I'm hopeful that SPCS 2022 in many States, including Texas, will be LDP. If so, Loyal, you will have been a big part of the impetus for it.

I'm a big fan of lump sum. I opened my own company three and a half years ago and, with few exceptions, every job I've done has been lump sum.?ÿ ?ÿ I'...

That is a very good video. I stumbled across it myself a couple of days ago. It reminded me of this article from 2001: ?ÿ ?ÿ The geodesy that was dis...

By the way, residuals only tell a fraction of the story. They will tell you nothing about a scalar error in the original control. You absolutely MUST ...

I seldom (bordering on NEVER) allow a localization to apply an over-determined scale factor. I will apply a geodetic combined factor if localizing usi...

Number one killer for me was always forgetting about overwritten points. The coordinates of the first point might be gone but the raw data still exist...

I would encourage you to consider adding a Javad base to the Triumph-LS. With a Javad base, you have access to DPOS for post-processing your base raw ...

@linebender How can I argue with such a stalwart authority as the screen capture from a major CADD manufacturer? I humbly retract my comments.  

This is the comment I submitted to NGS: There are several issues which perplex me regarding the deprecation of the US Survey Foot.1. As noted in the p...

1. If your Epoch 50 transmits on UHF and the Triumph-LS has a UHF radio, then you should be able to receive corrections from the Epoch 50, but we don'...

As has already been stated, tilt correction is based on the amount of tilt from plumb, the direction of tilt related to the coordinate system, and the...

I will be at Intergeo this year doing product demonstrations at the Javad GNSS booth. Would love to meet any fellow RPLS'ers as well.

Title issues in Texas that might be caused by new descriptions are avoided by using careful wording, particularly in the preamble. For example, the pr...

I'm not certain. If the 50ppm zones or LDP (20ppm) zones are created, Grid north will be entirely different, I'm sure. If the default system is used, ...

The paper describes how the IFVM will work. It will be like HTDP, but ultimately much better. Movements may be described by complex functions rather t...

It appears NGS has decided to perform the plate transformation about the Euhler pole and apply motion functions (local velocities) as well. It also ap...

Yes. That part seems somewhat prohibitive, but not terribly so.

You will never see the difference in international feet and US Survey feet in a total station. It's only 2ppm different (0.002 per 1000).

If, hypothetically, NGS only provided coordinates in meters, there is no reason that day to day work would also need to be reported in meters. It just...
