How old is the underlying work? ITRF v. NAD83, HARN??ÿ
I just acquired a 1950 Mils T2. It??s a gem. It had an optical plumb, and the leveling screws and does not have tribrach interface. Compared to muc...
@john-hamilton ive never seen the index change over time or with use. Storing a T2 laying down is not a good idea. The lubricants in the main bearin...
@along ok, reading across the top, your choices are 90-00 or 90-04 ?ÿ acriss the bottom it??s either 89-56 or 90-00 ?ÿtherefore 90-00 i get that i...
@john-nolton note: he has a newer 120? reading micro. Not like the old guns with only 60 units.?ÿ
@along in your pic the index is just offset. Learn to live with it. I think all my guns are like that. I read across the top and across the bottom. A...
I bought a Kern K1-A off eBay. And it came with nearly new really nice wood Kernpod. I figured the tripod was far more valuable than the gun.?ÿ
@field-dog i believe that was adjusting the gain of the receiver. Like setting exposure on a digital camera ?ÿ(more or less the same)?ÿ My trusty HP...
@true-corner If we all measure differently, then why is it that my EDM agrees with the local CBL, and phase differential post-processed gps baseline ...
@tim-v-pls So the measuring wave length is meters. And the measuring wave modulated on a carrier wave is by an oscillator in Hertz. So the EDM??s ba...
@jonathan50 But not your elevations. XY can be plane, Z not.?ÿ
@jonathan50 Nothing preventing someone from working in spherical coordinates. SPC/UTM are optional. I wonder if the Great Trigonometric Survey of In...
@mightymoe and all distances are horizontal distances?ÿ
@john-nolton I like tropical stars. Polaris is too high. A low VA has its benefits. And in winter the sun is good pretty much all day.?ÿ
@john-nolton I??ve filled in all the parts and pieces for my 2021 spread sheet, and tested. Mica has everything, if you look around for it. I calcul...
MICA sidereal time output is interesting. mean sidereal time 09-Jan 0:00:00 UT:07:14:60.9421 Apparent sidereal time is only given in seconds:59.9523...
@samlucy3874 I just look at the pictures.?ÿ
@john-hamilton its always a good way to start the year. The first test sun shot of ??21 hit inverse for 2.3? at 12 miles.?ÿ Q: how to convert geo...
