Interesting. Quite similar to my workflow. The differences being. • Atmospheric corrections are applied and included in the deliverable as part of the quality assurance report. • Utilising Face 1 and Face 2 on orientation. • Utilising “Fine Lock” instead of “Auto Lock”
So basically, running rounds will average out the angles/distance measurements of your backsight and foresight, effectively changing their positions but the CP in which you set your total station up will stay the same? Does that mean rounds work in the opposite fashion when doing a resection? Only the point the total station is set up on changes based on the averaged angles and distance measurements?
When you're measuring rounds when doing a resection, It's assuming the points you're measuring off of are fixed and not adjusted. As it measures each round it's weighing out the error of the resection based on the geometry, how far away your points are, etc. So yep, eventually it will average out the error to a certain degree (you can see your resection residuals), and measuring rounds just helps make sure the averaging it's doing for your station setup is reducing the chances of a bad observation messing up your station's coordinates. It does NOT adjust the coordinates of the points used in that scenario, but the residuals you see will give you an idea of where the error in your control is (Note: does not apply to 2 point resection. That's the danger of 2 pointers...If doing a 2 point resection, discard it right away if you're not getting 0's in your residuals, and always do a check shot tie). Measuring rounds on a known point and doing a traverse is the ideal way to establish high precision control. Doing a resection and then measuring rounds on your resection point is a good way to find out if your control is bad, or if a target is out of calibration. It's more of a blunder check really. You really shouldn't be establishing control with measure rounds when using a resected station, but it does have its purpose. For example, when I'm doing high precision layout of something like anchor bolts, I'll often use measure rounds to tie into a temporary check point. It usually will be as far away as I'm willing to do layout. Then when I do another resection to keep carrying on my work from a different setup point, I'll tie into that established check shot and see how much error I could realistically expect to be floating, since check shots and residuals don't always tell the complete story.
@@ron6625 Hey this is very useful information. We just got all new trimble equipment so anything like this is valuable info for the next guy. Appreciate your insight.
That's a very helpful video, but there is a question coming through my mind. When you proceed with your traverse routin and you transfer your instrument from station to station then you need to, somehow, turn off the instrument so the servo are not harmed during traverse. So how to do this new station set up properly so the traverse routin will be recognized in TBC? Thank you for you answer.
So, there are no servo’s in the Trimble S series instruments. They run on a magnetic drive. When Traversing jut remember point 1 is point 1 not 14 or 1a. When your closing the traverse use the original point number for that point and say store another. Access and TBC will recognize that as a traverse.
@@SurveyingWithRobert Thank you for your answer. It brightened in my head the traverse idea. Also as I understand, moving the TS from tripod to tripod without switching the instrument to "stand by" or turning it off completely won't harm the compesator and the magnetics drives?
Robert, excellent videos! I think the terms Trimble uses in survey rounds are confusing, wish they would reword things. On a side note, I think a lot of folks would benefit from a video on a closed loop traverse, how to name the redundant points and how to adjust it in Access. If you have Trimble's ear, they should also provide a way to undo a traverse adjustment done in Access. If there is a way, I don't know how to do it. Keep up the great videos!
What I’m confused about is if want to say shoot BS direct then BS indirect then my FS indirect the FS direct will it do it like that for traversing. Solo and single range pole life. I’m coming from a Ranger Data collector
great video, I was wondering whether there is a way to skip a point and come back to it in the set to remeasure it. The scenario I'm thinking of is when you're surveying in an urban area with cars going by, say there is a parked car there, you would want to skip it until the car moves and then remeasure that point again all in the same set/ round. Is there a way to do this?
You can do it that with Leica - it works slightly different - you can measure each point as many times in a row as you need, , then do the same to any other point and so on. I tried to achieve that on trimble, but didn't figure it out yet.
Just got the new sx10 testing it out finding what its limitations are. Pros and cons... I turned the Wi-Fi off and tried to only use the radio 200 ft away it was losing radio signal. My channel and Id at the moment is set at 1 and 1 ..I wonder if I should change that to something else to get a better signal or should I just rely on the Wi-Fi I believe it uses both I'm not mistaken... Any advice...
So the same radio that’s in all the S series robots is in the SX10. You should be getting 1200 feet or better with the 2.4 GHz radio. Check your antenna on the collector. I have experienced bad antennas causing that problem.
