The X9 Download tool allows you to submit jobs to
alternative services like AUSPOS and RTX. Typically these
alternative services closely match 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:

Here are some general rules to help judge the quality of a
solution:
The orbit
[precise]
should be precise or rapid (not-ultra rapid.)
> 90% observations used or > 80% # Fixed Ambiguities
> 50% Fixed Ambiguities or > 95% observations used
Overall RMS < 0.030(m)
