I agree with Bob Krohn. That is the first thing I thought of, the scale factor.The way I did it in the old days (before computers and least squares, w...

On long monitoring jobs we hook to an external 12V battery via cable. If you ever do that, you should still leave a battery inside for proper balance.

Here is a good one...This is a station near where I live that I used to use as GPS control in the pre-HARN/pre-CORS days.and here is the image to prov...

Your Backsight Should Be Horizontally Near Polarisyes, it would be great to use the dc. I initially thought it would be impossible until I realized th...

Your Backsight Should Be Horizontally Near PolarisSeveral issues with using the time in the DC. It depends on what data collector hardware and softwar...

The difference in D+R does not matter as long as you observe on both faces and use both in your comps. Since it is a bit harder to observe on an astro...

I would say multiple points. If you have a least squares program with simulation capabilities it should be easy to see which is more beneficial. You w...

There were also problems with ftp. I was writing a program last night that connects to CORS via ftp, and it wasn't working. Of course I didn't know wh...

OK. Thanks. I did not know that.

I think it is a .lev file?Here is an example: b,16,0090A29A,N273,683250,1410210851,N273,,g,15,10180,15000,69343, 0,0,N273,,0852i,15,5520,15000,68791, ...

I don't have an answer for you on that (Chuck Ghilani might). I use MICA to do astro comps, and I got 259°09'15.1" for the topocentric azimuth. The di...

Thanks for the insight. Yes, my agent is asking for a list, but I am inclined to only put on items with high value, say over $3000 or so. I am going t...
