Station Keeping at Sun-Earth libration point L2

Postby Vincent » Wed May 11, 2016 10:13 am

Hi, All

I am trying to simulate the station Keeping at Sun-Earth libration point L2 with the example provided with the GMAT R2015 distribution.
I understand that the strategy is to annihilate the x-component of the velocity when the satellite is crossing the plane xz plane (Y=0).

However the following comment in the GMAT script file leaves some doubts on the strategy to use for the station-keeping...

% Comment: This is for simple example purposes and results in a Delta v
% that is much too high! Delta V's should be on the order of cm/s. The
% targeting scheme is beyond the scope of this simple demo. -SPH

What is the adequate targeting scheme to find cm/s values (as experienced by spacecraft in real life) instead of dozens of m/s?

Thank you in advance for your feedback
