Adjustment functionality in High Rise

The adjustment functionality is most important in a deformation analysis environment. Use it to perform a least squares adjustment of your network of processed baselines. The purpose of the adjustment is to:

• detect blunders and large errors,
• generate information for analysis, including estimates of precision values (D Northing, D Easting, D Height, D 2D, and D 3D), as well as the respective 3-s values),
• minimize corrections made to the observations.

After a least squares adjustment is successfully performed, you can determine that:

• there are no blunders and systematic errors in the observations,
• any remaining errors are small, random, and properly distributed.

A least squares adjustment ensures good positional closures and estimates of repeatability; thus, it ensures the reliability of your current and future measurements.

To complete a successful adjustment with GNSS data, a least squares network must meet these criteria:

• The network must close geometrically and mathematically.
• The sum of the weighted squares of the residuals must be minimized.

Numerical results of the adjustment are the following:

• Residuals moved to not fixed stations,
• Conversion of vectors to a set of position coordinates.

The functionality is comparable to a fully constrained adjustment; once the network is fixed to the control stations, adjusted coordinates for all other stations in the network can be determined.
