Globk Coordinates Documentation
This utility provides xyz (ITRF2000) and lat/lon/ht (WGS84) coordinates from the most recent weekly GLOBK run at SOPAC. SOPAC uses the following procedure to obtain weekly GLOBK coordinates:

1) Precise orbits are created daily using three global GAMIT processing networks, which are then combined in a daily GLOBK run. These are created four days after the day of interest, and use the rapid IGS orbits as their apriori orbits.
2) When these orbits are available, several regional networks are processed, tightly constrained to the orbits obtained from the global analysis.
3) Once all networks for a full week have been successfully run, a weekly GLOBK using tightly constrained ITRF2000 core sites is run, using output from the daily GAMIT and GLOBK runs.
