With respect to references to non-NGS sources of VERTCON, be advised that they probably use version VERTCON 2.1. This version has been superceded wit...

Good to see someone from your part of the world on this site.?ÿƒ??Kuzu zangpo laƒ? Are you teaching at?ÿJigme Namgyel Polytechnic, Royal University...

Depends on where you are...

@cf-67 No problem. I understood what you meant. I am happy that you got some real world examples. I too have problems with the term ƒ??geoid height.ƒ...

@mathteacher My reply to your post was due to my trying to understand what I was missing when looking at your two points. I missed that your were com...

@mathteacher (Update) After replying, ?ÿI re-read the original post. I note that the OP author uses ƒ??H (geoid)ƒ? when he clearly means H (orthomet...

@bene1 Nice find. Unlike some other pairs mentioned, this clearly shows what the OP wanted to find. Looking at your second pair, I was reminded of s...

One of the key points to remember when dealing with the three height systems: orthometric, ellipsoid and geoid (distance from the ellipsoid to the geo...

Pending clarification from the OP, I interpret his reference to ƒ??altitudeƒ? to mean height. Also, his reference to UTM coordinates as a potential s...

FWIW, the NGS Invers3D tool does provide results in both DXDYDX and DEDNDU. I also add a graphic from the Deakin paper referenced in my previous post....

The original poster wants to transform latitude, longitude and heights (LLh) to North, East and Up. What he wants are 3D values in order to generate a...

When you indicate that you took five (5) readings and took the average, do you mean that you setup over the sites and transcribed the autonomous readi...

As I am unfamiliar with the GNSS processing software you are using, I can only provide generic guidance. I note that I had forgotten to address the K...

@bill93 Why here is a printed copy: BTW, the clear scanned copy you linked and I couldnƒ??t access was probably due to having to enter a displayed ...

@bill93 if interested in this topic, have you read Rappƒ??s Geometric Geodesy parts I and Ii

I like Rappƒ??s presentation in/p>

@bill93 FWIW, your better copy link gave me a Error 403. I evidently need to update my eyeglass prescription to read the original.

Not having processed non-GPS data, I do not know why your parameters opt to solve for an L5 and B3 combination. I am assuming B3 is a Beidou frequency...

I like this reference that includes some Matlab code for working with RINEX files. ?ÿ ?ÿ The first link on this page is to a locally-hosted 2015 ...
