22.7.9 Geocenter Coordinates<br />

Figure 22.25: Geocenter coordinates (GCC file).<br />

Type: ASCII<br />

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

Extension: GCC<br />

Content: Geocenter coordinates.<br />

Created by: ADDNEQ2 (”Menu>Processing>Normal equation stacking”).<br />

Used by: ADDNEQ2.<br />

Example: Figure 22.25 and ${X}/DOC/EXAMPLE.GCC.<br />

The file contains estimated geocenter coordinates in x, y, z (columns 3-5) together with<br />

formal errors (columns 6-8) in meters for time intervals (MJD, columns 1-2) as estimated<br />

by ADDNEQ2 (see Section 15.4.4). In general it makes only sense to estimate geocenter<br />

coordinates when improving orbits in a global solution and applying a no-net rotation and<br />

no-net translation constraint. The results then give the coordinates of the geocenter as<br />

sensed by the satellite orbits with respect to the origin of the terrestrial reference frame in<br />

which the fiducial stations are defined.<br />

22.7.10 Satellite Clock Coefficients<br />

Type: ASCII<br />

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

Extension: CLK<br />

Content: Satellite clock parameters (extracted from broadcast messages, precise orbit<br />

files, or Clock RINEX files).<br />

Created by: SATCLK (”Menu>Orbits/EOP>Broadcast orbits>Extract satellite clocks”) for extraction<br />

from broadcast file, CCRNXC (”Menu>RINEX>RINEX utilities>Combine/manipulate clock<br />

data”) for extraction from Clock RINEX, PRETAB (”Menu>Orbits/EOP>Create<br />

tabular orbits”) for extraction from precise ephemerides, <strong>GPS</strong>EST (”Menu>Processing<br />

>Parameter estimation”), and CLKEST from estimation, CODSPP (”Menu>Processing<br />

>Code-based clock synchronization”) for correcting GLONASS satellite clock offsets<br />

to <strong>GPS</strong> time.<br />

Used by: CODSPP (”Menu>Processing>Code-based clock synchronization”), MAUPRP (”Menu<br />

>Processing>Phase preprocessing”), <strong>GPS</strong>EST (”Menu>Processing>Parameter estimation”), and<br />

CLKEST.<br />

Example: Figure 22.26 and ${X}/DOC/EXAMPLE1.CLK.<br />
