20.4.1.1 Copy Required Files<br />

20.4 Description of the Processing Examples<br />

Prior to starting any processing program, all necessary files must be made available for the<br />

BPE in specific directories. This is accomplished by this first PCF section. Usually, all PCFs<br />

begin with such a copy script to put the requested files from your local data source into<br />

the campaign directories. You could also implement a download script, getting, e.g., IGS<br />

products from an ftp server.<br />

# Copy required files<br />

001 PPP_COP PPP_GEN ANY 1<br />

PID 001 PPP COP: This script copies the needed files into the respective campaign directories.<br />

If appropriate, some file names will be changed according to the BPE variable<br />

V B (defining the prefix for a priori files), and/or a session specific date. The BPE will<br />

stop with an error if one of the following files is missing:<br />

File type Source directory Destination directory Renaming<br />

RINEX observation files ORX RAW no<br />

IGS precise orbit file ORB ORB yes<br />

IGS pole file ORB ORB yes<br />

IGS clock file ORB ORB yes<br />

DCB files ORB ORB yes<br />

20.4.1.2 Prepare Pole, Orbit, and Clock Information<br />

This block converts the IGS pole information to <strong>Bernese</strong> format, generates the orbit information<br />

in <strong>Bernese</strong> standard orbit format, and extracts the satellite clock information from<br />

the IGS clock file. You always should use consistent orbit, satellite clock, and pole files to<br />

obtain reasonable results for the PPP.<br />

PID 101 POLUPD: Program POLUPD extracts ERP information from an IERS formatted<br />

pole file (extension IEP) into a <strong>Bernese</strong> formatted pole file (extension ERP).<br />
