Figure 22.41: Station observation sigma factor (SOS) file.<br />

This file provides station observation sigma factors for a list of stations and for specific<br />

measurement types. The factors may be used by program CODSPP for the scaling of the<br />

outlier rejection threshold, see Section 6.3.2. Program <strong>GPS</strong>EST may make use of the observation<br />

sigma factors for applying a station-specific weighting of the observations or for a<br />

rescaling of the edit level for code observations in the zero-difference mode, see Section 7.4.2.<br />

In particular, weighting of observations may be useful for pseudorange observations. Station<br />

observation sigma factors may be determined with program RESRMS based on residual<br />

statistics, see Section 6.6.<br />

The end of the station observation sigma factor file is indicated by a blank line. Lines below<br />

the blank line are ignored.<br />

22.8.15 Baseline Definition File<br />

Type: ASCII<br />

Directory: Campaign-specific directory STA.<br />

Extension: BSL<br />

Content: Pre-defined baselines.<br />

Created by: User-defined. Assistance using ”Menu>Campaign>Edit station files>Baseline list”, or<br />

written by SNGDIF (”Menu>Processing>Baseline file creation”) or MPRXTR (”Menu<br />

>Processing>Program output extraction>Phase preprocessing”).<br />

Used by: SNGDIF and COMPAR (”Menu>Service>Coordinate tools>Coordinate comparison”).<br />

Example: Figure 22.42 and ${X}/DOC/EXAMPLE.BSL.<br />

The baseline definition file may be used in the following cases:<br />

(1) Pre-define baselines in the program SNGDIF.<br />

This option is useful to force program SNGDIF to form specific baselines (e.g., baselines<br />

with identical antenna types) independently of the strategy used. Possible strategies<br />

are explained in Section 6.4. It is in addition possible to store the baseline definitions<br />
