Constructing horizontal displacements

Said please, what is the order of stages (or algorithm) for constructing horizontal displacements in a given geographical direction?

Please have a look at these topics:

Thank you for the links provided.

I have a task in addition to the vertical displacements to build another LOS-horizontal displacements with an area of two orbits (descending and ascending) in the North-East direction. How to implement it?!

(as far as I understand from the approximate forum, this stage is implemented when converting the phase to displacements by formulas conversions)

Ways to approach this are discussed in the linked topics.

We have also created a ticket for this task, but I can’t tell when it will be finished.
