The LAMBDA method is described in the following links: Do a Google search for LAMBDA method for integer bias estimation for more. As other replies n...

The integer ambiguity refers to the un-measurable number of wavelengths transmitted by the satellite before the receiver starts logging. There is one ...

I too hope that someone ƒ??well qualifiedƒ? will respond to the tread. Unfortunately, the subject is not likely to be addressed in short, easy answer...

More specifically on airborne gravity, here is a good paper:?/p>

If I understand correctly, you are concerned with how the impacts of masses are accounted when determining the ellipsoid-geoid separation. This is the...

Time to break out the T3! For those interested, hereƒ??s a link to the Manual of Geodetic Astronomy:?ÿftp://ftp.library.noaa.gov/docs.lib/htdocs/rescu...

FWIW, The dynamic height is the geopotential number scaled by the constant normal gravity at 45 degrees latitude. You will note that using LVL_DH in a...

Thanks to Mr. Nolton for finding the digital version of the manual.?ÿ Finding it from the link he posted was a bit of bother. I ultimately obtained my...

Even balanced sights will not save you from: the NCGS has a good presentation at:?/p>

Good suggestion to check published values near project. As for the computation, why not just use LVL_DH? You can use either PIDƒ??s or height and grav...

BTW. the venerable Manual of Geodetic Leveling is available on line at:?/p> Lots of good information about many aspects of this type work.?ÿ The geode...

I always remember what Heiskanen and Moritz wrote in Physical Geodesy?ÿ Also of possible interest is the Geodetic Tool Kit item: LVL_DH. I share the ...

If you are looking at the Z-velocity reported for a CORS network point, you are not looking at a change in height. That would be the DU value. See the...
