-Code and DGPS.
A plot of the number of satellites tracked and HDOP values for P-Code and DGPS.
A plot of Horizontal Dilution of Position with P-code longitude and latitude in meters from the Mean.
Successive differences in P-Code Latitude Data.
P-Code position data measured aboard the R/V Ewing, May 9th, 2002 (Day 129), pierside, Dutch Harbor, Alaska.
A plot of the P-Code latitude data vs time.
Successive differences in P-Code longitude data.
A plot of the P-Code longitude data vs time.
A plot of the time intervals between the P-Code data points. This plot shows that a significant number of the data points have roughly a 2 second interval, but that the data is otherwise continuous. See the Data Notes section for more information.
A zoomed plot of the time intervals between P-Code data points showing some interesting details.
A plot of successive averages of P-Code Longtiude. The X axis is the number of points in each average. Ten random starting positions in the data are shown.
A plot of successive averages of P-Code Latiude. The X axis is the number of points in each average. Ten random starting positions in the data are shown.
A plot of the time intervals between the DGPS data points. This plot shows that all the data points have roughly a 2 second interval, but that the data is otherwise continuous. See the Data Notes section for more information.
A zoomed plot of the time intervals between DGPS data points showing some interesting details.
A plot of Horizontal Dilution of Position with DGPS longitude and latitude in meters from the Mean.
A plot of differences in successive DGPS latitude and longitude data taken in 2 second intervals.
An expanded plot of differences in successive DGPS latitude and longitude data.
A further expanded plot of differences in successive DGPS latitude and longitude data.
A plot of DGPS RTCM correction age vs time.
DGPS longitude and latitude and the reported age of RTCM corrections. Longitude and latitude are in meters from the mean. RTCM ages are plotted on an arbitrary scale.
An expanded plot of DGPS longitude and latitude and the reported age of RTCM corrections. Longitude and latitude are in meters from the mean.
A second expanded plot of DGPS longitude and latitude and the reported age of RTCM corrections. Longitude and latitude are in meters from the mean. The plot clearly shows the coorelations between position offsets and RTCM age.
A plot of the differences in successive DGPS longitude positions. Data taken in 2 second intervals.
A plot of the differences in successive DGPS latitude positions. Data taken in 2 second intervals. It's helpful to know that 1 x 10^-5 degrees of latitude ~ 1 5 meters.
A plot of the Horizontal Dilution of Position values and differences in the successive Latitude and Longitude values. DGPS data was taken at 2 second intervals. HDOP values are scaled arbitrarily on this plot.
A plot of DGPS RTCM correction age and differences in successive latitude and longitude positions taken in 2 second intervals.
An expanded plot of DGPS RTCM correction age and differences in successive latitude and longitude positions taken in 2 second intervals.
A second expanded plot of DGPS RTCM correction age and differences in successive latitude and longitude positions taken in 2 second intervals.
A plot of successive averages of DGPS Longitude. The X axis is the number of points in each average. Ten random starting positions in the data are shown.
A plot of successive averages of DGPS Latiude. The X axis is the number of points in each average. Ten random starting positions in the data are shown.
Successive differences in POS-MV Latitude Data.
POS-MV position data measured aboard the R/V Ewing, May 9th, 2002 (Day 129), pierside, Dutch Harbor, Alaska.
A plot of the POS-MV latitude data vs time.
Successive differences in POS-MV longitude data.
A plot of the POS-MV longitude data vs time.
A plot of the time intervals between the POS-MV data points. This plot shows that all of the data points have roughly a 1 second interval, but that the data is otherwise continuous. See the Data Notes section for more information.
A vertically zoomed plot of the time intervals between POS-MV data points showing some interesting details.
A 1 hour stretch of the vertically zoomed plot of time intervals between POS-MV data points showing more interesting details.
