If you are processing OPUS-RS jobs in an area with very few
CORS stations, and one CORS station was offline, waiting will
not help. OPUS-Static is the solution for locations where
OPUS-RS is not dependable.
CORS stations can report observations hourly or daily. In
some areas (typically UNAVCO PBO sites) most of the sites
report once at the end of each day (GMT.) So data that is
needed to process your job is not available until 4:00 am
GMT on the day after you collect data.
The iGx download tool allows you to submit jobs to
alternative services like AUSPOS and RTX. Typically solutions
from these alternative services closely match those from
OPUS.
If you submit an observation to OPUS and nothing comes
back, check your SPAM folder. OPUS solutions are regularly
misidentified as spam.
OPUS is sometimes unavailable or takes longer than other
times.
Interpreting OPUS Results
When you receive an OPUS solution by email from the NGS,
it will look something like this:
