'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 priori 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 priori model based Tropospheric delay estimation.</li><li>Specify a Noise to describe the expected variation of the tropospheric effect over time.
