Glad to see you got promoted. And if you look at the network uncertainty of the NGS points I think your azimuths may be superior. Cool following along...
So, the standard residuals are all below 3 sigma?So all the positions are valid for a weighted averaging?
I've been working on developing an SOP for myself and this is the way I see a complete pre-adjustment of observables "reduced".Note the long path to a...
An ellipse has a major and minor radius at right angles. Any azimuth other than 0, 90, or 270 and you have to account for that. Azimuth allows you to ...
Because the ellipsoid is not a sphere (for our purposes) the radius varies with azimuth and latitude. In fact it differs even on the reverse azimuth b...
The 6 was the standard tribrach for T2s and targets from 1960ish to about 1970ish. It's old but gold.
Obviously too much time on my hands today....What would be the reason a manufacturer could not produce (at least to the limits of human sensibility) a...
Conrad,I follow your thinking in reply to my post but not the manufacturers thought process involved in instrument specifications. If any manufacturer...
Rather than deliberately degrade excellent observations, isn't it more likely that a less effective and hence cheaper sensor is used to read the circ...
P.S. What gauge is that in the avatar?
Bingo! Not demented yet!
Was it Professor Cliff Mugnier (sorry on spelling) who wrote all the articles on National Grids? I may be misremembering. Anywho, welcome aboard matey...
Excellent discussion with illustrations and examples by Jerry.
By "control" I meant the two NGS disks. And really nice work.
At 1.7" it sounds as if you've exceeded the specs of the instrument and the quality of the ephemeride data. The control probably isn't that precise ba...
Cary,I'd go back through this forum and check all the cad related threads. There are some great tips hidden in there.You need to know how to import as...
I hate pounding wood into rock. And where's the tack?
Sounds like I'd hire you. Good work.
On land or over water?
