Calculation of the Distance to the Moons Apogee/Perigee ?

[Bjarne]

I want to calculate whether the perigee / apogee of the Moon always takes place at the exact same distances (radius to Earth) as measured by the LLR (Lunar Laser Ranging).

I trust that we know the size of the orbit of the moon very exactly, and also that the orbit is growing larger.

But I want to check whether calculation of the perigee / apogee happens the exact same distance as measured, to test if there should be any (periodical) distance (radius) anomaly.

My questions are;

• Is that already done?
• Does it already exsist such software?
• Who is into that “business” ?

No, I am looking for a much more accurate orbit data of the Moons orbit, I think I have to program it my self
All advise are welcome.
