20.4 Description of the Processing Examples<br />

20.4.1.6 Generate Ionosphere Models and Derive Receiver DCB Values (if desired)<br />

This block allows to determine station specific and regional ionosphere models. The BPEvariable<br />

V F is used as switch, whether or not to perform these steps.<br />

501 PPP_ION PPP_ION ANY 1 321<br />

502 PPPESTAP PPP_ION ANY 1 501<br />

503 PPPEST_P PPP_ION ANY 1 502<br />

504 <strong>GPS</strong>XTR PPP_ION ANY 1 503<br />

511 ADDNEQ2 PPP_ION ANY 1 504<br />

521 <strong>GPS</strong>EST PPP_RIM ANY 1 501<br />

522 <strong>GPS</strong>XTR PPP_RIM ANY 1 521<br />

PID 501 PPP ION: This script either initializes or skips the ionosphere estimation. If parameter<br />

V F is undefined, the scripts responsible for ionosphere estimation are skipped<br />

and PID 901 follows.<br />

PID 502 PPPESTAP: This is the preparatory script for the parallel run of <strong>GPS</strong>EST.<br />

PID 503 PPPEST P: In this <strong>GPS</strong>EST run, station specific ionosphere models are estimated<br />

and saved in <strong>Bernese</strong> ionosphere files (extension ION, in the ATM directory of the<br />

campaign). Receiver P1-P2 DCBs are also computed and stored in station specific<br />

files (extension DCB). In addition the normal equation files are saved for combination<br />

of the receiver specific DCBs (note that all other parameters are pre-eliminated prior<br />

to NEQ saving in this <strong>GPS</strong>EST run).<br />

PID 504 <strong>GPS</strong>XTR: <strong>GPS</strong>XTR creates a summary of the <strong>GPS</strong>EST output from the previous<br />

PID. A summary concerning global ionosphere maps is explicitly requested. The extracts<br />

are listed in the processing summary.<br />

PID 511 ADDNEQ2: ADDNEQ2 combines the contributions from the station specific processing<br />

in PID 503 to the P1-P2 receiver DCB’s. The DCB file additionally appears<br />

in the processing summary.<br />

PID 521 <strong>GPS</strong>EST: In this <strong>GPS</strong>EST run, a regional ionosphere model is generated and stored<br />

in a <strong>Bernese</strong> ionosphere file and in an IONEX file (extension INX). Again, DCBs are<br />

stored, and the file is included in the processing summary.<br />

PID 522 <strong>GPS</strong>XTR: An output summary of the previous <strong>GPS</strong>EST run is produced, which is<br />

included in the processing summary.<br />
