iG5 User Manual
In general, the resolution is nearly always the same:
“
Wait until more data becomes available and resubmit your
job.
”
If you are processing OPUS-RS jobs in an area with very few
CORS stations, and one CORS station was offline, waiting may
not help as more data may never become available. OPUS-
Static is the solution for locations where OPUS-RS is not
dependable.
