Hi! my name is Michael Elbert,Jerusalem,Israel. I use extansively RTK Leica for controls for road alignment.
However accurate that might be I still adjust the traverse line,though some colleagues think it is a waste of time.
What is the practice you follow?

Grrrrr.... anyone have a Carlson Explorer II loaner? Another one bites the dust. Sending mine in for repairs and sure could use a loaner.

Field testing the Trimble series one R8. Big difference noticed! Looking forward to the 3rd series show...

Off to Jury duty i will check in Later welcome it is refreshing to have the chatter...

This (GNSS)is a place to remain very humble. I see it like a nest of baby birds, mouth open and the feed me sonar turned as loud as it can be.

we just added 2 more satellites giving us 32 in our GPS constellation. Glonass, Galilaeo and Compass gaining population aswell. We have 5 constellations being tuned up as we type away...

L5, L2C are now sending great signal...yet they are still tweaking its ability and integrety.
This is all good news to those willing to seek it out and gain the knowledge as we share data.

I don't see the PDF's of the news article. It may be the way the download works if you have any suggestions let me know.

Frank, agreed the setup is everything. The Old Phrase garbadge in garbadge out apllies as I am sure you agree. The frustrations is often an indicator of the close enough mentality that frustrates me... :)

This technology is as good as the hands that use and since it is growing in strength so fast. The user MUST stay in tune. These forums are and Idea way to embrace the constant change and share the wealth of knowledge gained by our many varied experiences with it.

The DOT sytem is also growing fast. Discussions of plugging into the National CORS Network is gaining strength also.

Look for the article later today, I agree with the need to constantly be informed on new technology. I just get frustrated with the lack of uderlying knowledge of the baisc GPS principles. I just recently had a conversation with a local surveyor who wondered why, when using his RTK system (two units) doing radial topo, could not get consistant elevation check at his base control. We had a really long discussion on proceedures to help eliminate that but I think the increased effort frustrated him.

I did forget to talk to him abot equiping to ramp up use with the NYSDoT system, it would have improved his network and his reliability.

Frank, I would love to see the article. It is entertaining at time when surveyors say things like we used GPS back in the 80s or this isn't rocket sience anyone can use GPS.

That is like saying because you where exposed to the us of the 8track that you have a better understanding of how to you usethe RW DVD HD technology to today and honestly GPS is rocket science.

The technology of the past has a thumb print as I remember the DOS commands that we could use to create code for games as a kid. The ever growing constellations of satelittes that circle the globe and the strength and relability of the signals are very quickly turning heads and making the industry realize this GPS is very able to sustain a reputation of exellence that seems to be changing the surveyorss world fast.

I look forward to staying on the cutting edge but, I will always want to be able to take a tape and create the job with what some call primitive measures...no pun intended...
Our system gets use withing 8ths of an inch horizontally, and can vary on the vertical scale 1' to 1/2".
