Dear Liping Ji,

In my opinion we should not try to give it another name.  SLR is just a technique to study geodesy.  It is the same as in geophysics.  We use different techniques, such as magnetics and gravity etc, but it just stays geophysics.

We can use SLR to evaluate gravity field models of the earth, which translates into the shape of the earth.  SLR can also be used to evaluate earth tide effects, but so can other techniques.

SLR it is just a different approach to study geodesy, and should not be treated specially above other geodesy techniques.

But,  this is only my opinion.

Dear  Stoffel C.J. S. Fourie,

Thanks for your answer.Your opinion is full  of thought ,and  I mean SLR , GNSS and VLBI,as you say ,just a technique  to study geodesy ,then ,should   we name them SLR Geodesy, GNSS Geodesy and VLBI Geodesy? In satellite gravity, SLR technology using in it, it should be a branch of SLR Gravity/? Can  SLR Geodesy be a branch of Geodesy,or of Satellite Geodesy?

Dear Liping Ji,

It is good to think about this.  However, I don't think so.  It falls under a broader term of "Space Geodesy" Techniques.

Kind regards

Stoffel

Dear  Stoffel C.J. S. Fourie,

OK. We may just name it as SLR,and research its using in geodesy,geophysics,etal.

Best wishes
