Reduce the directions so that the direction to Target 1 is d00m00s for each set and Calculate the average for each target. We’ve established a quality community of surveying friends, mentors and enthusiasts, where we can all hang out, chat and have some fun sharing our experiences and helping each other. I guess what I was getting at was that you can “test” to see how close you can get to a specified DIN with the above rin process, however given the real world conditions of operating an instrument will rely on how good your transit man is at setting up and dn the gun.

Anyway, one website says that the DIN spec has been “withdrawn”, whatever that means.

That which discloses to the wise and disguises from the foolish their lack of understanding. DIN is a procedure for determining the accuracy, or standard error, of the mean pair of Direct and Reverse directions to a single target.

Usually set up within 0. Space Weather influence on satellite based navigation and precise positioning R. We then want to square the adjusted residual and sum each column.

Finally if I observed a single angle observation for example between two points and measured an angle of 67 Degrees 12 Minutes 20 Seconds then how does my instrument standard deviation of 2″ relate to my observed angle of 67 Degrees 12 Minutes 20 Seconds then – can anyone explain? A Worldwide Repair Service – Visit us at: Or, in the case of Leica, using a circle with known periodic errors in its graduations that is either partially or entirely removed by the reading system software, depending upon the instrument accuracy spec.

Registration Forgot your password? Am I diin in thinking that Trimble have determined, through the Dln standard, experimentation, repeated observations etc, that the standard deviation of angle measurements is 2″ for this instrument- is this correct?

MODERATORS

Conrad posted his results of an investigation of the Leica circle reading system and discovered that the circle reading system in effect adds a pseudo-random error to the direction reading so that a nearly perfectly graduated circle appears to give directions with random-appearing errors with an s. August 3, 7: Factor in real world errors such as sighting and targeting errors, we can show that our measurements, unless being operated in a laboratory setting, will never achieve the numbers stated by the manufacturer.

The error in an angle is given by the equation:. Did you by chance cover the steps idn zenith angle, levels, or EDM in cin lecture? By continuing to browse the site you are agreeing to our use of cookies.

It may have been replaced by ISO Yes, I find it difficult to believe that the other instrument manufacturers aren’t following some version of the Leica method of using the exact same circle in a line of instruments with a range of specified accuracies and then degrading the performance of the lower spec instruments by software. Add value or dkn along.

Do not stamp on the tripod feet. I mean, if you get it, pass it on.

DIN and in English? : Surveying

Sad fact, too many surveyors use poorly defined targets. DIN loosely translated Fin Institute for standards. I mean that the DIN number you come up with for that instrument is specific to that one instrument.

This is equivalent to a marksman realigning the sights after the shots.

I was wondering what does it mean when it says that a Trimble S6 is a 3″ instrument? Any insight would be very helpful. In other words the difference in price buys the exact same instrument, but with a few more lines of code active in the internal software. Amount and quality of data acquired GPS signal strength and continuity Ionosphere and troposphere conditions Station site stability, obstructions, and multipath. I have the 12th edition at hand.

DIN and in English? Do you have anything on this? Standard errors include error generated by the instrument itself, the observer, atmospheric conditions, etc. As well as not keeping your prism rods and tribrach in top adjusted shape.
