Submitting an Occupation to OPUS
NOTE: The iGx Dowload tool will run under Windows XP however it is not possible to
submit observation files to NGS OPUS from a Windows XP machine. This limitation is
imposed by the NGS, not by iGage and there is no work-around.
Once all of the new occupations have downloaded you can submit an occupation to NGS OPUS, NGS
OPUS-RS, RTX, AUSPOS. IBGE or post-process them using other software / services.
Click on an occupation to select it:
Click on the 'Submit to OPUS' button:
The currently selected occupation will be processed and prepared for upload to OPUS:
1.
the file is decimated to 15-second epochs, header information is stuffed
2.
the file is run through TEQC to insure it will be acceptable to OPUS
3.
an Observation file and a Navigation file are generated
4.
the Observation file is compressed into a ZIP file
If the ‘Show Advanced Settings’ is set to “Simple” then the program will skip directly to the ‘Verify
Filename to Upload’ screen (shown below.) If ‘Show Advanced Settings’ is set to “Normal”, “Support
OPUS-Projects” or “Advanced” then this ‘RINEX Solution’ helper screen is shown:
