Couldn't get fix with cors

I’m still observing reach with cors base station. But still not get fix. I use gps glonass 5Hz, connection is good.

You need to set Glonass ambiguity resolution to off when using Reach with CORS as base station has different inter channel biases.

Hi, thank you for your response.I Glonass ambiguity resolution to off, then couldn’t get fix. Then turn it on, still get float.
Actually i must flying here by plane to get cors base station, i really want to get fix with cors base station. Maybe this Sunday i will back here again.

How long is the baseline?

Please upload raw logs for rover and reference.

I’m not sure, but i think under 50kms, about 20kms maybe.

I always try and error, so i wait 10 minutes, not fix, i change the configuration, until more than an hour.

Would you share best configuration for connection to base cors?

No option to use VRS? At 20-50km baseline it would be better if you use static mode instead of kinematic if the goal is to measure points.

Yes, i used static mode. And what is the better choice, on or off for glonass integer ambiguity? I plan Sunday to observe again.

Your first screenshot has Kinematic, that is why I recommended Static. With CORS it must be off as you are making RTK between different receiver types.

That’s one of my observation, there is other screenshot

But sorry, i have one question that still has no answer, which one is better, glonass integer ambiguity off or on?
And should i choose fix and hold or continues?
Thank you.

I would be using fix-and-hold.

Wow, it’s really the fastest response that i ever received. Thank you, i will back to the state which has CORS, and use this configuration. I hope i get fix soon.
Correction: @bide is fastest too, ever help me…
Thank you for your concern @igor.vereninov.

Not even trying to compete with @bide :slight_smile:

Please don’t forget to have the raw and reference logs so that we can try to post-process your data.

No, i never compete all my friend, everyone help me, so they are my friends. Reach rtk kit help me to finished my job fastest then every other job, i will always remember that. All body in this forum is my friends, such i get ground plane configuration, you see signal bar in my screenshot. So, i will never compete all my friends.
Sorry for misunderstanding, my friend.

Hi, how to set base coordinate when we do post processing by cors reference file?

Choose Rinex header, is should be there.
