Site Survey
Observe and compute using ‘least squares’ software a mixed traditional control network linked to the national grid using traditional survey methods (angle and distance);
Analyse this network to produce standard errors and error ellipses for the unknowns; Simulate, locate and estimate a gross error using analytical output;
Carry out a differential GNSS survey covering the above network (through post processing of the observed data);
Obtain the GNSS OSGB co-ordinates and compare your results with the ‘least squares’ results of the traditional method;
Re-compute and analyse the network to include the GNSS observations.
