10.6.7 Propagating Coordinates to Specific Epochs<br />

10.6 Coordinate and Velocity Related Auxiliary Programs<br />

Program COOVEL (”Menu>Service>Coordinate tools>Extrapolate coordinates”) can be used to propagate<br />

station coordinates from one epoch (reference epoch in the coordinate file) to another epoch<br />

by applying site velocities from an input velocity file. The velocities may stem from an<br />

official reference frame (e.g., ITRF2005), from an ADDNEQ2 multi-session solution, or from<br />

a velocity field model (program NUVELO).<br />

Usually the program is used to propagate reference station coordinates from the reference<br />

epoch to the observation epoch of the current session. If a station is not listed in the velocity<br />

file a warning message is issued and no velocities are applied.<br />
