I tried the Canadian Precise Point Positioning service, and find their output quite interesting.?ÿ Other than the position results, it gives hardly any of the same analysis information that OPUS does, and several graphs that OPUS doesn't.?ÿ It is a free registration and doesn't ask if you are Canadian.

I think my mode of operation when I have a problematic session will be to run OPUS-S to get its estimates, take that XYZ position result, and edit the RINEX file to make that the starting estimate, and process it on the Canadian site telling it to use kinematic mode.?ÿ Unlike OPUS, this service uses the ARP height and initial estimate in the RINEX file.
The kinematic report shows short-term position results throughout the session with sigma, so you can see what times produced the most consistent results.?ÿ It also shows your receiver's clock stability, estimated tropo delay, and some other stuff.
I have used the NR-CAN service a few times, but it has been awhile. A good alternative to OPUS if it goes down.
