Planetary Ephemerides Generation From Interplanetary Laser Ranging Data

, 2018
With the introduction of Interplanetary Laser Ranging (ILR), the acquired tracking measurements accuracy of planets can be improved drastically (up to a few millimeters) which can result in an improvement in planetary ephemerides of not only the planet ...
