LS static session

[Charles Owens]

How does one go about?
1. Starting & recording a static session.
2. Sending to DPOS or OPUS.
3. What is the suggested length of a session? (15 min for OPUS rapid static)

Thanks

Use a profile that logs raw data and store a point as you would with RTK.
You can go to Files and "Collected with Points" to export the raw data file to a USB and from there copy to PC to upload to DPOS or OPUS
The suggested length of time will vary from place to place depending on the proximity of the CORS stations. In some places you can get by with less than 15 minutes because the CORS are densely spaced. In other places it will require more than 15 minutes because the CORS are more sparsely spaced. You'll need to experiment to see (if you are wanting to cut it down to the bare minimum). For the most precise results I prefer 5+ hours. Of course this also depends on environment. You can't use the bare minimum occupation in bad environments and expect good results.

Thanks for the advice.

Moving to a job without cellphone coverage, and therefore no RTN data stream. I take from your suggestion that we would be able to occupy a point (minus RTN & therefore no fix) and start a collection/session (with the correct profile for recording GNSS data) for adequate time to qualify for an acceptable DPOS or OPUS solution.

Sound like that will work?

yes. but test yourself. no sense in going miles away into the woods only to fail. test your procedures at your home or office and make sure the results are there.

I'm getting too old to walk miles thru the woods and over hills to not occupy a point for static less than 1 hour. Even out in the open sky areas, if you're going to log for 5 min, why not 15 min ? If 15 min, why not 30 min. I despise going back to a point without enough data logged for it not to converge. Enjoy the woods and the creatures around you created by GOD in the knowledge you've got the best equipment in the world for surveying.
