Hi every body.
I have two promark 3 units, one of them needed to change its main board. after that maintenance a strange problem appeared.
Now I cant drag both files from base and rover at the same time to GNSS software. So I drag file from base only and hit to import then choose download data again and drag the file from the rover and hit import and adjust.
another thing. If the file from rover is STATIC i get fixed solution
If the file from rover is KINEMATIC the solution always float.
I need your help please. any body have an idea what is the problem or any suggestion for solution?
dragging files to windows explorer? sounds like a USB driver problem. maybe there is an updated USB driver for the promark. I know that I couldn't connect my Sokkia GSR to windows 10 because the specific USB driver for the novatel board was not installed or updated on the win 10 pc. after searching for it on the novatel site, file transfers to/from the GSR was solved.
?ÿ
the fix/float solutions for static/kinematic also sounds like an l1/l2 type of a problem. are you sure that the board is l2 ready? I think ashtech (or maybe it was topcon) at one time sold l1/l2 ready boards but you needed to activate the l2 bands. I mean maybe the new board does not have l2 capabilities activated? l1 could easily solve for fix in static mode. in kinematic mode, fix results are easier to get in l1/l2 receivers.
jt1950 thank you for attention,
I usually use SD memory cards to save files on the unit, so i remove the memory card from the unit and mount it to my PC. so I dont think it is a USB driver problem.
How I can check for L2 compatibility??ÿ
The Promark3 units were definitely L1 only.?ÿ No L2.
As for the float solution status on files that are Kinematic, to get the best results, you should be doing an initialization occupation with the rover unit of at least 5 minutes, or 360 epochs.?ÿ The units were supplied with a kinematic initialization bar kit that was to be used for the rover initialization occupation.?ÿ I always found that dismounting the rover antenna from the bar made it likely that the base antenna would be disturbed in the process, rendering the initialization session worthless, especially if you are using something other than a tripod/tribrach setup for the base.?ÿ The purpose of the bar was to provide a know 20 CM baseline to process against for the rover receiver file initialization.?ÿ I found that five minutes was sufficient to initialize on a point of unknown location.?ÿ It would be useful to occupy a point that could be reoccupied at the end of your kinematic session.?ÿ I understand that GNSS Solutions processes the baselines and when you perform an adjustment, it adjusts forward and backward, making reoccupying the initialization point desirable.
In the absence of other qualifying information about your workflow in the field collecting the data, inadequate initialization time at the beginning of your kinematic observations seems a likely suspect.
If you wanted to upload a set of files, I would be happy to look at them.
I have had to transfer one file at a time into GNSS Solutions and once I get them all transferred, I can select for it to make a solution or whatever in L1.
It is slow when there are many sites to download, it still works great.
You do not need to drag raw date files into project or GNSS. I don't even have them on same computer when processing. Non RTK kinematic with PM3s never worked good to start with. Static observations work great, even today. My 2 cents: leave both units running for twenty minutes; rover with one unit (while leaving other unit running) at 2 to 5 minute per stop; set control points ever so often in case you loose lock; return to original point for last shot. If you are just locating edge of swamp, tree line or creek, use sub meter.
