We had a similar incident a few days ago with a Topcon raw data file. 1.5 hours of data was gathered a few days ago for an OPUS submission. The date...
We used to use mirrors. Of course you had to flash it when someone is looking but it works great.
I used 4000 SST's for several years until they were superseded by the SSi's. They were fine workhose receivers that we used primarily for static but ...
Shelby's comments are very interesting to me. (I don' t know how to copy a previous post as a reference). Nice confirmation that several RTK session...
Let me qualify: Static and RTK results are derived from the same mathematical process. In that sense they are the same. They are both double differe...
I have had errors in the script of OPUS solutions one time.
It all depends on how "repeatable" you need the control to be. Static and RTK are fundamentally the same thing. RTK just normally consist of very sh...
RTCM protocols were invented for what you are trying to accomplish, although most systems will also use CMR & CMR+ which originally were Trimble p...
The link below should get you going. It's from Seattle's VRS network which is a Trimble VRS network. Tennessee's network runs on Topcon software but...
Paul in PA said: ÔLeast Squares Adjustment does not make observations better, but it does make them different.I partially disagree. I think any adj...
Totalsurv, This is probably more than you are for but the following is my "journey through least squares adjustment": In my opinion Least Squares ad...
Two centimeters is a significant difference and I would certainly query both Trimble and NGS about this. In the not to far distant past, there were ...
You might want to connect with Kresmir Kusevic a Croatian I knew several years back. He is one of the most brilliant GPS data processors I have ever ...
It seems to me that under canopy positions with fixed solutions that don't stay fixed very long need to be checked now and then with completely indepe...
In my opinion, in any kinematic project RTK or PPK you have to have enough check points to be comfortable the results are what you say they are. In o...
John, Can't agree with you more. I started surveying in West Virginia in 1974, continued surveying there for about ten years. Too many trees for muc...
In theory you're certainly correct, but in practice I doubt it will make much difference. Ultimately your want there to be a minimal amount of change...
Nice to see something that solid, but after years of looking at monuments and measuring to them, old and new, I'm beginning to wonder if any of them a...
VDATUM available free from NGS will convert between different vertical datums. Tying to monuments with 29 values is better, but VDATUM is better than...
