20. Processing Examples<br />

PID 101 <strong>GPS</strong>ESTAP: This script prepares the parallel <strong>GPS</strong>EST run. All baselines associated<br />

with the current session are processed individually.<br />

PID 102 <strong>GPS</strong>EST P: Program <strong>GPS</strong>EST creates a residual file for each baseline. The coordinates<br />

of the baseline’s first station are fixed on their a priori values. Troposphere<br />

parameters for both stations and coordinates for the second station are estimated. The<br />

residuals are not normalized as no screening is intended. <strong>GPS</strong>EST runs in baseline-wise<br />

mode.<br />

PID 103 <strong>GPS</strong>XTR: Extracts a short overview of the previous step. This file is included in<br />

the processing summary (BASyyssss.PRC).<br />

PID 111 RESRMS: Creates a summary of the residuals. No screening is done. This file is<br />

included in the processing summary.<br />

PID 112 RESCHK: Another summary is created, containing various satellite-specific information<br />

such as the relative percentage of observations, the total number of observations,<br />

and total RMS per satellite. This overview is included in the processing summary.<br />

Misbehaving satellites are indicated by a large amount of deleted data and a<br />

high rms value.<br />

Processing (page 391).<br />

20.4.3.3 Create Processing Summary File<br />

In the last part of the PCF an analysis protocol is created.<br />

901 BAS_SUM BAS_GEN ANY 1 103 112<br />

PID 901 BAS SUM: This script creates a processing summary giving a comprehensive<br />

overview of the most important results. It contains the summaries extracted in the<br />

previous steps (PIDs 103, 111, 112).<br />

Error Handling (page 417).<br />

20.4.4 Zero-Difference Processing Example (CLKDET.PCF)<br />

The CLKDET.PCF presents a processing scheme for the determination of station and satellite<br />

clock corrections. These corrections are computed based on <strong>GPS</strong> data for a regional network<br />
