Specify also a Sigma in meters for a-priory model based Tropospheric delays and for the delay's Noise in meters per second.</p><p>'Sigma' is meant to describe the uncertainty of a single coordinate or tropospheric delay estimated for one epoch. 'Noise' is meant to describe the variation of estimates from epoch to epoch.</p><p><ul><li>A Sigma of 100.0 meters may be an appropriate choice e.g. for the initial N/E/H coordinates. However, this value may be significantly smaller (i.e. 0.01) for stations with well known a-priory coordinates.</li><li>A Noise of 100.0 meters for the estimated N/E/H coordinates may also be appropriate considering the potential movement of a rover position.</li><li>A value of 0.1 meters may be an appropriate Sigma for the a-priory model based Tropospheric delay estimation.</li><li>Specify a Noise to describe the expected variation of the tropospheric effect over time. Supposing 1Hz observation data, specifying a value of 3e-6 would mean that the tropospheric effect may vary for 3600 * 3e-6 = 0.01 meters per hour.</li></ul></p>"));
