Jps2rin only works one way, but Javad has opened up a special server to accept RINEX files directly: DPOS automatically applies HTDP transformations ...

Jim, you might try using the Giodis engine instead of the Justin engine. The Giodis engine is designed for long baselines (up to 2000km) while Justin ...

Jim, were you using US CORS or IGS for the network?

Regarding DPOS, I was corrected by the developer. He said that only GPS and Glonass are used in the RINEX version of DPOS. This is still an advantage ...

Mark's article is a wonderful resource. One of the limitations of some of the processing services is that they output in the current epoch of the late...

Hi Lee, I believe DPOS uses all constellations (at least all constellations simultaneously recorded at the CORS and the user station). I know that it ...

I'm not sure why the OPUS solution would be considered to be always correct. Does the NGS make this claim about OPUS? I'm looking forward to trying ou...

That transformation utility in Carlson is fantastic. It's a Helmert transformation (same as is used in a localization). It's an excellent tool for com...

Even before I was putting everything on a geodetic bearing relation I still would not use the record bearings to do a bearing-bearing intersection bet...

Update on development of Javad J-Mate: In our conference call today, Javad revealed that a tilt compensator with a 15?ø operating range and an accurac...

I would recommend the Triumph-1M over Triumph-2 for a base. Like Adam I use the Triumph-2 as a base and it works very well. I like the internal radio ...

What hall and booth are you in Mark? I'll be hanging around the Javad booth for a while.?ÿ

@Field Dog did I understand correctly that you observed both pair points twice? If so, what was the actual difference between the first observation an...

This is my favorite use of tilt compensation as well. Shots taken about as fast as you can walk with no need to touch the keyboard.?ÿ

@gschrock Interesting that the receiver doesn't need be fixed. Perhaps they are using displacement from the GNSS (which doesn't require a fixed positi...

I can't speak for Trimble or other manufacturers with tilt compensation, but I think regardless of the sensors or calibration used, the only way to ge...

Oh, and I do take lot surveys from time to time, but I'm not cheap, I'm just fast. Having said that, it's nice to fill in a week to keep a little cash...

I like solo surveying. I've been at it for a little more than two years and enjoy the benefits. As others have mentioned it comes with its own trouble...

I'm a little disappointed by the lack of clarity regarding dynamic coordinates. Some resources indicate that it will be basically like ITRF, some that...
