Where are the Baseline Results?

Process Summary

The first thing to look at is the process summary since it provides a quick report on your processing.  This summary is always available after processing through Analysis > Process Summary.

For each Baseline occupation, it gives you the following information:

 

 Solution type (Fixed or Float), typically you are looking for a Fixed solution in order to get centimetre accuracy;

 Baseline length (in the selected unit);

 The RMS of the solution;

 The Relative Dilution Of Precision (RDOP since we are in differential mode);

 The ratio of the Fixed solution (typically you are looking for a ratio higher than 3);

 The number of satellite involved in the solution;

 The total number of epochs available;

 The total number of epochs used in the solution;

 The percentage of epochs used in the solution;

Detailed Baseline Report

After processing, each Baseline has its own detailed report which can be access through Analysis > Baseline Results > Baseline Summary.

Site Coordinate Report

You can access a coordinate report through Analysis > Survey Sites > Post-process Coordinates

Baseline Residuals

Advanced users can display and consult observation residuals for each baseline. To view this chart, go through Analysis > Baseline Results > Baseline residuals.  This can be useful to detect problematic data.

It is a complete report that includes the following sections:

 

 Summary

 Base Station (position and general information about the site used as base station in the baseline);

 Remote Station (position and general information about the site used as remote station in the baseline);

 Baseline results (solution type, satellite list, number of epochs, vector components, etc.)

 Covariance matrix;

 Warning section which is a list of any processing problems encountered during vector calculation (satellite without orbits, etc.).

This report offers you information about the reference datum and map projection used to display your coordinates. It also list the known site coordinate along with their standard deviation (standard deviation information is available only after adjustment; see explanations below). The Reference Station reference coordinate used to post-process are also listed in this report.

 

In the example above, notice that there is no standard deviation available for station coordinates. This is simply because the network of vector has not yet been adjusted using the Least-Squares adjustments.  After adjusting (Tools > Process Manual > Adjust Network) the network of vectors, the standard deviation will now be properly displayed.
