Fixing a priori coordinates is done in BNC through setting 'Sigma N/E/H' temporarily to zero.</p><p>This option allows the PPP solution to rapidly converge. It requires that the antenna remains unmoved on the a priori known position throughout the startup period.</p><p>A value of 60 is likely to be an appropriate choice.</p><p>Default is an empty option field, meaning that you don't want BNC to fix PPP solutions during startup to an a priori coordinate.</p>"));
