22. Data Structure<br />

22.4.2 Geodetic Datum Information<br />

Type: ASCII<br />

Directory: ${X}/GEN (UNIX) or %X%\GEN (Windows)<br />

Extension: -<br />

Content: Information concerning different geodetic datum definitions to transform geocentric<br />

cartesian coordinates into ellipsoidal coordinates.<br />

Created by: User-defined. Available from BSW aftp server.<br />

Used by: All programs accessing coordinate files. RXNPRE (”Menu>RINEX>Import RINEX to<br />

<strong>Bernese</strong> format>Navigation files to SP3”) for conversion of PZ-90 into ITRF.<br />

Example: Figure 22.3 and${X}/GEN/DATUM..<br />

Users may add more geodetic data. Each coordinate file refers to one of the datums specified<br />

in this list. The datum information is only used to compute ellipsoidal coordinates of the<br />

sites and has no influence on the estimated coordinates. The entry for PZ-90 is required to<br />

transform GLONASS broadcast information into ITRF in program RXNPRE.<br />
