Dynamic Graphs

Dynamic graphs are graphs that update continuously during the filtering process. The following dynamic graph styles are available.

Note: Dynamic graphs are limited to showing the last 2000 points per line.

Satellite Dynamic Graphs of Filter Output
Style Description
Atmosphere Density Estimate Filtered estimate of dRho/Rho compared to +/- 2-sigma error bounds of the estimate.
Ballistic Coefficient Shows the correction of a satellite's ballistic coefficient as the filter runs.
Position Uncertainty Shows, for a satellite, the 2-sigma errors in the radial, intrack and crosstrack position components.
Residual Ratios Enables a unitless test of all residuals computed for a satellite.
Solar Pressure Parameter Estimate Filtered estimate of the correction to the solar pressure parameter compared to +/- 2-sigma error bounds of the estimate.
Velocity Uncertainty Shows, for a satellite, the 2-sigma errors in the radial, intrack and crosstrack velocity components.

Satellite Measurement Residual Graphs

Dynamic graphing styles are provided to show filtered measurement residuals for the following measurement types. Unless noted otherwise, all dynamic measurement residual graphs include +/- 3-sigma bounds and the filtered measurement bias estimates.

GPS Receiver Measurement Residual Graphs

The following table contains descriptions of special cases of measurement residual graphs for GPS receivers.

GPS Receiver Dynamic Graphs of Filter Output
Style Description
2L CA Pseudo Range Residual For a given GPS receiver, 2L CA pseudo-range residuals are shown with 3-sigma error bounds together with the filter estimate for a bias.
Clock Frequency Estimate Filtered estimate of the GPS receiver clock frequency estimate compared to the +/- 2-sigma error bounds of the estimate. Only displayed when clock frequency is a modeled state parameter. (Clock phase and frequency are modeled when "raw" CA, P1 or P2 measurements are processed, and are not modeled when Single Differenced (SD) measurements are processed.)
Clock Phase Estimate Filtered estimate of the GPS receiver clock phase estimate compared to the +/- 2-sigma error bounds of the estimate. Only displayed when clock frequency is a modeled state parameter. (Clock phase and frequency are modeled when "raw" CA, P1 or P2 measurements are processed, and are not modeled when Single Differenced (SD) measurements are processed.)

The following measurement types are available as dynamic residual graphs for a GPS receiver object. Each graph will show the filtered measurement residual, the +/- 3-sigma error bounds, and a bias estimate which can be ignored.

Transponder Dynamic Graphs of Filter Output
Style Description
Transponder Delay Estimate Filtered estimate of the correction to the transponder delay compared to +/- 2-sigma error bounds of the estimate.


Facility Dynamic Graphs of Filter Output
Troposphere Bias Estimate Filtered estimate of the correction to the troposphere delay compared to +/- 2-sigma error bounds of the estimate.

You can select one or more of the above styles in the Dynamic Product Selector. The Simulation Wizard includes a page for selecting dynamic graph styles.
