Trimble TBC - floats on post processed kinematic

I have found with TBC there is not a lot you can do. In the older processors I would raise the elevation mask to 15 and then 18.

What can be done to eliminate the floats without redoing the field work? For instance, eliminating satellites? What else could I do? Thanks for all your reply's.

John is WAY more versed with TBC than me; however, when I run into an issue like you have, AND I've collected at least 10 minutes of data for under 10k and a minute per kilometer thereafter, I use the session editor. Right click on the base line and it will give you the option to open the session editor. From there, you can trim cycle slips. Finally, if that doesn't help, process the baseline and hit the report button. In that report, you will notice several graphs that show sigma values AND the time corresponding to the graph. On the rare occasions where one gives me a ration of crap, I generally notice that the data in some part is VERY NOISY and when I trim that time out of ALL SV's, then it processes quite well and I move on with the work.

Hope it helps.

John, you can change the mask in the processor in TBC under the project settings.

Kris: what I meant was that it didn't seem to help as much. In the early processors, raising the mask made a lot of difference. As the software developed, i think the deleting of poor observations at low elevation angles was more and more automatic. So changing the mask now seems to have little effect.
